We formulate VP Small Engine Fuel (SEF) from higher-grade base stocks that make for a superior clean-burning fuel. Our ethanol-free 40:1 mix, 50:1 mix, Multi-Mix, and 4-Cycle small engine fuels eliminate damage caused by ethanol-blended pump gas in outdoor power equipment. All VP Small Engine Fuel is blended with only the best components with no unnecessary filler additives. Plus, our SEF’s remain stable in the tank for up to two years and up to five years in an unopened container. You don’t need to add fuel stabilizers.
