Petrol/Gas US Oil for B58 Engines

Not yet. Just shy of 8k on the clock and going to do it at 10k with the diffs. Should be pretty simple in terms of process. Going to use Valvoline 75-90 Synthetic all the way around.

Fill the transfer case until it overflows the fill hole?

Yes - that’s the same on the diffs. You want to do it cold as the oil will expand if it’s hot, but honestly - by the time you drain and fill - it won’t be that hot and your fine.

I personally overfill until it wants to keep coming out of the fill hole and plug it.

I wonder if there is a filter for the transfer case’s radiator system. To filter out metal shavings..
