Based in Benicia, California, Red Line Synthetic Oil has been pioneering high performance fluids since 1979. From the popular Red Line MTL and MT90, to D4 ATF and 75w90 gear oil, Red Line is the go-to for fully-synthetic oils and chemically-advanced additives like WaterWetter. Red Line fluids are designed to handle higher temperatures associated with hard street driving and the tortures of track use, while remaining extremely stable.
