Redline Full Synthetic 10W40 Motor Oil

Redline 10W40 is recommended by PREracing for Subaru turbocharged applications for racing use, engines with higher miles, or engines with forged pistons.

Redline Oils feature fully-synthetic ester formula for passenger cars, light  trucks, performance vehicles and marine applications. They provide excellent wear protection and friction reduction across a wide range of operating conditions. High detergency allows extended drain intervals and provides increased cleanliness. Helps improve fuel economy and ring seal for more power with superior high temperature stability and oxidation resistance. Increases lubrication of hot metal compared to other synthetics. High natural viscosity index (VI) provides thicker oil film in bearings and cams with less evaporation than other synthetics for improved efficiency and ring seal. All Redline products are completely compatible with other conventional and synthetic motor oils.
