CFS Storage 5-Star is ethanol-free, made from pure hydrocarbons and petroleum chemicals. It’s leaded to protect valves, valve seats, and cylinder heads in older engines. Its very high octane level of 103 RON and 98 MON protects even extremely high compression engines from detonation. Safe for storage up to three years, ensuring easy starts even after long periods of inactivity.
