Castrol Classic Valvemaster with its unique phosphorus formula protects against valve seat recession under all driving conditions. Containing Etha-Guard ethanol stabiliser that protects and enables use of ethanol E5 and E10 petrol in classic cars, motorcycles and pre-1996 petrol vehicles. For use with 95, 97, 98, 99, or higher octane ethanol E5 and E10 petrol.
Valvemaster is the recommended solution for cars and motorcycles requiring valve seat protection. The best protection after lead against valve seat recession Protects your engine under all driving conditions Keeps fuel systems clean Protects against corrosion Valvemaster and Valvemaster Plus provide the best protection against valve seat recession after lead, while keeping the fuel system clean and providing excellent corrosion protection.
Both Valvemaster and Valvemaster Plus contain Etha-Guard, an ethanol stabiliser to protect the fuel system against the corrosive effects of ethanol contained in fuel. Etha-Guard is effective in both E5 and E10 petrol, preventing acidity and corrosion, thereby protecting your vehicle fuel system. The unique phosphorus based formulations provide the best possible protection in all driving conditions - including high speed motorway driving or towing, guarding against metal contact between valves and the soft valve seats - the job previously done by lead. Without such protection, engines may experience valve burning, loss of compression and engine failure.
Classic sports cars engines in particular operate at higher revs, are often driven at sustained speed, and therefore require the level of protection that Valvemaster and Valvemaster Plus provide - something many other lead replacement products cannot offer.
Both products carry the endorsement of the Federation of British Historic Vehicle Clubs and have undergone independent screening to provide users with reassurance. "Independent research shows phosphorous offers the best engine protection, and Valvemaster & trade; ensures consistent performance for engines originally designed to run on leaded fuel."
