I have not done the T-Case as yet, but have some Ravenol on deck to do so after I use it a few more times. However, I did change the front and rear axle oil and my advice to everyone is to dump it far sooner than you planned--particularly the rear axle which was loaded with iron after only 5K miles:All are not going to recommend 25K intervals, but from my late model Mopars the oil life monitors seem to indicate 10K for oil lifespan for my driving.
I always change at 4-5K max with decent oil. Oil is cheap, and while some of these synthetics can go longer, I am more concerned about the filtration. Would rather dump the oil more frequently for that reason and keep the engine clean.
I also prefer higher viscosity, not a fan of 20W oil but run whatever you like, it is your engine.
How many are changing the lubes in the diffs and T-case.
