Maintenance Free Myth

Sometimes we hear people say, "What's up with all this maintenance stuff? Modern cars just don't break down." While it is true that today's cars and trucks are extremely reliable, they are also becoming increasingly complicated and use more exotic materials than ever before. All that complexity demands higher tolerances for everything. For example, most folks don't realize how high tech automotive fluids have become. Fluids like, engine oil, transmission fluid, coolant and brake fluid. Did you know that a modern engine would not run for more than a few months using motor oil formulas from 30 years ago? Today's automotive fluids contain a much higher percentage of additives to protect your vehicle's components from premature wear and corrosion. Time and miles march on for all of our cars. Please don't think we're using scare tactics to get you to take care of your maintenance - but here are some personal stories from ... read more

How Your Check Engine Light Works

Have you ever had an experience like this in Pleasanton California? You drive through the one of those automatic car washes. When you get to the end, where the dryer is blowing, your check engine light started flashing! You fear the worst, but within a block or two, the light stopped flashing, but stayed on. By the next day, the light was off. You wonder; "What was going on?" Well, it's actually a good lesson in how the Check Engine light works. Your air intake system has a sensor that measures how much air is coming through it. When you went under the high-speed dryer, all that air was blasting past the sensor. Your engine computer was saying, there shouldn't be that much air when the engine is just idling. Something's wrong. Whatever's wrong could cause some serious engine damage. Warning, warning! It flashes the check engine light, to alert you to take immediate action. It stopped flashing because once you were out from under t ... read more

Alternative Fuel Vehicles In Pleasanton California

Let's talk about alternative fuel vehicles. In their quest to reduce the use of fossil fuels and harmful exhaust emissions to our Pleasanton environment, automakers will have a number of alternatives for us very soon. For instance, Flex Fuel vehicles are already available in the Pleasanton area. Flex Fuel vehicles can run on gasoline or on E85 fuel. E85 is a mixture of 85 percent ethanol and 15 percent gasoline. The ethanol is made from corn. The benefits are in using less petroleum and reduced pollution. The drawbacks are that E85 gets lower fuel economy and that when gas prices are low, E85 can be more expensive than straight gasoline. You should only use E85 if you have a Flex Fuel compatible engine. Flex Fuel vehicles have special seals and gaskets that can stand up to the high alcohol content of E85. Using E85 in a regular engine can lead to gas leaks and fires. Diesel engines have been around the Pleasanton area for a long, long time. Modern ... read more

Fuel Saving Tip: Fuel System Cleaning Near San Ramon California

A lot of gas is wasted in the San Ramon area by dirty fuel delivery systems. Let's start at the tank. The gas tank gathers dirt, rust and sediment over the years. That's why there's a fuel filter to clean the fuel after it leaves the tank. A dirty filter will rob the engine of the clean gas it needs to run efficiently. The fuel intake components get coated with gum and varnish over time. This results in fuel being delivered inefficiently and some of that gunk getting into the engine. A fuel system service at Precision Auto Repair will leave your intake as clean as a whistle. The big fuel thief is dirty fuel injectors. They deliver fuel to the engine at a specified pressure and in a particular spray pattern. When they're clogged, the fuel doesn't get atomized the way it's supposed to and doesn't get burned as efficiently ... read more
