HiTest is a concentrated, metal-free octane booster designed to increase power by increasing octane number and combustion efficiency. The advanced formulation eliminates knocking by increasing the auto-ignition temperature of the air/fuel mixture and readily mixes with all fuels, including nitro and alcohol mixtures. The all-organic blend contains no metal or phosphorus compounds and effectively increases power at dosages as low as 1 oz. HI-TEST per gallon of fuel.
