The latest generation of our U4-based fuels, U4.4 Reg makes more power than pump gas across a wider range of applications than its predecessors. Designed as a direct, pour-in replacement for pump gas, it will require modest jetting changes, i.e., +2 main jets or +2 pilot jets at most. With its higher octane rating, U4.4 Reg is designed for use in stock and modified 2-stroke and 4-stroke applications. Contains MTBE.
