RED LINE® Diesel Fuel Additives promote better fuel combustion and fuel system lubrication.

They provide faster ignition, reduce detonation, reduce smoke, and improve engine efficiency. Extremely powerful high-temperature detergents clean fuel injectors. Lubricants significantly lengthen injector and pump life and reduce ring friction which is very important for today's low-sulfur fuel. Both Red Line Diesel Fuel Catalyst and 85 Plus are available as a winterized version which will reduce the pour point of a typical fuel by 25°F.
