No one in Centennial, Colorado, likes to spend a chunk of change at the gas pump. Rising Colorado fuel prices, however, have spurred Centennial 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 ... read more

Getting adequate 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.Centennial drivers can buy fuel system cleaners that you pour into your gas tank to help maintain an already clean fuel system; however, they can't do a major cleaning. For that, you need to see Davis Automotive Repair in Centennial. We have the tools and chemicals to do the job right. Our friendly and knowledgeable team at Davis Automotive Repair can remove particles, gum and varnish from your fuel system and get those injectors running cleanly and efficiently. You'll find Davis Automotive Repair at 6867 South Emporia Street in Centennial, Colorado 80112. Or just give us a call at 303-790-4789 to schedule an appointment. You'll ... read more

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.Centennial 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. Cen ... read more

No matter how well they're made, vehicles in Centennial, Colorado, will have design or manufacturing problems. And when the government thinks a problem is really serious for people in Centennial, Colorado, they require the manufacturer to issue a recall notice and fix the vehicle  free of charge. The manufacturer then tries to contact everyone in Colorado who owns that type of vehicle to get the recall work done. Perhaps you have received a postcard notifying you of a recall.

There's CarFax, AutoByTel and the DMV.Recalls are serious but not all that common. Sometimes there are fewer issues, and for these, manufacturers issue a Technical Service Bulletin, or TSB, that tells service centers like Davis Automotive Repair how to repair a frequent or difficult problem.The pros get ... read more

The price of gas in Colorado has got people in Centennial talking. It seems that Centennial folks who need a bigger vehicle to carry family and gear, or provide four wheel drive, are hit especially 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 around Colorado. People in Centennial 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 Centennial drivers can do is drive more slowly - but only when it's safe. Sometimes on the freeway we d ... read more

Centennial residents know that engines burn fuel to operate. Fuel is pumped from your fuel tank to your 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—and 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 engine.Direct injection engines burn fuel more efficiently than conventional 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 . The turbocharged version delivers 350 horsepower.Why the big difference in power? Direct ... read more

Something you're going to be hearing a lot about around Centennial, Colorado, is diesel engines. We're not talking about semi-trucks and buses; we're talking about diesel engine cars, pick-ups and SUVs.Most people in Colorado are surprised to learn that around half the cars on the road in Europe have diesel engines. Nearly all import brands offer a range of diesel engines abroad – even the ultra-luxury brands like Mercedes and BMW. For the most part, these diesel engines haven't been available in Centennial, Colorado. But that's about to change.In the past, North American diesel fuel has had a much higher sulfur content than European fuel. Recent environmental laws have required changes in diesel formulation and emissions standards here in Centennial, Colorado, so we are now ready to start seeing more diesel options offered over the next few years.Why are so many Centennial drivers interested in diesel engines? Well first off, diesel fuel is more energy dense. Th ... read more

Diesel engines have been used extensively in Europe and Asia for many years. They haven't been as common in the Centennial area because of the high sulfur content in our diesel fuel. But the government is now mandating lower sulfur content and, as a result, we are going to see more Centennial diesel-fueled vehicles on the road, especially in passenger cars and SUV's.Diesels are popular in Colorado because they get better fuel economy than gas-powered engines. They also last longer. Modern diesel engines are quiet and powerful. And if you associate diesel engines with black smoke, then you're not up with the times. That smoke is a thing of the past.Diesels don't produce any more pollutants than gasoline engines. The pollution standards for diesel-powered vehicles are as strict in Colorado as for other vehicles.Also, diesel engines can run on bio-diesel fuels as well as fossil fuels. Diesel fuel can be produced from vegetable oil or from ... read more

Centennial residents often ask the question: "Will using premium gas make my car run better?" The answer is simple. But first, let's talk about what exactly premium gasoline is.Different grades of gasoline have different octane ratings. Regular gasoline has the lowest octane rating and premium the highest. Most gas stations around Centennial, Colorado, also carry a mid-grade that falls in between the two. The octane range for the different grades of gas varies by region due to altitude differences.Engines require different octane ratings because of design differences. For example, turbocharged engines usually require premium gas.There's a sticker on your gas tank filler lid that tells you the minimum octane rating your vehicle manufacturer recommends.
