Ethanol Defender

Ethanol Defender

BG Ethanol Fuel System Defender is formulated to inhibit the free radical oxidation mechanism, which causes ethanol-containing gasoline to degrade. Add to the fuel tank each oil change to keep intake manifolds, intake ports, intake valves and combustion chambers clean and free of damaging deposits typically caused by ethanol. BG Ethanol Fuel System Defender is an excellent fuel stabilizer! Catalytic converter and oxygen sensor safe.


Fuel System Drier

Fuel Drier

Ethanol-containing gasoline is highly susceptible to water accumulation which can cause corrosion on fuel system components. BG Ethanol Fuel System Drier forms a stable solution with water and gasoline allowing the water in the tank to pass harmlessly through the fuel system, without affecting the combustion process. Catalytic converter and oxygen sensor safe.


Ethanol Corrosion Preventer

Ethanol Corrosion Preventer

BG Ethanol Corrosion Preventer forms a protective coating on fuel system components to prevent corrosion. It will keep the entire fuel system clean and restore power and fuel efficiency. Used in each tank, it contains special stabilizers that prevent fuel oxidation, gum and varnish formation that are typically caused by ethanol. Catalytic converter and oxygen sensor safe.
