The Castrol Valvemaster provides the ultimate protection against damaging metal contact between the valves and the soft valve seats – the job currently done by the lead in the petrol. Without such protection, your engine will suffer valve-burning, loss of compression and engine failure!
Castrol Valvemaster also keeps the fuel system clean and provides excellent corrosion protection in all driving conditions.
Castrol Valvemaster Plus provides an octane boost to unleaded fuel, reducing pinking, knocking or the need to retune.
