Which is it, are they identical or are there differences? [emoji38]

I don't think such a thing exists. They make one 75w90 and it clearly says it contains additive.I used the Royal Purple gear oil with no additive.
As long as it doesn't say "LS" on the bottle then sure, you can't go wrong. There is this which shouldn't be used...Cannot go wrong with the GM/A C Delco gear oil, if it was not good, the factory would not use it.
If I'm understanding, this is fine in a ZR2?I don't think such a thing exists. They make one 75w90 and it clearly says it contains additive.
However, you have a ZR2 so you don't have a G80 and your lockers don't care if there's an additive in the gear oil.

"Formulated with a friction modifier additive, therefore no additional additives are necessary."

Yeah, the electronic lockers in the ZR2 don't care one bit if there's additive or not since there are no clutches involved at all. You can use gear oil with or without additive and you'll never know the difference.If I'm understanding, this is fine in a ZR2?

Good. Because I had already purchased it and then saw this thread. Hoping to get it done this weekend.Yeah, the electronic lockers in the ZR2 don't care one bit if there's additive or not since there are no clutches involved at all.

Mobil has different products . This is the correct one . Shop around for the best priceThanks, I thought I read here somewhere that a guy used Mobil 1 with negative results?
Either will be fine it....
The one thing that is said is not to use Limited Slip Additive.
I have used with Limited Slip Additive in mine.. and have had no issues.
But either Delco GM synthetic 75-90 or Mobil 1 and you will be good
I can see how someone could easily become confused about this, since the Eaton MLocker (G80) uses friction discs to lock both axles together.It doesn’t really matter. Most modern synthetic gear oils have barely any additive.
Just don’t add any more.
That's nice. You're not doing your G80 locker any favors if that gear oil has friction modifier, though.I use Amsoil on all my cars and trucks. Great results for the past 30 years. Minimal wear on all wear parts.
