1. Racing Car Engine Oil & Ordinary Engine Oil
(1) Racing Car Engine Oil Features
As racing car engines focus on high performance and high power, their engine oil requirements are getting more and more rigorous, including as a minimum:
① Excellent lubrication performance at high temperatures
② Good wear-resistance/anti-seize performance
③ Superb thermal/oxidative stability
Viscosity/temperature properties are also critical in racing car engine oil. In other words, racing car engine oil must keep the engine components appropriately lubricated when the engine rotates at high RPM and under high load (thus the oil temperature rises to a higher level).
(2) Racing Car Engine Oil vs. Ordinary Engine Oil
Racing car engine oil is designed to focus on anti-seize performance at high RPM and under high load; particularly under excessive load it features excellent thermal stability.
However, as it is not particularly resistant to oxidation, with a relatively short service life and. In particular, inferior sludge dispersion performance at low temperatures, it deteriorates faster than ordinary engine oil if it is used in ordinary vehicles (racing car engine oil is designed to be replaced for each race).
To sum up, it is recommended that racing engine oil be used in racing cars for which speed matters, and ordinary engine oil be applied to ordinary vehicles as the latter is designed to cover a wide range of applications considering various operating modes
(high-speed driving, stop & go, etc.), weather conditions (summer, winter, etc.), fuel efficiency improvement, catalyst poisoning, etc.
