Transmission Fluids. Red Line® Engine and Transmission lubricants have long been the choice of racers and knowledgeable engine builders.
The thermal stability, film strength, and reduced parasitic drag found in Red Line® engine oil all contribute to lower operating temperatures, increased engine life, and more power. Red Lines’® racing heritage is reflected in all of their products. You’ll see more Red Line® products at the track than any other lubricant manufacturer for all of these reasons.
