Thinking it's time to change out transfer case oil and saw a recent vid saying to use the Ford XL-12 Transfer Case oil, not the Mercon ATF originally specified. It also mentioned to change every 40k miles rather than the 60K written in the manual.
Just curious if anyone has used anything else with good or bad results. I believe the XL-12 is a full synthetic so I may stick with it.
Cheers
