Description Leaded ethanol-free storage fuel for engines needing leaded fuel. As with the CFS Storage Plus, CFS Storage 5-Star is completely free of ethanol and made from pure hydrocarbons and petroleum chemicals. It is, as the name indicates, leaded to help preserve valves, valve seats and cylinder heads in engines not designed for unleaded petrol. Its very high octane level of 103 RON and 98 MON protects even extremely high compression engines from detonation. It is storage safe for at least three years and vehicles will start on the button even years after they have been laid off. 10 Litre
