Today at Davis Repair we want to talk with you about a very important safety issue. This automotive safety warning is coming from a very unusual source: fire fighting experts. You’ve probably heard of E-85 gasoline being offered in the Denver area. Some newer vehicle models are specifically built to run on E-85 – the rest are not. E-85 gasoline has been developed to fight air pollution and reduce oil consumption. E-85 fuel is a mix of 85% ethanol, a grain-base alcohol, and 15% gasoline. So-called Flex-Fuel vehicles are designed to use either normal gasoline or E-85 gas. The result is lower harmful exhaust emissions to our local Denver community. All gas engines can run with up to 10% ethanol and in fact a lot of gasoline sold in the Centennial Colorado area does contain some ethanol.

New cars sold in the Denver area have as many as twelve networked computers and over five miles (eight kilometers) of wiring. In fact, for the last decade or so, auto computers have been controlling about 85 percent of your vehicle’s functions. Cars have sensors for manifold air temperature, coolant temperature, manifold air pressure, airflow, throttle position, vehicle speed and oxygen content. All of this electronic wizardry is pretty complicated. So how do you know when there is a problem? It’s simple; the Check Engine light comes on. The computer monitors all the sensors and uses that information to decide what to adjust such as the fuel mix, spark timing and idle speed. In addition, the computer monitors its own circuits. When it finds a fault, it turns on t ... read more
