I changed my axle fluid at 2000 miles and it had the normal shiny streaks of metal. Used synthetic 80-90. Changed again around 12,000 miles and it looked black. I will now change it @ every oil change.
They don't hold much, might as well go with synthetic 80-90. No cooling fins on the chunk. Mine runs a little hot, but I run interstate about 2/3 of the time.
Don't forget to grease the inside too including splines.
