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+ contains additional cetane improvers which boost the fuel 5-9 cetane numbers and additional lubricants which reduce wear in low sulfur fuel by 75%. 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% additional power and efficiency. This diesel fuel additive complies with the federal low sulfur content requirements for use in diesel motor vehicles and nonroad 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.
