A leaded fuel designed with the old '5 Star' in mind to provide excellent protection for historic racing engines. This fuel conforms to the current FIA Appendix J regulation for leaded petrol. It conforms to the British Standard for leaded petrol BS4040. The lead content, combined with the high RON and MON values, not only provide excellent valve seat protection but also reduces knock in high compression engines.

Used by many front running and championship winning racers in the UK. Official fuel of Gentleman Drivers and HSCC.
