Millers High Octane Booster - Millers Oils CVL Extra Competition Valve Lubricant - 500ml

Millers Oils CVL Extra is supplied in a 500ml bottle and is formulated as a competition valve lubricant and combustion enhancer for petrol engines. It is intended for high-stress motorsport and track day use, where it protects against valve seat recession and provides flame front control to support more advanced ignition timing without pre-ignition or detonation.

This formulation mixes with leaded, unleaded and lead replacement petrol, as well as fuels containing octane enhancing additives including oxygenates such as ethanol and MTBE.
