Since 1979, Red Line Synthetic Oil Corporation has grown to manufacture more than 100 quality products, including motor oils, gear oils, assembly lubes, fuel additives, and its popular WaterWetter cooling additive for the automotive, motorcycle, marine, and industrial markets. Based in Benicia, California, Red Line has a reputation with racers and enthusiasts alike for creating products that perform and protect better than any on the market, regardless of price.
Red Line formulates fully-synthetic oils and chemically-advanced additives using the world's finest base stocks. Rather than cutting costs by blending in petroleum products, Red Line's motor oils and gear oils use superior ester base stocks that provide extreme stability at high temperatures and superior film strength at lower viscosities where more power can be produced.
