A valve seat lubricant and combustion enhancer that protects against valve seat recession. CVL also provides flame front control allowing engines to run more advanced ignition timing, without danger of pre-ignition or detonation. Enables older engines to run on modern unleaded fuel, and is equally effective in modern engines fitted with knock sensors and catalytic converters.

One bottle (250ml) to treat 20 litres (maximum) unleaded petrol for all motorsport applications. Precise treatment levels should be determined by test bed experimentation
