Millers Oils CVL is a competition valve seat lubricant and combustion enhancer which has been expertly formulated to protect against valve seat recession.

It can be used as a lead substitute to prevent valve seat recession, or also by engine builders to compensate for deterioration in pump fuel. Use of this product will also protect vehicles that are susceptible to the destructive effects of ethanol.

Dosage Rate:

• 1 x 250ml bottle will treat 20 litres of unleaded fuel

• Proven chemistry to protect against valve seat recession
• Enables older competition engines to run on modern, unleaded fuel*
• Equally effective in modern engines fitted with knock sensors and catalytic convertors
• Provides similar flame front control as lead, enabling engines to run more advanced ignition timing without danger of pre-ignition or detonation
• Mixes with leaded, unleaded, LRP and other fuels containing octane enhancing additives (such as oxygenates, ethanol and MTBE)
• Protects against the corrosive effects of ethanol found in modern E5 and E10 unleaded petrol

* Please refer to motorsport governing body for fuel treatment regulations
