Red Line MTL may be used in transmissions which recommend 75W, 80W, or 85W GL-4 gear oils, or SAE 30 or 5W/10W30 motor oils. If a 90W GL-4 or SAE 40, 10W40, or 15W40 is required, MT-90 may be used. If the transmission or transaxle requires an SAE 90 GL-5 gear oil, then Red Line 75W90NS or 75W140NS Gear Oil may be used.

SI-1's injector and valve detergent is a concentrated package of the most powerful high-temperature detergents available to clean gasoline fuel injectors, intake valves and combustion chambers. Redline SI-1 Complete Fuel System Cleaner can clean injectors to nearly 100% efficiency in one treatment. The cleansing effect on injector deposits can raise fuel economy approximately 12% or even greater, depending on the condition of the injectors. Although many gasolines advertise injector cleanliness, GM presented a paper to the SAE which indicates that their customers encountered injector plugging with all major brands of gasoline (SAE 861533). SI-1 also contains detergents and a synthetic upper cylinder lubricant which will help clean the intake valves, pollution control valves, combustion chamber deposits and carburetors. One bottle of SI-1 to a tank of fuel can reduce octane requirements by two numbers. SI-1 also protects the fuel system from rust. One bottle treats up to 100 gallons. Safe for continual use. 15 oz. bottle.
