Red Line 50WT Race Oil is a 15W52 competition grade for engines built with wider bearing clearances, and a long-standing choice for methanol applications. Packaged in the five-gallon pail.

Key Features

  • Used in applications with wider bearing clearances
  • Popular with sprint and midget applications on methanol, offering less frequent oil changes due to less fuel dilution
  • Polyol ester base stocks provide more stability and film strength under heavy fuel dilution
  • No less than 2200 ppm of zinc and phosphorus for antiwear protection
  • Special detergents for improved lubricity and reduced detonation
  • Higher film strength than any petroleum or synthetic Red Line lists on the market
  • Categorized as a straight grade, but low-temperature behavior makes it an exceptional multigrade
  • Red Line lists 2 to 4 percent more power than an oil of similar viscosity, with a further 1 to 2 percent per reduction in viscosity grade

Applications

Engines with wider bearing clearances. Red Line lists it as popular in sprint and midget applications on methanol, where less fuel dilution allows less frequent oil changes.
