Rant: Blew a turbo on a 6.7 Powerstroke outside of Phoenix last week and now I'm second-guessing my go-to oil change interval

I had a 2015 F-450 I've been maintaining for a local ranch since 60k miles. Ran perfect until 185k when the turbo seized up on the I-10 near Casa Grande. I've always done full synthetic changes every 7,500 miles like clockwork, but my buddy swears he runs his farm trucks to 10k with no issue and says 7.5k is just wasting money. Anyone here ever had a turbo failure that early on a 6.7 and think it was oil-related?

185k is actually decent for a 6.7 turbo, 7.5k intervals are fine.

185k out of a 6.7 turbo, and you did 7.5k oil intervals the whole time? Man, that's wild. Most guys I know with those trucks are swapping turbos by 120k at the latest, even with religious maintenance. You must have gotten the one built on a Wednesday or something, no joke. Mine started smoking at 98k on the nose, and I was doing 5k intervals with synthetic. You're sitting on a unicorn.

My uncle had a 6.7 that started eating oil around 130k, but he was running 10k intervals with conventional. He drove that thing for another 60k miles with a quart low between changes and it still pulled a gooseneck trailer twice a week. Finally sold it with 190k and the new owner put another 30k on it before the turbo went.
