Classic Etha-Guard Plus
Stabilises E5 & E10 ethanol petrol. Fully compatible with catalytic converters, Etha-Guard Plus offers the best protection against ethanol damage for drivers of younger and modern classics.
Etha-Guard is an additive that counteracts ethanol’s hygroscopic nature, preventing moisture and subsequent acidity in your fuel system. Etha-Guard protects both in use and in storage, stabilising the fuel to prevent moisture absorption and separation.
All products in the Valvemaster Fuel Additive range contain Etha-Guard. Classic Etha-Guard Plus is compatible with catalytic converters, so can be used by owners of younger and modern classics who do not require valve seat protection.
