Cleans fuel injectors (excellent results in the Cummins L10 tests). Prevents oxidation of fuel, stopping sludge deposits & filter plugging. Raides the cetane number in diesel fuel to maximize fuel ecomony, reduce emissions & improve cold-weather starts. Special fuel-poor depressants promote fuel flow in cold weather conditions. Isolates & prevents wax crystals from forming. Helps prevent ice formation in system components.Contains lubricants to protect pump & injector parts from wear & scuffing due to low-sulfur fuels.
