Klotz HiTRATE Racing Gasoline Concentrate The Klotz Hi-Trate Racing Gas Concentrate is a solution designed for achieving race gas performance at a lower cost. By elevating the octane ratings, the product enhances engine performance and offers improved tuning possibilities.More than regular fuel, this concentrate provides greater octane, safeguarding against pre-ignition and detonation. It offers substantial coverage, with a single gallon enough to treat up to nine gallons of fuel. Further adjustments such as jet changes and timing modifications might be necessary when using Hi-Trate. Given the potential for spark plug health implications, users should proceed with caution. Specifications: Mix 1 gallon of HiTRATE Race Gasoline Concentrate to 9 gallons of 92 octane unleaded pump gas (or greater): Yields an octane rating of 103 to 105 depending upon the purity of the pump gas Provides excellent results with compression ratios of 11:1 to 12:1 100 octane aviation gas may be used to produce octane levels of up to 110 Jet changes are sometimes necessary when changing octane or gasoline Gasoline varies in its specific gravities which will alter fuel velocity and performance Note : Take several plug readings, then adjust timing and jets accordingly. Features: Pump gas power additive Converts standard pump gasoline to higher octane racing gas 1 gallon concentrate to 9 gallons of 92 octane pump gas yields an octane rating of 103 to 105 Recommended for 2- and 4-stroke applications Race fuel technology at pump gas prices Allows higher compression ratios and advanced timing to create more horsepower Prevents damaging detonation and pre-ignition Smoother engine torque curves Adds lubricity to dry unleaded gas For use with unleaded, oxygenated (Mtbe) pump gasolines Catalytic converter safe Not for sale or use in the state of California
