Instructions
Decide what your priority is, whether car performance or the amount of time the fuel lasts in the car. Different manufacturers create fuels that focus on different things.
Look for a blend of nitromethane, methanol and oil. This mixture was specially designed for RC cars rather than other types of RC vehicles like boats or airplanes.
Pick a fuel with 8 to 12 percent gas inside. This will make your RC car perform at top speeds as well as reduce the overall wear and tear on your engine.
Try different fuels until you find one that you like and that fits your needs.
