Ford OEM oils?

This may sound dumb, and I ask because after 47 years of driving and servicing 200+ trucks Ive never seen diff lubes or T case lubes like what come out of my 99's diff and T case. I wont even mention the trans as I know better Ive had way to many beater old trucks and have never seen black lubes like what I found in my F250. Is the factory stuff loaded with Molly, or has my latest machine been rode hard and put away wet as they say. It looks like what's on Joshepny's hands from his F550.

T-case would be ATF but it'll be black if old. Also not uncommon for old timers to put gear oil in these chain driven cases, which honestly isn't a real big deal. Lubrication is lubrication

That's what I was thinking. May be gear oil.
