Fuel

The AP09 Engine is designed to run on fuel that is a mixture of methanol, nitromethane, and lubricants. The oils mixed into the fuel provides all of the lubrication and most of the heat dissipation for the engine. Do not use fuel that has incorrect oil contents or is old and has been exposed to air and/ or moisture. The fuel used for break-in should have no more than 15% nitromethane and no less than 20% Oil content (made up of a mixture of castor or castor/ synthetic ).Once the engine is broken-in, a fuel containing 25-35% nitromethane can be used. Do NOT use a fuel that contains only synthetic lubricants. Fuels with some or all castor oil for the lubricant will make the engine run cooler and last longer.
