Technical Information:

HappyFuel premium fuel stabilizer offers improvements in oxidation stability over conventional fuel stabilizers. With ethanol blended fuels and conventional gasoline, addressing humidity in your fuel becomes critical. HappyFuel’s premium chemistry addresses oxidation, lubrication, vapor pressure suppression, and water scavenging, thereby addressing the issues of fuel storage from all mechanistic ends. It does this by:

1. Bonding with gasoline compounds to prevent evaporation of low-end components
2. Forming a protective layer along the engine metal that prevents condensed water from corroding the metal
3. Prevent corroded metal ions from destabilizing gasoline compounds into resin, which can hinder fuel injection components
4. Scavenge water to prevent water deposits at the bottom of the tank, limiting biological activity.
