Product Description

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.


  • Etha-Guard ethanol stabiliser: Enables use of E5 & E10 petrol with or without a catalytic convertor. Prevents corrosion in fuel systems. Prevents acidity in ethanol fuel. Keeps fuel system clean. Protects your vehicle in use or storage; also prevents damage to fibreglass fuel tanks.
  • Octimise Plus friction modifier: Enhanced performance and economy. Increases acceleration by up to 3% and increases economy by up to 2%.
