Red Line 15W50 Engine Oil (1 Quart) - 11504

Recommended for API SN/SM/SL/SJ/SH/SG/CF and ACEA A3/B3/B4

This oil is particularly popular in turbocharged applications and has been specifically formulated for engines that have wider bearing clearances such as racing engines that see occasional street use. This oil also has 25% more viscosity than petroleum 20W50. We do not recommend this oil for use in cold climates (-20C/-4°F for 15W50).

About Red Line engine oils:

  • 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
