With all the good talk about HPL, I am looking at using their 75w-90 gear lube in the differentials of my `18 4Runner, `16 Suburban and `97 Dodge Ram. All 4WD, so 6 axles in total. Anyone have any experience with the gear oil they would like to share that makes it above and beyond the Amsoil Severe Gear, Scaeffers, Redline, Ravenol, Valvoline, Mobil 1, etc.?
I see it already contains the friction modifier for the limited slip that is in my `97 Ram rear. I don't think it is needed in the other axles, but I guess won't hurt.
Not really worried about price, as it is only like an every 10year/100,000 mile change.
Or should I get the 75w-85 for the 4Runner and the rear dif or the `16 Suburban or not worry and the 75w-90 will be good for all?
I will also do the transfer cases as well... 75w for the 4Runner, Dex6 for the Suburban and ATF+4 for the Ram.
Like always. I will be doing the work myself.
