A The rule of thumb is to use the lowest-octane gasoline that will operate the engine efficiently. For the vast majority of modern cars and trucks, that means regular unleaded, which is typically 87 octane. The octane rating of gasoline is a measure of the fuel's resistance to ignition, meaning the higher the octane rating, more heat and pressure are required to "start the fire." If the recommended octane gasoline provides proper starting, power, drivability and efficiency, there's no benefit to using higher-octane fuel.
