Hi-Gear INJECTOR & FUEL SYSTEM CLEANER with SMT2 for gasoline engines. It comprises an SMT2 synthetic metal conditioner of the second generation which reduces friction and wear of the parts of the engine cylinder-and-piston group. The metering tank with gradation of the treated fuel in liters helps quickly measure the necessary amount of the additive. It is recommended to be used each 1500 km or more often in case of poor-quality gasoline use.
