FEATURES AND BENEFITS Adds up to 4 octane numbers to base fuel. Enables older competition engines to run on unleaded fuel*. Proven chemistry protects against valve seat recession. Provides similar flame front control as lead, thereby enabling engines to run more advanced ignition timing without danger of pre-ignition or detonation. Mixes with leaded, unleaded, lead replacement petrol, and other fuels containing octane enhancing additives including oxygenates such as ethanol and MTBE. Equally effective in modern engines fitted with knock sensors and catalytic convertors. Protects against the corrosive effects of ethanol found in modern E5 and E10 unleaded petrol.
