Stuart Terry Auto Repair

At Stuart Terry Auto Repair 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 California 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 California.

You may ask, why has it taken so long getting to California and North America? There are a bunch of reasons like fuel tax policies and such, but the biggest hurtle was that California 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 California 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 California 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 California, 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.

You may have found yourself in the following situation: You go to get your oil changed and the service adviser recommends you get a new engine air filter. You say yes, but because you didn’t know what an air filter is or what it does, you were too embarrassed to ask.

First of all, you did the right thing by getting a new one. And, you should never be too embarrassed to ask for more information. It’s your money and you have a right to understand what you’re paying for. Let’s review what an air filter does.

Air is the focus of this discussion. What is the air like outside right now? Can you see the smog? Is it full of pollen? How about dust? Anyone with hay fever can tell you that there’s plenty in the air that you can’t see. Well, it’s the engine air filter’s job to clean that air before it goes into your engine, to mix with the fuel and be burned. Without a filter, the inside of your engine would be extremely dirty from all the gunk that was burned in the cylinders.

In fact, for every gallon of gas you burn, your engine needs 12,000 gallons of air. That little filter does a very big job. It’s no wonder that the air filter gets dirty and needs to be replaced. Think about a vacuum cleaner. When the bag gets full of dust and dirt, the vacuum doesn’t clean as well. It can’t move enough air to create good suction. A clogged engine air filter is the same way – the engine can’t get enough air to burn the fuel efficiently. That means less power and wasted gas.

That’s why your manufacturer has recommended that you change your filter at regular intervals. Of course the conditions you drive in will affect how quickly the filter gets dirty. If you drive where it’s very dusty or where there’s lots of pollen or pollution, you may need to change the filter sooner. The filter is easy to check visually, so your service technician can quickly make the call. He might recommend immediate replacement, or simply let you know that it is getting close and that you’ll need to replace it soon – like at your next oil change.

Because a severely dirty air filter hurts your fuel economy, many people find that a new air filter pays for itself in gas savings before the next oil change. They also make premium air filters that have been proven to increase your horsepower and torque. If more power is important to you, a high performance air filter is some of the cheapest horsepower you can buy.

The better your car breathes, the better it runs – kind of like people. And don’t worry – if you have a question or don’t understand a recommendation just contact Stuart Terry Auto Repair at 619-287-9626 or http://www.ascca24.com/stuart/contact.htm

Getting enough fuel to your engine is very important for performance, fuel economy and safety. In order to accomplish this, your fuel system needs to be clean.

Today’s production cars have fuel injectors, rather than a carburetor. The injectors need to be cleaned from time to time in order to deliver the fuel with the correct pressure, spray pattern and volume.

You can buy fuel system cleaners that you just pour into your gas tank that can help maintain an already clean fuel system, but can’t do a major cleaning. For that, you need to see Stuart Terry Auto Repair. They have the tools and chemicals to do the job right. Stuart Terry Auto Repair can remove particles, gum and varnish from your fuel system and get those injectors running cleanly and efficiently.

You’ll find Stuart Terry Auto Repair at 4858 El Cajon Blvd. in San Diego, California 92115. Or just give us a call at 619-287-9626 to schedule an appointment.

You’ll enjoy more power, better gas mileage and reduced exhaust emissions. The cleaners also help prevent rust and corrosion in your fuel system and lubricate vital engine parts.

And, as with all maintenance, it can help prevent costly repairs that can happen because you didn’t take preventative steps. Check with your service technician at Stuart Terry Auto Repair and see when your car is scheduled for a fuel system cleaning.
