How Do You Save Gas in San Diego, CA?

No one in San Diego, CA, likes to spend a chunk of change at the gas pump. Rising CA fuel prices, however, have spurred San Diego drivers to focus on how to improve their fuel economy. North Americans literally drive billions of miles/kilometers less each month during times of high fuel prices. But we still need to drive (we love our vehicles, after all!), so it makes sense to try and increase our fuel economy however we can.Let's look at a real life example. This man has one of those really big SUVs. Lots of kids and horses to haul around, you know. His family was planning a four day camping trip. Here's what he did to cut his fuel costs:First, he installed a new, high flow engine air filter. Then he had his service center change his oil, flush his cooling system and service his front and rear differentials along with the transfer case. He also had a fuel system cleaning, replaced his PCV valve and breather element. He also made sure his tires were up ... read more

Fuel Filter Replacement

Hello San Diego resident! You would never like to drink a glass of mud, right? Well, your vehicle feels the same way. It needs a steady supply of clean fuel in order to run well and deliver good fuel economy. The fuel filter's job is to clean dirt and rust out of the fuel before it gets to your engine. A clogged fuel filter can actually choke off the engine so that it won't start or run. Some fuel filters have a bypass valve that allows fuel to go around the clogged filter so your vehicle will still run. But, then the contaminated fuel can clog your fuel injectors and allow particles into your engine.A vehicle with a partially clogged fuel filter might run well around San Diego, but sputter and strain on the because it's starving for gas. There are two things that affect how often you need to replace the filter. They are: where you drive in CA and the gas you buy. If you drive a lot on dirt or gravel roads in rural CA, your f ... read more

Clean Fuel ? Clean Performance for San Diego Drivers

Fuel filters clean the dirt, dust and debris out of your fuel. Both gasoline and diesel-powered engines have them. The fuel filter is located in the fuel line between the fuel tank and the vehicle engine.San Diego auto owners don't need to filter their fuel because it has lots of grit in it; they need to filter it because it has some grit it in. Any dirt is bad for your engine. The cleaner the fuel, the better your vehicle engine will run.Over time, the small amounts of rust, dirt and contaminants in your fuel settle out inside the fuel tank. After about five years, this can amount to a quite a bit of sediment. This means that as your vehicle ages, your fuel filter has to work harder to screen your fuel: more sediment in your tank means more potential for grit in your fuel.The harder your fuel filter works, the more often it needs to be replaced. Check with your owner's manual to find out how often it should be serviced and how long you can expect it to last. San ... read more

Fuel Injectors

The last new American vehicles sold in San Diego with a carburetor rolled out of the CA dealerships in 1990. Since then, all new vehicles here in San Diego, and nationally, have had fuel injectors. In very simple terms, a fuel injector is a valve that squirts fuel into your engine. Your engine control computer tells the fuel injector how much gas to deliver as well as the precise time it should be delivered. Of course this happens thousands of times a minute. Fuel injectors deliver fuel far more precisely than carburetors. That translates into better fuel economy and more power for San Diego drivers. Virtually all fuel injectors for gas engines are known as port fuel injectors because they deliver the fuel to a port just outside the cylinder. Port fuel injectors operate at about 40 to 80 pounds per square inch of pressure.A few vehicle manufacturers have introduced gas direct injection systems on some engines recently. These systems inject the gas ... read more

Some deliver the power of a V8 with the economy of a V6.For example, in one family of engines the conventional V6 makes about 250 horsepower. The direct injection version of the same engine makes over 300 horsepower and gets essentially the same fuel economy. The turbocharged version makes over 350 horsepower.So what are the differences from a conventional engine?The core difference is in the fuel injection system.
