Recommended for engines that regularly run very high oil temperatures. Best for engines that run large clearances such as air-cooled engines or large-displacement and all-out racing engines that see occasional street use. Provides 25% more viscosity in bearings than a petroleum 20W50. Not recommended for street use in production engines that see sustained oil temperatures below 225°F (those engines should use Red Line 10W30 or 10W40).
