Millers Oils CVL Extra – Competition Valve Lubricant & Octane Booster

Millers CVL Extra is a high-performance valve seat lubricant and octane booster, specially formulated for motorsport, track days, and classic performance engines. Designed to protect against valve seat recession while increasing octane by up to 4 numbers, it provides precise flame control for advanced ignition timing—without the risk of pre-ignition or detonation.

Ideal for high-stress engines running on unleaded fuel, CVL Extra helps bridge the gap left by the removal of lead from petrol, while also countering the corrosive effects of ethanol found in E5 and E10 fuels.

Key Benefits:

• Boosts fuel octane by up to +4 RON

• Enables older and classic engines to safely run on unleaded petrol

• Protects against valve seat wear in high-performance engines

• Mimics the flame front control of lead, allowing more advanced timing

• Effective with leaded, unleaded, LRP, and modern fuels with ethanol or oxygenates like MTBE

• Safe for engines with knock sensors and catalytic converters

• Used by leading engine builders to offset declining pump fuel quality

Mixing Ratio:
1 x 500ml bottle treats up to 20 litres of unleaded petrol. For optimal results, testing under controlled conditions is recommended.

Pro Tip:
Use with premium high-octane fuel for best performance gains.
