Supersonic speed, impressive agility, and a high-performance engine are synonymous with racing vehicles.
Unsurprisingly, such automotive beasts are powered by super-strong engines that are unlike their passenger car counterparts. Racing car motors produce extreme heat and pressure, as well as use more fuel due to the differences in power.
Given that, it is not surprising that typical passenger car engine oils do not work for them. Racing engines require the use of high-performance lubricants, specifically designed to support the harshest operating conditions.
