INTRODUCING RACE GAS ULTRA RACE GAS ULTRA is specifically designed for the requirements of very high compression, boosted or nitrous engines. ULTRA, when mixed with pump gasoline, will create racing fuel with octane between 108 and 112 r+m/2. Like our original product, ULTRA increases the octane, chemical oxygen and chemical energy of the fuel to equal commercially distilled racing fuel. RACE GAS ULTRA is a much different formula than original RACE GAS. “In testing we found the requirements of very high compression engines were different than engines with lower compression or lower boost. We needed to create a formula that could achieve the high octane while still meeting our requirements of high chemical energy and high chemical oxygen in a consistent and predictable way.
