E-85 Fuel Safety Advice From John’s Auto Care



Today at John’s Auto Care 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 Eldorado Springs area. Some newer vehicle models are specifically built to run on E-85 – the rest are not.

Does your vehicle use E-85 gasoline? Bring it down to John’s Auto Care at 1900 55th St. #104 in Boulder, CO 80301 to find out, or give us a call to make an appointment by calling 303.442.2932.

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 Eldorado Springs community.

All gas engines can run with up to 10% ethanol and in fact a lot of gasoline sold in the Boulder, CO area does contain some ethanol. The problem comes when well meaning car owners without Flex Fuel certified vehicles put E-85 into the tank.

At a 15% concentration, the potential for problems arises. Because of the chemical differences between ethanol and gasoline, special seals and gaskets are needed for Flex Fuel vehicles in Boulder CO. In a normal engine, the ethanol in E-85 gas will eat away vital seals and gaskets. This leads to gas and oil leaks.

You Boulder drivers can imagine the fire hazard caused by leaking gasoline. CO fire fighting experts caution drivers to only use E-85 if they know they vehicle is certified to handle it. They expect vehicle fires to increase because of using the wrong fuel in non-Flex Fuel vehicles.

So are car owners who don’t have a Flex Fuel vehicle but use E-85 to help the environment actually putting themselves at risk? Yes. In fact, service and repair centers in Boulder, CO are being warned to purchase fire extinguishers that use the special foam needed to extinguish ethanol fires as a precaution in case starting-up an ethanol damaged engine leads to a fire.

Obviously, this isn’t something you want to have in your Boulder, CO garage at home, either. If you have a Flex-Fuel certified vehicle, feel free to protect the environment by using E-85 gasoline. If not – please do not use E-85 in an engine that’s designed to run on unleaded gasoline only. At John’s Auto Care we are concerned about your safety. If you have questions or want to find out how to determine if your vehicle can safely use E-85, go to www.e85fuel.com for more resources.
