Post Your Latest Transfer Case Lubricant Change

[UNC151]

I did not see an existing topic, but if this is a duplicate post, please delete it.

2010 F-150 FX4
2nd OC (1st OC was at 13,300)
67,000 miles on oil; 80,300 miles on truck

Out.....Motorcraft Mercon V
In.......Motorcraft Transfer Case Fluid XL-12

I am not sure why Ford used Mercon V when they changed it at 13,300, the OM clearly states XL-12 is to be used. At any rate, that is what is in there now and UOA to follow soon.
