They're New! They Block Rust and Corrosion above and below fuel, oil and coolant levels.

They work: Bull Frog additives are a must for vehicles and tools that are stored for more than one month. Bull Frog additives contain high-performance VpCIs that stop rust and corrosion above and below fluid levels. Bull Frog's metal-seeking VpCIs migrate throughout fuel, oil and coolant systems to form an invisible "Molecular Umbrella" of electrochemical inhibitors that seal all internal metal surfaces (above and below fluid levels) from the air and moisture that cause rust and corrosion. Protection lasts until coolant system is flushed, oil is changed or fuel is used up.
