Ethanol based fuels are common place in the automotive world and since ethanol is a renewable resource and a cleaner burning alternative to gasoline, ethanol, or mores specifically ethanol blends, have become a popular choice in many countries. Pure ethanol or E100 isn’t typically used as a fuel since its lack of volatility (compared to gasoline) can make it hard to start when the engine is cold. The most common blend we are used to is referred to as E85, consisting of 85% ethanol and 15% unleaded gasoline.
