What is E85

E85 is a blend of gasoline and ethanol. Generally the mixture is about 85% ethanol and 15% gasoline. The mixture does may vary because of the climate of your country. In colder climates you will have less e85 to assure a better cold start and running temperatures. 

The ethanol used in E85 is an alcohol-based fuel made by fermenting and distilling crops, corn mostly.

How does it work

If you have a gasoline powered car the only change we need to make is changing the mapping of the ECU. In simple terms, we have to change a few parameters in the computer which controls the engine. Once this is done, you can drive to a gas station that serves E85 fuel and fill your tank up. If, for some reason, you have to fill your tank with normal gasoline, this is no problem at all. The way we program the computer of the engine makes it so you can put 0 to 100% ethanol in your car. 

All cars with a gasoline engine are capable of running on E85. Generally cars that are older than 20 years old will also need new injectors and fuel lines.
