I use it for my diffs in my Wrangler that I take off roading allot, amsoil treats me well!!

It's a gear oil... I just poured it in about a week ago. Can't really say anything yet. I suppose it does what it should. I actually overfilled the rear differential because my truck was on the hill when I changed the oil, so I wanted to make it right and parked on the leveled surface today and unscrewed the fill plug. About 6 oz of oil came out. I noticed its color and translucency changed after a week of driving. It was noticeably darker. About 150 miles. But to me it means that synthetic stuff cleans the dirt and residue that was left there from my old conventional oil. I might need to do another differential change shortly then I expected. But after that second change - I would leave it alone for a loooong time....
