Use regular unleaded gasoline with a posted octane rating of 87 or higher. For best performance or trailer towing, you could choose to use middle grade 89 octane unleaded gasoline. If the octane raiting is less than 87, you might notice when you drive, commonly referred to as spark knock. If you are using gasoline rated at 87 octane or higher and you hear heavy knocking, the engine needs service.
