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.
