High-Temperature Stability Conversely, the high-temperature rating ensures the oil does not break down or become too thin when the engine is under heavy load. By reaching vital moving parts almost immediately, it minimizes wear and tear, providing a protective layer before the engine reaches its optimal operating temperature.
This cold-temperature fluidity is crucial because the majority of engine wear occurs during startup. This stability prevents premature oxidation and the formation of harmful deposits.
