OWS 360 Gasoline and Diesel Fuel Treatment Modern cars running on engine control units (ECU) and fuel injections are tuned for high performance but often only driven at less than half the engine's potential due to the start and stop nature of city driving. This type of city driving increases carbon buildup at the intake valves and injectors. Dirty injectors provide poor spray patterns causing poor combustion, loss of power and high fuel consumption. The OWS 360 Gasoline and Diesel Treatment cleans the injectors and intake valves to restore them to peak efficiency, giving better fuel economy and improved throttle response. Dirty Injector Clean Injector   Our flagship product, the Vitamins For Your Car ® series, was developed at great expense and as such, we are proud to say that few can equal the outstanding performance and value that this product line offers.
