Diesel Purge is one of the best products you can use to keep your diesel injectors and pump clean . Running a can of Diesel Purge through your engine (via the fuel filter hoses, it does not go in the tank) will result in a noticeably quieter and smoother engine.
Due to its flammable nature, Diesel Purge can only be shipped by ground service and cannot be exported.
