Red Line Synthetic Oils & Additives

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.
