The Red Line 40WT Synthetic Racing Oil has a global reputation as the ultimate racing lubricant--many teams who have found that the improved performance and equipment durability is the key to winning. Made with the most thermally stable synthetic base stocks available and provide the best high-temperature lubrication and a higher film strength than any petroleum or synthetic on the market today. Although the Red Line 40WT Synthetic Racing Oil is categorized as a “straight grade”, its low-temperature properties make it an exceptional multigrade, allowing 2-4% more power than an oil of similar viscosity, while providing much more protection. Each reduction in viscosity grade allows 1-2% more power. To reduce the chance of detonation, the Red Line 40WT Synthetic Racing Oil contains very few detergents.
