No, the info isn't there for all. Just a single blabber teach me all the tech/science in a few sentences post from a new member.
Why does every new thread require teeth pulling?
Let me share my Mazda from the owners manual. If I asked for help picking a fluid, some info that I would provide for each specific component if I was fluid confused.
Manual transmission: Any GL4 or GL5 80w90 or 75w90 gear oil.
Rear differential GL5-only: SAE90 or 80w below some arbitrary temps(don't remember) but prior to SAE 85's and 110's in updated often SAE J306 grade listing. There were no locally available single grade SAE90 or SAE80w oils.... The stock diff, with LS, gets the typical locally available 75w90LS for many years. When the power was increased, I used a 75w140 for the rear diff.
90 grades are plenty thick for the MT and thicker would cause more shift effort. So, the MT continues either 75w90NS or MT90, and have some Ford GL4 75w90 for the next change. In a colder climate, I would consider a 75w85 thumbing my nose at the owners manual's obsolete recommendations. Times change.
Or my Toyota:
rear diff 75w85 GL5
transfer case 75w90 GL5
I used 75w140 in the Toyota since the xfer tends to develop leaks and the diff(older design) took more grades a few years earlier and before the SAE grade reassignment. I went for southern climate thick oil tow protection, especially since it occasionally towed 1.5-2.5 tons as needed, and wasn't looking for the best MPG gear oil. Thumbing nose at Toyota's recommendations!
I don't need to know why/what Mazda/Toyota were thinking, or what is going on concerning ISO/AGMA/SAE ratings, the automaker considerations, or what the additive suppliers have been doing with their formulas and science, and don't even care. Pick an appropriate gear oil, specific to the gearbox, its strengths/weaknesses, and expected usages. That answer is NOT available with the information provided by post #1.
Rarely do I see the same gear oil recommended everywhere. I also thought some 'swivels' had special grease, and maybe aftermarket ones took gear oils.
I also don't see the massive selection of EP vs non EP gear oils at Walmart or any major local autopart store chain. But, we don't know where the OP is located, or what he plans on substituting in place of whatever the OE requirement exists.
Pick the sump, just one..... transfer case, manual transmission, swivel, rear differential, or front differential, steering gearbox, whatever....
Post the specific requirements for that specific component directly from the service manual or owners manual, or both since it sometimes varies, and any mods that might stress that component in order to adapt to what is available now, along with any known issues that some experience with that product range.
Pick a brand that you're familiar with or has some reputation.
Pick an equivalent, substitute, or upgrade available to you in your area.
Repeat for each component sump.
Today, we don't care for EP or non-EP, hypoid or non-hypoid... pretty much down to 'grade', GL rating, and LS or synchro compatibility(only if one cares).
I do care for my manual transmission by picking a suitable MT spec gear oil. I care for my open diffs with a non-LS "GL-5" gear oil. I either LS dose the non-LS gear oil, or use a LS specific gear oil, for my limited slips(common spring/clutch chattering nightmares). I avoid LS additives when not needed. I do NOT fear GL-5 gear oils with my manual transmissions. So, MT GL-4 is just a preference. If I had steering gear boxes, cv joints, swivels, slide yokes, spline gears, slip joints, u-joints, bearings, or other sumps, I'd give them equivalent to what is needed, and maybe adapt/upgrade to weather/climate, usage, failures, or current availability.
