GEN 2 Diffs and T-Case oil change

[FordPerf Addict]

Hey guys,

Manual says 150K on both of these oil changes. With some offroad and occasional driving thru water off-roading, when are you guys changing them?

Likely to change everything to Redline Products but don’t want to change too early if I don’t have to.

I didn't realize that was the recommended service interval. I did all 3 of them at 120k. Mostly highway miles on my truck.

I changed mine out really early just cause i’m an Amsoil fan. The factory fluid definitely had a lot of life left. Wasted time and money lol? Probably so, but i enjoyed working on the truck . 2018 model with 25k miles.
