San Diego drivers know that underinflated tires wear out more quickly. Underinflation is also a major cause of tire failure for CA auto owners. More flats, blow outs, skids and longer stopping distances are all results of underinflated tires.It's hard for many San Diego drivers to tell when a radial tire is underinflated. If your owner’s manual recommends 35 pounds of pressure, your tire is considered significantly under-inflated at 26 pounds. The tire may not look low until it gets below 20 pounds.Uncle Sam to the rescue! A recent U.S. federal law required vehicle manufacturer’s to include a Tire Pressure Monitoring System - or TPMS system - in all vehicles. Many Canadian vehicles have them as well.  The system is a dashboard mounted warning light that goes off if one or more of the tires falls 25% below its pressure recommendations.Obviously, all of this doesn't come free for San Diego car owners.

The government mandates a lot of equipment on cars in San Diego, CA: emission devices and control computers, safety equipment like airbags and crash worthiness requirements. All of this is great for the San Diego motoring public, but it does add quite a bit to the price of a new vehicle.Because new vehicles are more expensive, people in the San Diego area are driving their old vehicles longer. The average vehicle is now over nine years old. Two thirds of vehicles on the road in CA have more than 75,000 miles (120,000 km) on them. As cars age, their performance drops, they have difficulty idling for long periods and are more sensitive to weather extremes. Fortunately today's cars are up to the challenge – but they need a little help to keep on goin'.Give John's Automotive Care a call at 619-280-9315 to schedule your next maintenance.Some owner's manuals don't specify service requirements at higher mileage.

Is your vehicle sometimes hard to start early in the morning? When you turn the key, does it hesitate or stutter? If so, the problem could be the result of a dirty fuel system. Your vehicle's fuel system starts with the air filter and ends in the top of your engine. Over time, different parts of the system get dirty, which robs you of performance and hurts your fuel economy. Most San Diego vehicles have fuel injectors, rather than a carburetor. Fuel injection systems have fewer problems and require less adjustment. But they still need to be properly maintained. This is why your owner's manual has a schedule for cleaning your fuel injectors and other parts of your fuel system.Some San Diego residents are interested in buying fuel system cleaners that they can pour into their gas tank. You can do that - and there are lots of great products available that can help maintain an already clean fuel system - but these products cannot do a major cleaning. For that, you need to see Joh ... read more

The price of gas in CA has got people in San Diego talking. It seems that San Diego folks who need a bigger vehicle to carry family and gear, or provide four wheel drive, are hit especially hard. That is why we thought it would be good to review some things that anyone can do to improve fuel economy. First let's start with how we drive around CA. People in San Diego may not realize that they can really save on gas by just changing a few driving habits. One of the biggest is jackrabbit starts - you know, flooring the gas as soon as the light turns green. That really wastes a lot of fuel. Building up your speed at a slower pace uses less fuel and is easier on your engine and drive train. And don't drive with one foot on the brake. That's also a drag on fuel economy, and it wears out your brakes faster, too. Another thing San Diego drivers can do is drive more slowly - but only when it's safe. Sometimes on the freeway we drive an extra f ... read more

With the recent focus in the San Diego area on improving fuel economy, we've been told how important it is to maintain our tire pressure.San Diego drivers know that tires wear out, but we want to make them last as long as possible because they're not cheap to replace. In addition to saving gas, properly inflated tires last longer. Underinflated tires will wear out more quickly.Some people in San Diego wonder if they should add a few extra pounds of pressure when they fill up their tires. Bad idea. In fact, there are very good reasons not to overinflate your tires. For one, the middle of the tread will wear unevenly because the full tread is not contacting the road properly. That also adversely affects your handling. Stop by John's Automotive Care to see about tire maintenance for your vehicle.

Since driving requirements and lifestyles differ among San Diego drivers, your vehicle manufacturer publishes two auto maintenance schedules: the regular schedule and the severe service schedule.

  Which item is most often stolen from vehicles in San Diego?Is it: Stereo Wheels Air Bag DVD System Well, if you said stereo – you used to be right.

Recalls are pretty serious for San Diego residents and don't happen all that often. But sometimes cars have less serious problems that San Diego residents still might want to know about. For these less serious cases, the vehicle manufacturer issues what is known as a Technical Service Bulletin – or TSB. These bulletins tell San Diego service centers (including John's Automotive Care) how to repair a problem that occurs frequently or is especially difficult.Your San Diego service center receives updated information through subscription plans, which are sometimes available in consumer versions too.Whatever your source, pay attention to San Diego vehicle recalls to keep you and your passengers safe. No matter how well they're made, vehicles are bound to have problems with their design or manufacturing. Think of all the moving parts. When the government thinks a problem is really serious, they require the vehicle manufacturer to issue recall notices to ... read more

Something you're going to be hearing a lot about around San Diego, CA, is diesel engines. We're not talking about semi-trucks and buses; we're talking about diesel engine cars, pick-ups and SUVs.Most people in CA are surprised to learn that around half the cars on the road in Europe have diesel engines. Nearly all import brands offer a range of diesel engines abroad – even the ultra-luxury brands like Mercedes and BMW. For the most part, these diesel engines haven't been available in San Diego, CA. But that's about to change.In the past, North American diesel fuel has had a much higher sulfur content than European fuel. Recent environmental laws have required changes in diesel formulation and emissions standards here in San Diego, CA, so we are now ready to start seeing more diesel options offered over the next few years.Why are so many San Diego drivers interested in diesel engines? Well first off, diesel fuel is more energy dense. There's more power in a barrel ... read more

One San Diego automotive service issue that doesn't get much attention is driveline service. Drivelines don't get talked about very much around San Diego, but they're very important. First let's define what the driveline is:Taking a small step back, the power plant is comprised of the engine and transmission. The driveline starts there and includes all of the components that transfer power from the transmission to the wheels.That's not really a lot of components, but they handle the full force of the engine. Without the driveline you're not moving. So San Diego residents need to take good care of it. The driveline components differ depending on whether your vehicle has front wheel drive, rear wheel drive, all wheel drive or four wheel drive. For purposes of our discussion, we're going to have to oversimplify a bit. If you are ready to have your drive train looked at, give us a call at 619-280-9315. Let's start with front wheel drive.
