Can unopened engine oil be used after it has expired?

The shelf life of unopened engine oil is usually 5 years, but since it has expired, it must not be used. Expired engine oil can not provide normal lubrication and protection for the engine, which will affect its use. Don't hoard engine oil next time, it's useless. I directly changed the long-acting engine oil, GT engine oil, and maintained it once every 12000 km, which would save a lot of trouble. It is not cost-effective to hoard engine oil.
