Classic Valvemaster™ and Valvemaster™ Plus
the best protection after lead
Tested and endorsed by fbhvc
Tested and endorsed by the Federation of British Historic Vehicle Clubs. The unique phosphorous based formulation provides the best possible protection against damaging metal to metal contact between the valves and the soft valve seats - the job previously done by lead. Without such protection your engine may experience valve burning, loss of compression and engine failure.
Lead Replacement Petrol Additive
