Gasoline Grade
So which grade of CITGO gasoline is right for you?
Your first reference should be your vehicle Owner’s Manual. Each auto manufacturer provides the recommended minimum octane for normal operation of the vehicle.
- As a general rule of thumb, however, use the octane grade which prevents your engine from knocking or pinging (engine knock is caused by the pre-ignition of fuel as it’s compressed in the cylinder, milliseconds before the normal spark plug firing).
CITGO provides three different octane grades of gasoline – complete with our proprietary high-performance detergent additive. The detergent additive that you will find in all grades of CITGO gasoline is designed to help keep your engine clean and performing well. This additive performance occurs without you having to worry about it. The detergent additives in all grades of CITGO gasoline meet or exceed the Environmental Protection Agency’s (EPA’s) additive requirements.
