With very high batch-to-batch consistency, this fuel is a blend of hydrocarbons & exotic molecules with purity > 98% and is ethanol free.\\

JSK 8 offers a high combustion speed & high combustion energy for use in normally aspirated or turbocharged engines with moderate compression ratios (CR < 14:1).

Do not judge fuel on octane numbers alone. Performance is delivered through combustion speed & energy. Test the fuel by first adjusting your air fuel ratio and then optimizing (often by reducing) spark advance timing. Use the fuel on track to feel the powerful reacceleration and the power increase vs other fuels with higher octane!

ETS Racing Fuels will last at least 12 months in an unopened container.
