A lot of us drivers are asking ourselves the same question lately: how can we save on fuel? Centennial area residents are all cutting back, if not in fuel consumption, then in other areas of our lives. Preventive Maintenance Preventive maintenance is an important way people in Centennial can conserve fuel by improving fuel economy. And one of the easiest and most effective ways to do that is to keep the oil in our vehicle adequate and clean.Oil lubricates your vehicle engine and keeps it running smoothly.

This all translates to lower fuel economy.Check your oil to make sure the engine is getting all it needs. Your owner's manual and service advisor at Davis Automotive Repair will tell you the proper weight and type of oil for your vehicle.

There's not much we can do about the price of gas in Centennial, Colorado, but we do quite a bit about how much we use as we're driving on our Centennial streets.Our driving habits can dramatically affect our fuel economy.The first thing we can do is watch the 'go-pedal.' Hard acceleration just sucks the gas. Gently leave stop lights and plan lane changes so you don't need to floor it. That can save you hundreds of dollars a year.Go a little slower on the freeway. Once you're going more than 65 miles an hour (105 kilometers per hour), your fuel economy starts to drop dramatically. Leave early so you don't need to rush to be on time. And cruise control is your friend – steady speed uses less gas.Plan errands ahead. Make fewer trips by combining errands.Hey at current gas prices, a lead-foot might as well be a gold foot.

The team at Davis Automotive Repair in Centennial, and Colorado car owners are all talking right now. Better gas mileage. Fewer emissions. Centennial drivers want to save the environment and their pocketbooks.And we all know—or should know—that preventive maintenance will help maximize fuel economy. But is there something more people in Centennial can do? After all, some of us folks can't cut back on our driving, and others would like to do more to economize.Weight is one major enemy of fuel economy. The more you lug around in your vehicle, the more fuel you have to burn to get from point A to point B. And that means buying more gas in Centennial and producing more emissions.Of course, your vehicle's weight isn't negotiable. And you can't do much about the weight of your passengers. And this isn't an article about diet and exercise.But look around your vehicle. Are you hauling a bunch of unnecessary weight around? Do you really need your golf club ... read more

Let's talk about alternative fuel vehicles. In their quest to reduce the use of fossil fuels and harmful exhaust emissions in our Colorado environment, automakers will have a number of alternatives for Centennial drivers very soon.For instance, Flex Fuel vehicles are already available in the Centennial 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 to Centennial drivers are in using less petroleum and reduced pollution. The drawbacks are that E85 gets lower gas mileage and when gas prices are low, E85 can be more than straight gasoline.Centennial drivers should only use E85 if they 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 C ... read more

Centennial residents know that engines need to burn fuel to operate. Fuel is pumped from your fuel tank to your vehicle engine where it is squirted—or injected—into your engine's cylinders. This is the function of the fuel injectors.There are two ways to inject fuel into an engine. Fuel needs air to burn, so in the first method, fuel is injected into a port and allowed to mix with air—before it is drawn into the cylinders. In the second method, fuel is injected directly into the cylinders and mixes with air after it enters the vehicle engine.Direct injection engines burn fuel more efficiently than conventional vehicle engines. Some models can deliver the power of a V8 with the economy of a V6.For example, in one family of engines, the conventional version (a V6) delivers about 250 horsepower. The direct injection version delivers over 300 horsepower and gets about the same gas mileage. The turbocharged version delivers 350 horsepower ... read more

There are a surprising number of small, inexpensive parts that can lead to expensive engine damage when they fail. It doesn't seem right.Fortunately a lot of those things can be taken care of in routine maintenance. They may not be easy to remember because it is a long list, but your service center at Davis Automotive Repair can help you know what's scheduled to be taken care of.Some of us in Centennial, Colorado, really don't look forward to going in for an oil change and then getting a list of the other things the manufacturer recommends.But automotive maintenance is all about prevention and addressing small problems before they get big.

The last new American vehicles sold in Centennial with a carburetor rolled out of the Colorado dealerships in 1990. Since then, all new vehicles here in Centennial, 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 Centennial 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 injec ... read more

It can even lead to costly repair bills for Centennial drivers. So keep your fuel system clean as part of your routine preventive maintenance.Fuel injectors have replaced carburetors in most of today's vehicles.
