Ever notice that your tire is covered with writing? It's like some hieroglyphic art form. Of course, Centennial drivers know that it's not just graffiti, but to most of us, it might as well be. Would you like to know what all those codes on your tire mean? It won't lead you to buried treasure, but it could help you make a better tire purchase at your local Centennial tire store.Prominently featured on your tire is a set of numbers and letters that looks something like this: 225 50 R 16 92 H. The first number is the width of the tire in millimeters, or the width between the sidewalls of the tire when it is fully inflated and not carrying a load. When Centennial drivers replace tires, they need to match this width number, or the tires won't fit properly in the wheel wells.The 50 is the aspect ratio of the tire, which is measured by taking the height of the sidewalls and dividing it by the tread width. If you drive off-road around the Centennial area, it should have a high aspect ratio. F ... read more

Hello Colorado! Today's vehicle care topic is: Synthetic Oil vs. Petroleum Based Oil. Synthetic motor oil is a substitute for petroleum based oil. If you aren't currently using it, why not? Synthetic motor oil maximizes engine power and fuel economy. To see why, we'd need a microscope, so we'll have to settle for using our imaginations. The molecules of conventional motor oil are long hydrocarbon chains. Synthetic motor oil, on the other hand, has uniform, round molecules. Which is slipperier, a pile of pencils or a pile of marbles?Synthetic motor oil lubricates better because there's less friction. This results in myriad benefits: better wear protection, cooler operating temperatures, more power and better fuel economy. And synthetic oil doesn't sludge up like conventional oil so it prevents those small oil passages from clogging up. (We see that too often at Davis Automotive Repair in Centennial.)Some manufacturers are extend ... read more

When we Centennial residents get a car repair bill, we really shouldn't be surprised to find “diagnostic fees” as one of the line items. When we get a computer fixed, there is usually a charge for the time it takes to diagnose the problem. When we go to a medical doctor, most of his fee is for his ability to diagnose what's wrong. It's no different with our vehicles.Some diagnoses are fairly simple. Brake repairs at Davis Automotive Repair usually require only a visual inspection, for instance. But other problems are much more difficult to diagnose. An intermittent engine problem, for example, takes time and expertise to pinpoint.Modern vehicles have multiple computers that monitor a variety of sensors throughout the vehicle. When one of those sensors has a reading that is higher or lower than the standard parameters, the computer turns on the Check Engine light. Technicians at a service center such as Davis Automotive Repair in Centennial can scan the engine's computer for ... read more
