Do small health care
AlfredClare 
11 After replacing the piston ring, it was the third time for health care. This time it was a minor health care. I changed the oil and oil filter. The oil was as always used by Audi for 5w-40.
Since the stubborn problem of carbon deposition was cured, maintenance has not been sloppy. It has been done every 5000 kilometers. This old Q still wants to use it for a few more years.
Check that there is no lack of oil at all during a maintenance period, which means that the piston ring replacement is correct and the engine performance is normal.
It is recommended that friends who use new cars should not be stingy with changing the oil. It will not be wrong to change it frequently. This is a small amount of money. Changing piston rings is really heartbreaking.![]()
