VP Racing Motorsports MS 109 REG Race Fuel

VP Racing Motorsports MS 109 REG is an unleaded, highly oxygenated race fuel designed for racers who need more power than premium unleaded fuel can provide. VP states that MS 109 REG can produce up to 5% more power than premium unleaded gasoline when the engine is properly calibrated for its oxygenated formula.

MS 109 REG is recommended for boosted applications running up to 25 psi of boost and naturally aspirated engines with compression ratios up to 13:1. Its 9.32% oxygen content supports increased power potential, while its unleaded formulation makes it appropriate for racing applications that require an unleaded fuel.

Because MS 109 REG is oxygenated, fuel delivery and tuning must be adjusted to match the fuel. It is not a direct replacement for pump gas without recalibration. The formula contains MTBE and is not currently available in Colorado, Connecticut, Massachusetts, New Hampshire, or New York due to state regulations.

MS 109 REG is colorless and available in 5-gallon pails and 54-gallon drums. It is intended for off-road and competition use where permitted.
