The best protection for your engine
Classic Valvemaster™, Valvemaster™ Plus, and Etha-Guard™ Plus
Now with Etha-Guard - superior ethanol protection
Valvemaster fuel additives provide you with the best protection against issues caused by modern petrol. Valvemaster and Valvemaster Plus offer tried and tested protection against valve seat recession - the best protection after lead. With the introduction of ethanol blend petrol, Etha-Guard has been added to the formulation to provide additional protection against the effects of ethanol on your fuel system. Etha-Guard is also available as a stand-alone product for owners of younger and modern classics fitted with catalytic converters, who do not require valve seat protection but do require protection against the negative effects of ethanol.
Petrol Additive For vintage and classic
Valvemaster is the recommended solution for vintage cars and motorcycles requiring valve seat protection. Valvemaster Plus is ideal for classic vehicles that will also benefit from enhanced performance and economy. Both products contain Etha-Guard ethanol stabiliser. Etha-Guard Plus is an ethanol stabiliser for younger and modern classics that are designed to run on unleaded petrol.
E10 has been introduced in 95RON
Following the recent Government consultation, a decision was made to introduce E10 petrol in the standard 95-octane grade. The roll-out of ethanol blend E10 happened at the end of 2021, and it is now the standard grade on forecourts. Higher ron petrols are available, but these are now E5 with up to 5% ethanol. As well as the issues ethanol can cause in classics, E10 ethanol is not suitable for all younger classics and moderns.
