Size:1 Gallon (128 Ounces) Red Line's 85 Plus Diesel Fuel Additive Treatment is designed for use in all diesel engines and contains extremely powerful lubricants, detergents, seal conditioners, fuel stabilizers and rust preventatives, but without smoke suppressant. Red Line 85 Plus contains additional cetane improvers which boost the fuel 5-9 cetane numbers and additional lubricants which reduce wear in low sulfur fuel by 75 percent. This improvement in lubricity and cetane will reduce detonation, assist starting, help reduce smoking, help prevent fuel system wear and leakage and can provide 5 percent additional power and efficiency. This diesel fuel additive complies with the federal low sulfur content requirements for use in diesel motor vehicles and non-road engines. 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 degree Fahrenheit.
