Can full synthetic engine oil last for one year?

[ValeriaLynn]

The recommended replacement interval for full synthetic engine oil is approximately one year or 10,000 kilometers. Relevant information is as follows: 1. Long lifespan: Currently, common full synthetic oils on the market are made from Group III base oils through hydrogenation. Full synthetic oil is superior to conventional mineral oil and semi-synthetic oil, offering better stability, oxidation resistance, and corrosion resistance, which naturally results in a longer service life. Generally, it should be replaced once a year or after driving about 10,000 kilometers. Therefore, if your car uses full synthetic oil, using it for a year is generally not a problem. 2. Superior performance: Due to the superior performance of full synthetic oil, it is suitable for high-end vehicles or those requiring higher performance. For economical family cars with regular oil maintenance, semi-synthetic oil may be more appropriate. Full synthetic oil is not suitable for all vehicles. Older vehicles with long service times are recommended to use semi-synthetic oil because these older cars have relatively poorer sealing. Full synthetic oil, with its low viscosity and good fluidity, may be more prone to leakage, making higher viscosity semi-synthetic oil a more suitable choice.
