R 6SR is a leaded racing fuel designed for performance engine applications that need leaded high quality and high octane fuel. It is specifically designed for engines needing lead to lubricate the valves and valve seats. Also provides protection against detonation up to compression ratios as high as 13:1 in engines with cast iron heads and blocks. The compression ratios can be higher in all aluminium or iron blocks with aluminium heads. No special set up is required, but for best results tuning is advised. Available in 25 and 200 litre drums.
