I purchased some MotylGear 75w90 for my front and rear diffs (12 g37x sedan).
This has some different properties than Motul Gear 300 and I was wondering if it still ok to use? Anyone have experience with it? A lot of the viscosities appear similar.

It's hard for me to identify whether I have LSD differentials on my G37X AWD Sedan. I would like to purchase Mobil 1 Synthetic Gear Lube LS 75W-90 for both front and rear differentials. Is this product OK to use in my car in the event I don't have LSD?
I thought I would try again to get my answer before I put Mobil 1 Synthetic Gear Lube LS 75W-90 into my front and rear differentials. Is this oil safe to use in my G37x?

Is there anyone here knowledgeable of the G37x? Is this thread still active?
Thank you for the link. Now I have the information I needed. BTW, with 55K, my rear diff fluid showed particles and nasty film as I poured it out of the drain pan. The magnetic had a good load of gunk on it. So, I believe this change is well over due.
Has anyone used 75w140 in cooler climates? I lived in the PNW and I rarely drive the car since it’s a weekend car. I ordered the wrong viscosity and hoping it would work without returning it but if you guys think it’s going to cause some issue then I will switch it out.
