Since most GL-5 gear oils for differentials are too slippery for manual transmissions, Red Line offers these products that ensure proper shifting while providing ultimate wear protection
Since 1979, Red Line Synthetic Oil 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.
Founded by president Tim Kerrigan (retired) and the late Peter Filice to produce lubricants for the racing industry, Red Line Oil now distributes its diverse line of products across the globe. The company brings a knowledge of available technologies and responds to technical challenges, satisfying the high demands of the performance industry. Red Line's employees are enthusiasts that stay on top of each racing and performance niche, ensuring that product recommendations allow customers make the significant performance gains.
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.
