SS 100

SS 100® is an unleaded high octane gasoline that is street-legal in California and a few other locations that follow CARB regulations. Its 100 octane rating will allow increased boost levels in supercharged or turbocharged applications compared to premium pump gas. Sunoco SS 100 can be used in high performance vehicles both old and new. It can also be used in applications such as motorcycles, ATVs, karts, and other smaller engine vehicles.

Sunoco SS 100 will not harm catalytic converters or oxygen sensors. It does not contain metallic compounds. SS 100 contains a comprehensive additive package to minimize engine and fuel system deposits. It is compatible with two-stroke synthetic and mineral-based engine oils. As with any gasoline, it should be stored in opaque, tightly sealed containers and kept where temperatures are stable. Properly stored, the shelf life of SS 100 is in excess of 1 year.

If you are looking for a 100 octane unleaded fuel outside of the California area, ask for 260 GT.


Street legal in California only.
