The price of gas has got everyone talking. It seems that people who need a bigger vehicle to carry family and gear, or provide four wheel drive, are especially hit 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. People 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 is to drive slower - but only when it's safe. Sometimes on the highway we drive an extra five ... ten . . . twenty ... over the speed limit. We do it to save time, but it only sav ... read more

The function of the fuel filter is pretty self-explanatory. It filters your fuel. The fuel filter is in the fuel line somewhere in between the fuel tank and the engine. Both gas and diesel vehicles around San Diego CA use fuel filters. Generally speaking there's not a lot of dirt in our San Diego CA auto fuel supply, but there is enough that you want to screen it out. The problem actually gets worse the older your vehicle becomes. That's because dirt, rust and other contaminants will settle out of the fuel and onto the bottom of the fuel tank. After your sedan is five years or older, it can actually have a fair amount of sediment built up. That just means that the fuel filter has to work harder as your sedan ages. It'll get clogged sooner and need to be replaced more often. A symptom of a clogged fuel filter is that the engine sputters at highway speeds or under hard acceleration. That's because enough fuel is getting through around town, but when you need more fuel for speed, enough ... read more

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 ... read more

Is your car sometimes hard to start? When you turn the key, does it hesitate or stutter? If so, the problem could be the result of a dirty fuel system. Your car's fuel system starts with the car 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 of today's cars 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 CA drivers are interested in buying fuel system cleaners that you can pour into your 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 ... read more

The last new car sold with a carburetor in North America rolled out of the dealership in 1990. Since then, all new vehicles 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 injection is a much more precise way of delivering fuel than carburetors. That translates into better fuel economy and power. 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 auto makers have introduced gas direct injection systems on some engines recently. These systems inject the gas directly into the cylinders under very high pressure - hundreds of times the pressure of port injection syst ... read more

The government mandates a lot of equipment on cars: emission devices and control computers; safety equipment like airbags; and crash worthiness requirements. All of this is great for the motoring public, but it does add quite a bit to the price of a new car. Because new cars are more expensive, CA drivers are using their old cars longer. The average car is now over nine years old. 68% of vehicles on the road have more than 75,000 miles/120,000 kilometers. 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 going. Some owner's manuals don't specify higher mileage service requirements. That doesn't mean it doesn't have to be done. In fact, it's more important than ever to stay on top of routine car maintenance for vehicles with more than 120,000 miles/190,000 kilometers. Just extend regular serv ... read more

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 Convoy Auto Repair. They have the tools and chemicals to do the job right. Convoy can remove particles, gum and varnish from your fuel system and get those injectors running cleanly and efficiently. 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 car maintenance ... read more

You would never like to drink a glass of mud, right? Well, your car 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 car will still run. But, then the contaminated fuel can plug your fuel injectors and allow damaging particles into your engine. A car with a partially clogged fuel filter might run well around town, but sputter and strain on the highway 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 and the gas you buy. If you drive a lot on dirt or gravel roads in rural CA, your fuel filter will have a harder time keeping the fuel clean. And, we hate to say it, but buyi ... read more

No one near San Diego, CA likes high fuel prices. But if one good thing has come about, it’s that people are really focused on how to reduce their fuel consumption. North Americans literally drive billions of miles less each month during times of high fuel prices. But we still need to drive, so it makes sense to try and increase our fuel economy however we can. Let’s look at a real life example of one of our AutoNetTV producers. He 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 value and breather element. He also made sure his tires were up to the recomm ... read more
