What is the appropriate oil level when the engine is cold?
1 Answers
The oil level when the engine is cold should be above 3/4 between the upper and lower marks. Below is extended knowledge about engine oil: Classification: Mineral oil, semi-synthetic oil, and full synthetic oil. The classification is mainly based on differences in base oils. Generally, mineral oil uses Group II and Group III base oils, semi-synthetic oil uses Group III and Group IV base oils, and full synthetic oil uses Group IV and Group V base oils. Lubrication performance: Mineral oil performs the worst, full synthetic oil performs the best, and semi-synthetic oil falls between the two. Oil change intervals: Mineral oil typically requires changing every 5,000 kilometers, semi-synthetic oil every 7,500 kilometers, and full synthetic oil every 10,000 kilometers. If the vehicle has been parked for more than three months, it is recommended to change the oil before use.
