Today we’re going to talk about on-board diagnostics and the questions we hear from folks around Corpus Christi TX who need answers about diagnostic services. They want to know what diagnostics are, what’s involved and what the benefits are. They really want to understand the value of diagnostic scans by a trained technician in Corpus Christi TX.

These are valid concerns. If you don’t understand something it’s really hard to know its value. Let’s start with some history.

Since 1996, all cars and light trucks in Corpus Christi TX have been required to use a standardized diagnostic system to help repair technicians determine what’s wrong with your vehicle. The diagnostic system works with the vehicle’s Engine Control Module – the computer that controls many engine functions.

The computer monitors dozens of components and processes. Depending on what the sensors read, the computer will make adjustments to compensate for conditions and minor problems. When there is a condition that it can’t adjust for, the computer will turn on the check engine light.

It is also called the ’service engine soon’ light on some vehicles. The warning light signals you to get into your Corpus Christi TX service center so that the trouble code can be read and the problem can be fixed. Your service center will have a scan tool and powerful software that will help the technician diagnose the problem.

If you’ve searched for check engine light on the internet, you may have seen that you can buy an inexpensive scanner or go to an auto parts store to have the trouble code read to tell you exactly what’s wrong.

That’s a common myth. The code itself doesn’t tell you what’s broken. It starts you looking in the right place. It tells you what engine parameter is out of range – but it won’t tell you what’s wrong or how to fix it.

Let’s say you think your daughter has a fever. You take her temperature and it reads one 102 degrees. You’ve confirmed a fever, but you don’t know what’s causing it. Is it a 24 hour flu, an infection, appendicitis or leukemia? A fever is a symptom of all of these medical problems, but it takes a skilled physician’s examination and additional diagnostic tests to find out what is actually causing the fever.

An example of a trouble code could be: P0133, which reads ‘Bank 1 sensor 1 circuit slow response’. This means that the front oxygen sensor has a slow response time to changes in the air-fuel mix. If that’s all you knew about cars, you would think your oxygen sensor was broken and would replace it. Now, it could be the oxygen sensor – but it could also be a bad or contaminated airflow sensor, exhaust leak, electrical problem, an intake manifold leak or any of a number of other things.

You can imagine a lot of oxygen sensors have been replaced because of that code. So the on-board diagnostics point the way to where the trouble lies, but it takes some skill and high-tech equipment to actually pinpoint the problem. The cheap scan tools that a consumer can buy do not have the ability to retrieve some of the operating history that’s stored in the engine control computer. That history’s very helpful in diagnosing the problem. Service centers like Dub’s Garage invest a lot of money in high-end diagnostic tools to help solve the mystery and get you back on the road as soon as possible without replacing a lot of parts that don’t need replacing.

So, on-board diagnostics provide a powerful starting place for a highly-trained, well-equipped technician to get to the bottom of your problem. When your check engine light comes on, get it checked at Dub’s Garage. If the light burns steady – don’t panic. Get in to Dub’s Garage soon to have the engine scanned. A flashing check engine light means that there is a severe engine problem. Get in as soon as you can – waiting too long can lead to very expensive damage.

And try to not drive at high speed or tow or haul heavy loads with a flashing check engine light.

Diesel Maintenance For TX

January 28th, 2010 by hardcastle50

At Dub’s Garage we hear from a lot of people who are excited about the new diesel engines that will soon be available in passenger cars and SUV’s. But our TX friends are often curious about the preventive maintenance requirements. People may not know that diesel engines have long been used extensively in Europe and Asia. In fact, in some markets, there’re nearly as many diesel powered passenger cars as there are gasoline.

Here’s who’s announced or is expected to announce new diesels for North America: BMW, Mercedes, Audi, Volkswagen, Nissan, Honda, Toyota, Hyundai and Subaru. Of course, the US auto makers will be expanding their diesel offerings as well. Diesels will become a very big deal here in TX.

You may ask, why has it taken so long getting to TX and North America? There are a bunch of reasons like fuel tax policies and such, but the biggest hurtle was that TX diesel fuel had a high sulfur content – too high for the latest generation of highly refined diesel engines. Recent government mandates to remove sulfur now opens up TX to the engines the rest of the world’s been enjoying for a long time.

Why are diesels so popular worldwide? Well, for starters, diesels get up to 30% better fuel economy than gas engines. And they last a lot longer. And modern diesel engines are refined, quiet and powerful – and there’s none of that black smoke we used to see.

Some people may think that diesels create more pollution. But, you need to rethink diesels. Environmental pollution standards for diesel cars and light trucks are scheduled to be as strict as they are for gasoline vehicles. A modern diesel engine is as clean as a gas engine.

You may also have heard a lot in the news about bio-diesel. The exciting thing about diesels is that they’re not limited to fossil fuels. They can run on fuel made from vegetable oil. There are refineries that make diesel fuel from cellulosic waste like woodchips from lumber mills. There’s even this cool new process where a special strain of algae is used to convert carbon dioxide, water and sunshine into bio-diesel. That’s still a ways off, but you can see that diesel can become a sustainable source of fuel.

And, there are not a lot of trade off’s with diesel in terms of performance. A modern passenger car diesel is very smooth, quiet and quick. Most folks wouldn’t notice any difference. For those who tow trailers and haul heavy loads, diesels will be an improvement.

Now diesel engines are heavy duty, so they cost more than gas engines. But they get better fuel economy – so the break-even point is largely dependent on the difference between TX gas and diesel prices at the pump and how many miles you drive. And diesels have a higher resale value.

Now, let’s get back to diesel maintenance. You have to keep in mind that most of the new diesels are just coming in, or will be over the next couple of years, so we don’t have the maintenance schedules to make direct comparisons yet.

But going off what we already have in TX, we can expect fluid drain intervals to be similar to gasoline engines. Diesels do require very clean fuel, air and oil, so their filters are much higher capacity than gasoline filters and cost more. The engine air filter needs to be changed more frequently as well.

Repair costs are similar. As with gasoline engines, proper maintenance is the key to long engine life and to avoiding repairs. So pretty much what we have come to expect with gas vehicles; coolant system service, transmission service, power brakes, power steering, differential, filters, fuel system, and so on. And the payoff for you, if you’re the kind that likes to keep your vehicles for a long time, is that a properly maintained diesel engine can last for hundreds of thousands of miles.

Getting Your Car Serviced in the Real World of Corpus Christi

January 20th, 2010 by hardcastle50

We get a lot of questions about servicing your car at AutoNetTV. One that we get asked the most is: Do you have to take your car to the nearest Corpus Christi dealer for service and repair? We’ve all asked ourselves that at one time or another. Of course, any new car dealer in Corpus Christi would like to have your service business, but there are a lot of reasons to turn to the automotive aftermarket for routine maintenance services as well as repairs.

First, let’s get some terms straight. New car dealers and manufacturers are referred to as Original Equipment – or OE providers. Everybody else is in the automotive Aftermarket. That includes auto parts stores, quick lubes, tire and service, and repair centers.

It’s important to know how the automotive industry works. Most car manufacturers don’t actually make their own parts and none of them make all of the parts they use. Instead, there are over 5,000 manufacturers that make the parts used to build new cars as well as to repair used cars.

We get a little steamed when a new car dealer pushes the myth that you need to go to them to get “genuine parts”. The fact is that your independent service center (Dub’s Garage) can install the exact same original equipment parts from the same parts manufacturer that supplies the dealer.

One of the advantages of the aftermarket is that they’re free to innovate and improve. The aftermarket is quick to step in and fix design problems in Original Equipment parts. They’re also able to improve on reliability and performance.

When you use your independent aftermarket service center you’ll get parts that meet or exceed manufacturers’ specifications. You‘ll also have the freedom to choose replacement parts that meet your budget, improve performance or are the same as what the factory uses.

This freedom of choice is protected by law. You’re not required to use the dealership for service or to use the manufacturer’s brand of parts or fluids in order to maintain your vehicle warranty. Your local service center knows what products are recommended for your vehicle and can help keep you safely and economically on the road.

It’s like when you go to the hairdresser. They have a wide range of products you can choose from. You can buy something that’s less expensive when your budget’s tight, or kick it up a notch if you want. That’s the freedom of choice you get in the Corpus Christi, TX automotive aftermarket.

Some new car dealerships lead you to believe that only their technicians are able to properly service or repair your make of vehicle. That may be true if you drive a Ferrari, but for the rest of us, the training our local Corpus Christi, TX technicians receive is transferable to our cars.

Your Corpus Christi, TX service center invests heavily in training its technicians and in making sure that they have all of the high tech diagnostic and service equipment to take good care of you. Hey, we live in the information age – aftermarket service centers have access to the latest specifications, problem reports and repair solutions for your vehicle.

Like your hairdresser – she probably knows you. She knows your personality, all about your family, and maybe even a few secrets. Your Corpus Christi, TX automotive technician should also know you, and your car. You can’t underestimate the value of that relationship.

Your vehicles are a big investment and you rely on them so much. You have to have someone you can trust to take care of you. Dub’s Garage can get the right parts, has the training to fix your vehicle and has a very strong commitment to your satisfaction. And for most of us, they’re more conveniently located and can usually perform maintenance services with less wait and hassle.

Now if your car needs a repair that’s covered under its new vehicle warranty, you’ll want to visit the dealership. But for everything else, consider your local aftermarket service center. Options, freedom, convenience – and with labor rates that are nearly 20% lower than the dealership – why go anywhere else?

Keeping Your Car Young in Corpus Christi

January 14th, 2010 by hardcastle50

We live in such a disposable society here in Corpus Christi. It’s amazing all the stuff we throw away.

New stuff comes out so fast, we just toss the old and move on. It seems like when we were kids, our parents were real sticklers about taking care of our stuff. You know, hang up your clothes, polish your shoes, put away your toys. If something got lost or ruined by neglect, tough – we had to do without.

We couldn’t afford new cars very often, so we tried to make them last as long as we could. It’s a good thing that cars are more reliable these days.

They just don’t break down as often. And the good news for us penny pinchers is that a modern car can easily go 200,000 miles with proper care. The engineering’s there and so is the manufacturing quality. The missing ingredient is us making sure we follow the manufacturer’s recommended maintenance schedules.

Is it really that bad to get off schedule? Well, it all adds up. Every time you go a couple thousand extra miles between oil changes, you’ve created an opportunity for sludge to form and clog passages. Then some parts don’t get oiled and they start to wear out faster.

Skip a cooling system service, and the corrosion inhibitors become depleted, and the radiator starts being damaged – one step closer to a failure. The same thing is true for transmission service, power brakes, fuel system cleaning – really everything on your schedule.

It’s also even more important for older vehicles. Those engines and other systems have had more time to get dirty, so they’re a bit more stressed anyway. But it’s never too late to get back on track with your maintenance and to hold off further damage.

It’s just another example of our parents being right. (Surprising how often that happens.) And it really does start with the oil change, just like Dad said. When you get a full service oil change they top off all your fluids and check for other items that are on your maintenance schedule. That’s like your safety net – go in for oil changes on time, and let your service advisor at Dub’s Garage help you keep track of the rest.

Of course, some things are going to wear out along the way, stuff like alternators, water pumps and such. But that stuff is cheaper than a new car payment. And taking care of problems early means they have less time to cause other problems. It’s like having high cholesterol – you don’t want to wait for a heart attack before you address it.

Nitrogen Fill For Tires in Corpus Christi TX

January 6th, 2010 by hardcastle50

So, everyone in the Corpus Christi TX area knows how great helium is – you know, party balloons, squeaky voices. But a lot of people around Corpus Christi still haven’t heard about the benefits of nitrogen in your tires, and how it can help your tires. Here’s some great advice from AutoNetTV, brought to you by Dub’s Garage.

Nitrogen has actually been around for a long time in the Corpus Christi TX commercial sector, but it’s just starting to catch on for private vehicles in the 78414 zip code area.

Why nitrogen in your tires? Air is air, right? Actually, it turns out there is a difference.

The heart of the matter is maintaining proper tire inflation. When your tires are properly inflated, they last longer, handle better and more safely, and save you money at the gas pump.

The problem is that tires filled in Corpus Christi with regular air can lose a pound and a half of air pressure every month. This just happens as the oxygen in the tire seeps out. So if you don’t check your pressure for a month or two, well, you can be significantly low – low enough to actually affect your handling, shorten tire life and waste money at the fuel pump.

How does nitrogen help? Regular air contains about 78% nitrogen. Nitrogen is the largest molecule in air. It’s dry and non-flammable. Air also contains 21% oxygen, which is smaller and seeps out of the tire three to four times faster than nitrogen.

So, a tire filled with nitrogen at Dub’s Garage will take about six months to lose as much pressure as regular air does in just one month. So it’s more forgiving for those who don’t check their pressure every week.

Also, when oxygen is at higher temperatures – like those inside your tire when you’ve been driving for awhile – it oxidizes the inside of your tire. Getting the oxygen out of your tire means that it’ll last longer.

Who’s using nitrogen? Well, let’s start with NASCAR and Indy. These racers like nitrogen’s ability to maintain consistent tire pressure and reduce tire temperatures under very demanding conditions. The US government requires all commercial aircraft to have nitrogen in their tires. NASA and the US Military use nitrogen. The mining industry has been filling those “humongous” tires with nitrogen for years. And semi trucks and trailers are starting to use nitrogen extensively.

You may have heard some detractors of nitrogen. But the studies and white papers from tire and vehicle manufacturers demonstrate that the technology really works.

In fact, a prominent consumer research group did a study where they filled some tires with air and some with nitrogen and stacked them outside for a year. They observed that the nitrogen filled tires did hold their pressure better, but they couldn’t see the economic benefit. But that particular test has very little to do with the real world. Most tires are actually holding up cars and they also get driven around and do a lot of work. So if nitrogen helps them last longer, saves gas and gives safer handling, it’s worth considering.

Corpus Christi Drivers Severe Service Maintenance Schedules

December 31st, 2009 by hardcastle50

Your vehicle manufacturer publishes two auto maintenance schedules. The regular schedule and the severe service schedule. It’d be wrong for us to tell you that everyone in Portland always needs to follow the severe service schedule – but its wishful thinking to say that the regular schedule is always good enough for your sports car.

Contact Dub’s Garage to learn more about Severe Service Requirements for your sports car
You can find us at:
5973 La Costa
Corpus Christi, TX 78414
Or call us at 361-852-7379

At Dub’s Garage we’ll give you the definitions and explain the issues, and you can be the judge. Most manufactures list the following as severe conditions:

  • Most of your trips are less than four miles.
  • Most of your trips are less than 10 miles and outside temperatures are below freezing.
  • The engine is at low speed most of the time – not on the highway.
  • You operate your vehicle in dusty areas.
  • You regularly tow a trailer or carry heavy loads.
  • Driving in very hot or very cold weather.

So think about your typical week. Do you live a block from a TX freeway on-ramp and enjoy a non-stop commute to work in Ingleside or Chapman Ranch? Or are you like the rest of us where 90% of our trips are on the severe service list?

The answer may be different at different times of the year and for the different drivers in your family. Think of the two service schedules as bookends. Let’s suppose your owner’s manual says the severe service oil change recommendation is 3,000 miles and the standard recommendation is 5,000 miles. You know that you need to change the oil somewhere between 3,000 and 5,000 miles. Look at your driving patterns and Corpus Christi road conditions and honestly evaluate which end of the spectrum you’re closer to.

If you have a job in a neighboring town such as Corpus Christi or Ingleside and most of your commute is freeway miles, you may choose the regular service schedule for your car. On the other hand, if you live within a few miles of work and only get on the highway a handful of times every month, something closer to the severe service schedule is more appropriate.

Now why is this so important? Moisture builds up in the engine oil from normal condensation. Short trips around Portland or driving when it’s really cold means that the engine doesn’t heat up enough for the moisture to evaporate. The water in the oil leads to oil sludge that gums up your engine and doesn’t let the oil protect it as well. That’s why you need to change your oil more frequently – to get the sludge out before it causes problems.

Towing, heavy loads and very hot TX summer weather means that your engine and transmission will operate at higher temperatures and with more stress. The fluids will break down more quickly. Additives that clean and prevent corrosion will be depleted sooner. Dusty conditions, which may extend also to areas with high air pollution, mean that fluids will get dirty faster and that filters will plug up and won’t work right.

All of these things can lead to premature wear and repairs down the road. They’ll also hurt your fuel economy. If you want some personalized advice, talk with your understanding Dub’s Garage service advisor. We can help you restore your vehicle to good working order and help you know the best schedule to follow. If you’re not sure, err on the side of protection.

What Corpus Christi Automotive Service Consumers Should Know

December 23rd, 2009 by hardcastle50

There are some things Portland consumers should know about Corpus Christi automotive service and repair. First and foremost, Dub’s Garage cares about you and your family’s safety. And we really appreciate your business. Dub’s Garage in Corpus Christi wants to build a trusting relationship that becomes the foundation for a mutually beneficial experience for years to come.

Building on that foundation, there are some things that would help you understand the auto service and repair business better. First, it can be really hard to fix cars. The days of shade tree mechanics are long gone. The majority of automotive systems are computerized. It takes a lot of training and very expensive equipment to diagnose and repair modern vehicles. The technicians that work for Dub’s Garage need extensive computer training – not just how to run the diagnostic systems, but also searching for the right parts, networking with other technicians to help them with a difficult problem and pulling together a job order that makes sure that each step of the process is addressed.

The threshold for getting started as a technician gets higher all the time and there is a huge commitment to on-going training every year. This training takes time and money. It contributes to business overhead. The average Corpus Christi or Ingleside driver may not realize the business and environmental regulations Dub’s Garage must comply with. Of course that costs money too. Like any business, overhead is a big factor.

When you go into a Portland restaurant you don’t value the meal by what the food would cost at the grocery store. The restaurant has rent, wages, insurance, taxes, utilities, professional fees, equipment, supplies – you get the picture. The restaurant has to charge enough to not only pay for the ingredients, but for all these other things as well while making enough profit to remain in business. If you value the meal and are satisfied with your dining experience, you’ll come back and tell your friends.

It’s the same for Dub’s Garage. The value of its service is not the cost of the parts they replace, but in your satisfaction with the results. If they deliver a good product at a fair price, Corpus Christi customers are happy to see them succeed as a TX automotive business.

Contact Dub’s Garage to learn more about our extensive auto service training.

Or call us at 361-852-7379

Your Corpus Christi service center loves to see its customers whenever they come in, but they would much rather see them three or four times a year for routine maintenance than once a year on a tow truck. They want to work together with you to avoid breakdowns. Tell your Portland area friends and family to go in for their scheduled maintenance too. That lowers the service center’s marketing costs and helps keep its labor rates down. That’s good for everyone.

Dub’s Garage appreciates this great review of automotive service from AutoNetTV.

Timing Belt Replacement in Corpus Christi

December 16th, 2009 by hardcastle50

Today we want to talk about timing belts. They’re something that many Corpus Christi drivers don’t know much about and yet your vehicle won’t run if it’s broken – and it could cause many thousands of dollars damage if it does break. A broken timing belt is usually a tale of woe. Even though timing belt replacement is scheduled in the owner’s manual, it’s not the kind of thing that most Portland car owners remember because it’s not well understood.

Let’s review what a timing belt does. As you know, the engine’s power is generated in the cylinders. A piston rides up and down in the cylinder. During the first down stroke, an intake valve at the top of the cylinder opens and air and fuel is drawn into the cylinder. Then the piston returns to the top, compressing the fuel and air mix. At the top, the spark plug fires, igniting the fuel pushing the piston down in the power stroke. As the piston once again returns up in the final stroke of the cycle, an exhaust valve opens at the top of the cylinder and the exhaust is pushed out. The timing belt is what coordinates the opening and closing of the intake and exhaust valves. It’s called a timing belt because the valves have to open and close at just the right time.

Now, not all Corpus Christi and Ingleside vehicles have timing belts. Some have timing chains. Like the name implies, they use a chain rather than a belt to perform the function. It used to be that most engines used timing chains, which are extremely durable. Manufacturers started using belts rather than chains to save money in the manufacturing process. So now we’re left with a component that can break. They sort of shifted the problem to us. There are two broad categories of engine design: interference and non-interference. If the timing belt on a non-interference engine breaks, the engine simply stops running. That could be very dangerous depending on where you are at the time, but it causes no internal engine damage.

Interference engines, on the other hand, will get real messed up when the timing belt breaks, because the valves will actually fall down into the path of the pistons. Things get chewed up when that happens and it’ll cost thousands to repair the engine.

So, what are the warning signs? Unfortunately, there really aren’t any. There aren’t tell-tale sounds. In some vehicles, a technician from Dub’s Garage may be able to see part of the belt for a visual inspection, but many have a cover that’s in the way. The reality is that if the belt slips even one notch, it might as well be broken for all the damage it’ll cause. There’s no middle ground.

So how can we avoid these problems? Simply replace the timing belt when your owner’s manual calls for it. It can be 60,000 miles; it might be 90,000 or 100,000 miles. The point is, if you have 60,000 or more miles, ask your Dub’s Garage service advisor right away if your manufacturer requires a timing belt replacement.

Or call us at 361-852-7379

Sometimes you can go quite a while without a failure, but we’ve seen them happen within a couple of oil changes of being due. It’s not worth the risk.

What does it cost to replace a timing belt in Ingleside or Chapman Ranch? Well, that really depends on what kind of car you have. I can tell you that it’s usually not very easy to get to the timing belt – you often have to remove some accessories to get at it. It isn’t a cheap procedure, but it’s a fraction of what it could cost to repair the damage caused by a failure.

At Dub’s Garage we’re all about trying to prevent costly repairs, keeping you and your passengers safe and increasing your driving enjoyment. Thanks to AutoNetTV for their great auto video tips.

What To Do In Case Of An Accident in Portland

December 8th, 2009 by hardcastle50

Screeching tires, crunching metal – it’s an accident! If you’ve ever been in a car accident in Portland, even a minor one, you know how upsetting it can be. It’s hard to think straight and know what to do.

Let’s review what you should do in case of an accident:

When an accident occurs, you should always stop. Leaving the scene of an accident in Corpus Christi is considered a crime – even if it’s not your fault. And hit and run penalties are fairly severe, possibly resulting in steep fines, loss of your TX driver’s license or even jail time.

Your jurisdiction may require that you try to help someone who is injured by calling for help or performing first aid if you are able. Warn other Ingleside and Chapman Ranch motorists by putting out flares, using your flashers or lifting your hood. Call Portland emergency services as soon as possible. Tell the operator if medical or fire help is needed.

Always file a Corpus Christi police report. It’s tempting to skip this if everything seems to be ok. But without a police report, the other guy can say whatever he wants about the accident later, and you’ll not have an objective report to help defend yourself. Discuss the accident only with the police. Emotions are strong after an accident and we naturally want to talk about it – don’t. Never admit fault or guilt to anyone including the police officer. Sometimes we may feel at fault, but in the eyes of the law, the other guy is responsible.

Truthfully give the officer the facts: such as “I was going thirty miles an hour” not “I wasn’t speeding”. Remember, anything you say to the officer or anyone else can be used against you.

Also get the officer’s name and ID number and ask where you can get a copy of the accident report.

Get the facts on the driver and owner of the other vehicle:

  • Name
  • Address
  • Phone number
  • Date of birth
  • Driver’s license number and expiration
  • Insurance information

Also take down a description of the other Corpus Christi vehicle, license plate and vehicle identification number. Most TX auto insurance companies don’t record license plate numbers, so the VIN number is the best way to track the vehicle.

Ask witnesses, including passengers, to wait for the police. If they can’t wait, ask for contact information and request that they write a brief description of what they saw. If someone refuses to leave their name, write down their license plate number so the police can track them down later if necessary. Always call your insurance agent or your insurance company. Call or see a physician if you think you may have been injured. For vehicle repairs, call Dub’s Garage at 361-852-7379

Recommended Service Intervals

December 4th, 2009 by hardcastle50

Everyone in Corpus Christi knows we’re supposed to go to the dentist twice a year. We get our teeth cleaned and have a thorough dental inspection. Once a year, we get x-rays to look for problems that can’t be seen with the naked eye. When the dentist is done, he tells us what he’s found – “Everything’s fine, see you in six months.” Or “You’ve got a small cavity starting, let’s schedule an appointment to take care of it.” By the time you leave, you have a plan for addressing any necessary repairs.

This system works so much better than waiting for a painful problem before going into the dentist. Small problems are fixed before they turn into big problems. And you avoid those huge bills.

If we buy into this way of handling our dental care, why do we resist so much when facing the same system for our car care?

Following the manufacturer’s recommended intervals can be confusing. First there are recommendations for so many things: oil changes, transmission, coolant, air conditioning, power steering, brakes, fuel system, filters, belts, hoses, alignment, rotation, balancing …you get the point.

Every item has a recommended interval and it’s hard to keep it all straight – even if you’re part of the one percent of the population that reads your owners’ manual.

And if you have more than one sports car, the complexity is multiplied. You’d need a computer to keep track of everything. We’ll, that’s how Dub’s Garage does it. We subscribe to automotive databases that have your vehicle’s recommended intervals. You may have wondered how we know what else to recommend when you bring your car in for an oil change at our Corpus Christi location – it’s all in the computer.

Well, it’s not all in the computer. There are other variables that can’t be accounted for in the schedule. Things like the weather conditions, altitude, and driving conditions in the Corpus Christi area to be taken into account. Talk about these things with your Corpus Christi service advisor at Dub’s Garage and you may decide that the severe service schedule in your owner’s manual is more appropriate.

Since anything that’s not highway driving in moderate weather is considered severe, most of us in Corpus Christi do at least some of that and it should be taken into consideration.

Let’s take your basic oil change as an example – what issues are involved? The oil you put in your car is a blend of base oil and special additives. There are detergents to clean the inside of your engine and corrosion inhibitors. A good quality motor oil will not only lubricate your engine, it will help it stay clean inside and run cooler.

Now, these additives deplete with use and time. That’s why most maintenance recommendations include both a time and mileage element – like three months or 3,000 miles, whichever comes first.

It’s easy to think, “Gee, I’ve only driven 2,000 miles in the last three months. I can wait on that oil change.” But you need to remember that the inside of your engine is a harsh environment. The oil is contaminated with combustion by-products that start degrading its effectiveness even when it’s just sitting there.

A lot of people in Corpus Christi don’t realize the harm that can be done by just skipping a single oil change. There are a lot of metal parts moving around in your engine. Small bits of metal wear off and are floating around in your oil. They can be carried to more delicate areas of the engine where they cause damage. Your oil filter is designed to trap metal particles and other dirt, but if it’s clogged up because you haven’t changed it, it can’t trap any more.

Oil sludge is another problem. Sludge is oil that has turned to a gunky jelly – think Vaseline. Obviously, sludge doesn’t lubricate. It can also clog small oil passages so that all the parts don’t get properly protected by the oil. That’ll lead to premature wear.

If you’ve missed some oil changes, don’t despair. Just talk with your Dub’s Garage service advisor. Fess up – you’ll feel better. And he can help you get back on track. Following recommended intervals is the key to keeping your car on the road and avoiding major repairs.
