Great gear oil have noticed a 3 mpg increase in my wife’s Jeep Wrangler with nothing else being changed. I did both front and rear differentials. Also it doesn’t smell awful like most gear oil which is nice.
Yes, I would recommend this to a friend.

Severe Gear Oil
September 19, 2020
I’ve always used Severe Gear Oil in all of my differentials and I’ve never had an issue; after 50k, it still looks clear and viscous. The squeeze bottles make the drain and fill process even easier. Spend the extra money for the piece of mind and go Amsoil.
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....
