Using the recommended 91 octane gasoline is your best choice. Using lower octane can cause fouling, miss-fire and detonation(pinging). While not too detrimental in the short term, this can cause premature engine wear over time. If you really need to save money at the pump, Try mixing regular or mid grade with premium in various ratios until you find a blend that runs well. Or Don\'t buy a car that requires premium.
