Red Line 20W-50 Synthetic Oil

  • For wider bearing clearances and racing engines that see occasional street use
  • 25% more viscosity than petroleum 20W-50s.
  • Not recommended for use in cold climates (15C/5F for 20W50)
  • Recommended for API SM/SL/SJ/SH/SG/CF and ACEA A3

Benefits of Red Line Motor Oil:

  • Fully-synthetic ester formula for passenger cars, light trucks, performance vehicles and marine applications
  • Excellent wear protection and friction reduction across a wide range of operating conditions
  • High detergency allows extended drain intervals and provides increased cleanliness
  • Improved fuel economy and ring seal for more power
  • 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
  • Less evaporation than other synthetics for improved efficiency and ring seal
  • All products are completely compatible with other conventional and synthetic motor oils
