keep tires inflated toward max tire pressure recommended, clean air filter, clean engine oil, and try using premium fuel may cost more but maintains fuel systems and get more miles per tank and cheaper than adding additives. You can also add friction reducing additives to engine and trans/diff. to reduce friction internally to get more MPH and better performance.
