Klotz HiTRATE Racing Gasoline ConcentrateHi-Trate Racing Gas Concentrate from Klotz delivers race gas performance at more affordable pump gas prices. Hi-Trate Concentrate unlocks tuning and and engine performance capabilities by increasing octane ratings. Additionally, treated fuels will prevent pre-ignition and detonation while adding more octane than standard fuel. One gallon of concentrates treats up to nine gallons of fuel.Jet changes and timing adjustments may be required when using Hi-Trate. Monitor spark plug health and use at your own risk.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
