80,742 miles here. Just got around to changing the transfer case oil. It still had a clear golden color to it after 6 years, probably due to whenever it gets run it gets at least 25 miles put on so I guess any contaminants get burned off. Minimal sludge on the bottom oil plug. While I had the bottom cover off I swapped the 0w-20 for 0w-30, engine seems happier with it. Everything looks great under there, dry and clean. I'm not a fan of the bottom cover but it seems to be protecting components down there. Looks like I'll have this for the long haul. Gotta admit I'm impressed more than I thought I'd be with this vehicle. Next will be the plugs and a new set of winter tires.
