OK, we know highway miles on an oil better than the stop-and-go and idling. I believe this is generally based on the performance of a NA engine. But what about turbos? For those who do not have the glowing-hot chunk of oil-ruiner attached to your vehicle, highway speeds (65+ mi/hr) necessitate the use of higher and prolonged boost levels (especially on hills). So, on a Turbocharged engine, which is "better?" Highway? Stop & go? Idle? I realize that it is possible that these three situations may stress and consume different components of the attitive package and oil. Thoughts?
