Perhaps not. But oil change is coming up in a few months so any fancy oil might be worth a try.
Currently using Mannol 7701 5w30
Could a thicker oil perhaps help with piston slap?
Yep another valvoline restore post..
Has anyone found this oil in eu? Paying 40 euro to ship it from usa is not viable :P
Ive got a citroen c1 @220k km that has more piston slap than I would like.
Any tips or oil recommendations
