Pleasanton Auto Repair

This fuel saving tip is so simple, no one from here to San Ramon will believe it. It has to do with your gas cap. The first thing is to make sure it's screwed on tight. If it's loose, gas vapor will be constantly leaking out; wasted gas. And air will get in and that can cause your oxygen sensor to read incorrectly and the oxygen sensor will tell the engine management computer to adjust the fuel-air mix and, well, you get the picture; you'll be burning more gas around San Ramon than you need to. This could cause the check engine light to come on as well. A worn gas cap can have the same effect. If you constantly smell gas when you walk by your tank, you might need a new gas cap. So, twist your cap until it clicks three times – that means it's on tight. Have your San Ramon area service advisor at Precision Auto Repair inspect the cap to see if it needs to be replaced. See, I told y ... read more

Today's Precision Auto Repair auto maintenance article focuses on your serpentine belt. Your serpentine belt is a long belt that’s driven by your engine. It winds around several accessories that power important automotive systems. Let’s go over them. First, the serpentine belt drives your Honda, Acura, Toyota or Lexus air conditioning system. It spins the compressor that makes the cool air that takes the edge off the summer heat in Pleasanton. Next, the belt powers the alternator. The alternator creates electricity that’s used by your Honda, Acura, Toyota or Lexus’s electrical systems and also charges your car battery. All Pleasanton drivers know that without the alternator, the battery will go dead in a few miles. The serpentine belt may also run the pumps for both the power steering and power brakes. And, on many Honda, Acura, Toyot ... read more

Did you know that most of the cars driving around Pleasanton California carry more computer power than the Apollo 121 Lunar Module that landed on the moon in 1969? New cars sold in the Pleasanton area have as many as twelve networked computers and over five miles (eight kilometers) of wiring. In fact, for the last decade or so, auto computers have been controlling about 85 percent of your vehicle's functions. Cars have sensors for manifold air temperature, coolant temperature, manifold air pressure, airflow, throttle position, vehicle speed and oxygen content. All of this electronic wizardry is pretty complicated. So how do you know when there is a problem? It's simple; the Check Engine light comes on. The computer monitors all the sensors and uses that information to decide what to adjust such as the fuel mix, spark timing and idle speed. In addition, the computer monitors its own circuits. When it finds a fault, it ... read more

We find that a lot of Pleasanton service and repair at Precision Auto Repair are a little tentative when they talk with their automotive advisors. They want to ask questions, but don't want to be embarrassed or to seem pushy. Cars are very complicated and there's more to know about them than most of us have the time to learn. Maybe it's because cars have become so much more reliable that the average person just doesn't need to know as much to keep their vehicle on the road. You know, your local hospital has a Patient's Bill of Rights that they post throughout the hospital. We think our Pleasanton automotive service customers also have a right to ask any question they need to understand what is wrong with their car and what it will take to fix it. They need to feel free to ask the cost and benefits of recommended services. And they certainly have a right to understand the financial end of the transaction ... read more

One of the most popular vehicle modifications in California is custom wheels and tires. Custom wheels help you stand out from the crowd without spending a lot of money, and custom tires can help you fine tune your performance. Not that long ago, new cars came with just one or two tire and wheel options. Now manufacturers are offering more choices and over a third of new vehicle buyers choose custom wheels. That seems to have fueled public demand for custom wheels in all vehicle categories. The available styles, colors and finishes are endless. You're sure to get the look you want - from sleek and stylish to tough and aggressive. While custom wheels are largely a matter of taste, custom tires are a matter of function. That is not to say that there are not a lot of cool looking tires out there, it's just that tires are vital to your safety, so there are some important practical considerations.

At Precision 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 ... read more

Your car might have an alignment problem if: it drifts or pulls to one side, your steering wheel is off center, you have uneven tire wear or your car doesn’t feel like it handles right. When all of a vehicle’s wheels are lined up exactly with each other, your wheels are in alignment. Running into potholes, smacking a curb or other object are great ways to knock your car out of alignment. Then one or more of your wheels starts pulling in a slightly different direction and the problems begin. Driving for an extended time when you're out of alignment causes your tires to wear unevenly and excessively. This can be dangerous and expensive. You'll have to replace your tires sooner, but even worse - you may cause premature wear to your suspension system, which can be really expensive. The front wheel alignment is adjustable on all vehicles, and the back wheels are also adjustable on some cars. The adjustment can go three different ways. The first adjustment ... read more

If you aren’t currently using synthetic motor oil in your Pleasanton vehicle, maybe now’s the time to consider it. Need more information? Well, synthetic motor oil is a substitute for petroleum based oil. Synthetic oil doesn’t gel or gum-up like petroleum based oil and it doesn’t vaporize as easily. It protects better in severe driving conditions like stop and go driving around Pleasanton, as well as in very hot or very cold conditions. More and more new vehicles are being delivered with full synthetic motor oil; with the recommendation to use synthetic for the life of the vehicle. Why is this? Synthetic motor oil maximizes engine power and fuel economy. To see why; we’d need a microscope, so we’ll have to settle for using our imaginations. The molecules of conventional motor oil are long hydrocarbon chains. Synthetic motor oil, on the other hand, has uniform, round molecules. Which is more slippery ... read more
