I swore my diesel could hit 500k miles on cheap oil, then my turbo ate itself at 212,000 in Flagstaff

I was towing a trailer up I-17 when the boost gauge flatlined and a mechanic named Walt showed me the coked-up oil feed line, so now I run full synthetic and change it at 7,500. Anyone else get humbled by a repair bill that was totally self-inflicted?
