Under the premise of the same viscosity of engine oil, if the flash point of engine oil is higher, it means that the evaporation of engine oil is smaller, so that even if the engine oil is at a higher temperature, it can be ensured that it is not easy to catch fire. If it is too low, it is likely to cause hidden dangers of accidents, so you still need to pay attention.

Precautions:
1, when adding lubricating oil, don't increase it frequently, otherwise the effect of lubricating oil will be greatly reduced. Be sure to use lubricating oil correctly.
2. After adding lubricating oil, it is not recommended to continue adding other additives, because a variety of additives have been added to a good lubricating oil. If other additives are added at will, the effect will be counterproductive, resulting in a decline in the effect of lubricating oil.
3. The blackening of engine oil is indeed the performance of oil deterioration, but not all engine oil blackening is caused by the change of oil. Some automobile lubricating oils are added with a quiet decomposer, which mainly means that the black carbon deposits adsorbed on the engine piston are washed down and decomposed in the lubricating oil, so the oil looks black.
