V70 T5 sludge problem
So, everyone (including me) thinks the use of mineral oil at 7.5K mile intervals caused problems in this turbo-charged Volvo engine. This is probably true, but just for the sake of argument, what other factors could have been responsible or contributed to this? I think we've seen a few UOAs of mineral oil in turbo applications and while they didn't look great, they didn't look terrible either. Of course, we haven't seen a history of 50K+ miles on such oil...
Any thoughts? You can see mine in the link above.
I'm just glad it's not my car...
