Hi everyone,
I have a 2013 Volvo S60 T5 with slight oil burning - around 1qt/3k. Seems like the issue is badly designed low tension piston rings with small grooves, where carbon can plug up the drain holes. I want to clean them out without pulling the pistons and changing the rings.
Sure, a flush could work - I'm considering that. But I think its safer to use high quality cleaning oils with short OCIs to slowly remove the gunk.
So, I have two questions:
1. Could high-detergent oils over short OCIs clean up carbon buildup on piston rings?
2. Any suggestions of oils with high-detergent compositions for this sort of situation?
