What brand/viscosity oil do you use?

 

Bummer. Do aftermarket turbos have this problem as well? Would it be worth it in the long run to change it out?

 

I also went into limp mode one time on my last trip with the camper. Long uphill, 29 PSI boost for a while. Did the same thing, did not let turbo go 20PSI any more. It was suggested that I cleaned the Turbo. I have a scangauge and did not see any codes, may be scangauge does not show it.
