It is a fundamental problem of combustion engines: exhaust emissions and fuel residues dirty the fuel and intake system. Performance levels drop, fuel consumption rises and the exhaust gas values become worse. With the JetClean Tronic II by German additive specialist Liqui Moly garages can give the engine and fuel system a thorough cleaning. “The engine breathe freely again and the garage attains additional sales with the service,” says David Kaiser, research and development manager at Liqui Moly.
