Our take on the Sierra eGuard Ethanol Fuel Treatment

Sierra eGuard is a fuel additive for E10 gasoline engines. It stabilizes fuel for up to 12 months, removes water without alcohol, and cleans the fuel system to prevent gum and varnish. It works in both 2-cycle and 4-cycle engines, so one bottle covers mowers, trimmers, generators and stored equipment. Rivals like Sta-Bil and Sea Foam also stabilize fuel, but eGuard's non-alcohol water remover aimed at phase separation is its main differentiator.
