AGE-85 (Aviation Grade Ethanol) is a high-performance fuel that may be used in any piston engine aircraft. It contains approximately 85% ethanol, along with light hydrocarbons and biodiesel fuel. AGE-85 is specifically blended for cold starting and good mixture balance. AGE is unleaded, burns cleaner, has lower exhaust emissions and is more environmentally friendly than traditional aviation fuels. The ethanol in AGE-85 prevents carburetor and fuel line icing, and provides excellent detonation margins.
