ERC-RUL Racing Gasoline is a completely unleaded, medium density (specific gravity), high heat release gasoline specifically designed to give excellent performance in normally aspirated race engines. No organo-metallic additives are used.

Very high F-1 and F-2 octane numbers and an R + M ÷ 2 octane of 104 allows this fuel to tolerate the lean mixtures and maximum spark lead needed to optimize output in normally aspirated race engines.

ERC-RUL Racing Gasoline has a designed-in low Reid Vapor Pressure (RVP) in order to maximize fuel metering consistency and minimize fuel system vapor/liquid ratios.

In certified A-B-A testing, no other unleaded gasoline (including some with higher claimed octanes) octane-rated higher than ERC-RUL Racing Gasoline.

Also available is ERC-RULH, a slightly heavier (higher Sp. Gr.) fuel which bridges the gap between RUL and the ultra-heavy RUL/T. These fuels have similar octane numbers, with other properties which meet the requirements of certain, specific racing applications. Contact ERC for details.

RUL, RUL/H, and RUL/T are the most highly developed and thoroughly tested gasolines we've ever produced.
