Race cars on track

Sunoco DXP was developed to exceed the needs of engines that push bore size, high compression ratios and extreme rpm levels. Sunoco DXP delivers extra protection against detonation during the best atmospheric conditions for improved performance within a demanding feature race or endurance events. This precision blends allows for greater durability and reduced wear in today’s top level race engines.

Sunoco DXP is for off-road and racing use only.  It contains additives to enhance stability and minimize oxidative effects.  As with any gasoline, DXP should be stored in opaque, tightly sealed containers where temperatures are stable.  Handled under such conditions, the shelf life of Sunoco DXP is 3 years or more.


Legal in California only for racing vehicles in sanctioned racing events.


For off-road and racing applications only.
