Can I bring my own engine oil to 4S for maintenance?

Bringing engine oil to 4S for maintenance is not allowed in most 4S shops, because if there is a problem, it is not clear whether it is the responsibility of engine oil or the responsibility of 4S shops.

The first insurance free items generally include oil change and three filters, and generally you can enjoy free maintenance for half a year or every tens of thousands of kilometers.
