I have some Amsoil synthetic severe gear 75W90 sitting in my garage, would that be alright to put in my shitty 10bolts for a oil change, i have the GM limited slip additive also. Just wanted to ask, because i dont know if putting the synthetic in will be too smooth for the rear, granted i would be adding the limited slip.......... so anyone out there with some comments please let me know, and the reasoning why

I understand the synthetics and the posi additives dont mix together leaving the posi clutches starving for the needed additives. can't prove it, I just read it, might be a bunch of BS too.

If you rear end can run synthetic I do add bottle addictive anyway, even the gear oil say it already have addictive in it.

and if you rear end run just regular dino gear oil, I do still add bottle of addictive to it too.

if i was trying to help a 10 bolt survive I would throw the heaviest, most shock absorbing dino oil in it... not a 75w90 synthetic

....and this is a Fact, I agree. Just sucks trying to get gear oil here its like pulling teeth or crazy expensive, this is what i have in the garage. The 10 bolt will be no more once i get back to the states hopefully a fab 9

Per Amsoil the Severe Gear 75W90 has the LS additive already in it so you do not need an additive.

AMSOIL SEVERE GEAR® is compatible with most limited slip differentials. If limited slip differential chatter occurs, add AMSOIL Slip-Lock™ friction modifier additive.

This is the oil that I am going to run in my 9" ford. Here is a comparison chart of all the gears oils. They test all the oils and Amsoil comes out with the best grade. All the proof I need.
