Setup, Compatibility & Care

To use the Briggs & Stratton Fuel Fit, simply measure the correct amount based on the volume of gasoline in your fuel can or tank. It is highly recommended to add the additive to your fuel storage container before filling it at the gas station so the stabilizer mixes thoroughly during the refueling process. For long-term storage, ensure your fuel container is kept in a cool, dry place out of direct sunlight to maximize the effectiveness of the additive. Always store the bottle itself in a secure, upright position, away from heat sources and out of reach of children.
