VP Racing MR PRO6 REG Race Fuel

VP Racing MR PRO6 REG is an AMA SX/MX-legal, unleaded race fuel engineered for 4-stroke motocross and supercross competition. It is formulated to help racers pursue maximum horsepower while remaining within AMA Pro Racing fuel requirements.

MR PRO6 REG is designed to make more power than other AMA-legal fuels while minimizing the tuning changes often required when switching race fuels. VP states that it requires only minimal jetting or fuel-mapping adjustments and does not require radical ignition-timing changes.

With 86 MON, 104 RON, and 95 (R+M)/2 octane ratings, MR PRO6 REG is an oxygenated fuel containing 3.89% oxygen. Its controlled formulation gives racers a consistent baseline for engine setup, testing, and competition. Because it is oxygenated, confirm your engine's fuel delivery and calibration with a qualified tuner or engine builder before use.

MR PRO6 REG is colorless, unleaded, and contains MTBE. It is available in a 5-gallon pail and is intended for off-road competition use where permitted.
