3. Check the fuel level Raise the rear body and check the fuel level. Refill the tank to the upper level mark if necessary. Your engine is designed to use any gasoline that has a pump octane number (R ; M ) of 86 or higher, or that has a research oc- tane number of 91 or higher. Gasoline pumps at service station normally display the pump octane number. We recommend that you use unleaded fuel because it produces fewer engine and spark plug deposits and extends the life of exhaust system
