Frequently Asked Questions

If your car requires premium and you accidentally fill with regular, modern engines have knock sensors that retard timing to prevent damage. You may notice reduced performance and slightly worse fuel economy. Fill with premium on your next fill-up. This is a minor issue if it happens occasionally.
Follow your owner's manual recommendation regardless of whether the car is new. Engine break-in does not require a specific fuel grade. Use what the manufacturer specifies from day one.
Vehicles requiring Premium Gasoline typically include luxury and performance vehicles. Your owner's manual and the label inside your fuel door specify the required grade. Using a lower octane than required can cause engine knock and reduce performance over time.
Only if your vehicle requires or recommends it. For vehicles designed for regular 87 octane, there is no measurable performance benefit from upgrading to Premium Gasoline. If your manual specifies Premium Gasoline, the investment protects your engine.
