Wondering if Amsoil SVG gear oil for my Toyota Tacoma (non slip locking diff) is any better than the off-the-shelf Mobil 1 Syn Gear Lube. Both are GL-5. I want to change front/rear diffs, and the transfer case, all calling for GL-5.

I guess using the LS gear oil in a non-LS diff is ok?

You will undoubtedly receive many opinions on this, but arguably Amsoil gear oil is one of the best (if not the best) on the market and I have used it with great results. I am not affiliated with Amsoil in any way--just my experience. With that said, M1 is also great oil. You may want to consider moving your viscosity up 1 level for the rear axle to 75W-110 as it was the upper viscosity that 75W-90 used to be before the SAE J306 tables were updated a while back.

PS...no issues using LS oil in a non-LS axle (only the reverse is an issue with potential clutch pack chattering).

I would think the Mobil 1 is equivalent to the Amsoil Long Life gear lube and the Amsoil SVG is a step up from the Mobil 1.

I use SVG as the cost is pretty low (when you consider quantity and frequency) and I can be confident that I have one of the best gear oils in the differential. I sleep well.

Been using the Mobil 1 gear oil in my Ram in signature for the last 60,xxx miles. Great gear oil at a great price. Amsoil is really great also -- just never tried it personally in a vehicle. Did run it in my 08 Road King 103c.i. with good results.

I have used Mobil Delvac 1 in three G80 lockers now and the front diffs too … $100 gets free shipping so that’s three gallons or two plus grab something else.

I use Chevron Delo in my truck no issues at all. If blended by a reputable blender I can't foresee any issues.


make the inside of your engine oil cap white.
don't use.

I would say Amsoil Severe Gear is the best of the best. THIS is where Amsoil truly shines!!

Probably ok with either. I've used Mobil 1 Syn Gear Lube 75W-90 for 30 years without issue. Never did a post gear inspection or UOA, though.

Unless severely misapplied, gearboxes are pretty tough and often will die of contamination (dirt, water past seals or ingested in breather tube) 1st before any oil breakdown. In fact, CAT moved their bulldozer drivelines up in the 1980's for just this reason - too many geardrives were dying from dirt contamination past the seals, so they moved the geartrain up.

Agree Amsoil Severe Gear PAO is top in the market. I'd probably only use for a severe application - racing, overload, hot climate, etc. Otherwise M1 should be good enough. LS in non-clutch differential is ok. The other way around is not ok. Just changed my Chev Kodiak C5500 rear end @ 50,000 miles with M1. 2-1/2 gallons!

I’d call that total failure with Pennzoil !!!

UOA? Never heard of this happening.
