Description
Description
VP Racing Motorsports MS 100 is a professional-grade, unleaded 100-octane race fuel developed for motorsports applications. It is the spec fuel for IMSA sports car racing in North America, providing teams with a consistent, purpose-built fuel option for competition.
MS 100 has a 94.5 MON, 106 RON, and 100.3 (R+M)/2 octane rating. Its 3.61% oxygen content supports performance potential in properly calibrated engines, while its controlled properties give racers a dependable baseline for tuning, testing, and competition.
Because MS 100 is oxygenated, engine calibration may need to be adjusted when switching from pump gas or a non-oxygenated race fuel. It is an unleaded formulation, but racers should still confirm compatibility with their specific engine, fuel system, sensors, emissions equipment, and series rules.
MS 100 is orange and available in 5-gallon pails and 54-gallon drums. It is intended for competition and off-road use where permitted.
