we have to be on different pages. who said i 'judged' oil differently for a turbo than other internals? although a turbo is more 'fragile'(if you will). so not maintenancing oil properly, the turbo may well be first, most likely effected. and yes a higher quality oil definitely should perform better. (when use properly do not put a high quality oil in an engine case for the first time at high-mileage <very important point).
cooking or scalding oil is a fairly immature way of operating a/your vehicle. most stock set-ups this will not happen. perhaps in an extreme, like a very long,steep hill at very high speeds, and be like you get to the top and shut motor off. -for aftermarket, the more turbo work, yes it can come into play, &/or with quite a bit more engine power,performance. then again if you built it, or had a good shop build it, you must know it/when oil gets that hot. or your shop made you aware of what that type of situation is.
where in my above post did i make a differentiation between oil in a turbo and an engine?
why would you even imply a high(er) quality oil doesnt make a difference, isnt that 'kind-of' the idea?
one of the things i outlined was changing oil at proper intervals, a good point, if oil is old, or perhaps,&, has impurities, like soot, and such, flowing, wouldnt you mark the turbo to most likely to be the first, and perhaps most effected. kind of obvious, at least to me. idk.
