50WT Race Oil
- Designed for applications with wider bearing clearances.
- Ideal for sprint and midget applications on methanol, allowing for less frequent oil changes due to reduced fuel dilution.
Further Information
- Reformulated to enhance frictional properties.
- Contains special detergents for improved lubricity and reduced detonation.
- Polyol ester base stocks ensure greater stability and film strength under excess fuel dilution.
- Each product contains a minimum of 2200ppm of zinc and phosphorus for antiwear protection.
- Multi-grade formulation provides 2-4% more power compared to oils of similar viscosity: 20WT is a 5W20, 30WT is a 10W30, 40WT is a 15W40, and 50WT is a 15W50.
- Offers improved protection at startup, lower oil temperatures, and enhanced cleanliness.
- Change these oils more frequently than standard engine oils.
