Rear Differential Fluid - SAE 90 vs 80W-90

The manual for the 2002 Tacoma states to use SAE 90 over 32 degree Fahrenheit or 80W-90 below 32 degree Fahrenheit. Can I assume that 80W-90 should suffice in most conditions? I live in Wisconsin and temperatures are generally going to be above freezing but will, like now, be below freezing temps. My local auto parts store has the 80W-90 on hand, whereas I would have to order in SAE 90. Thanks.

 

I'd use the 80w90 or even 75w90 and forget about it.

 

80w-90 will be fine.
My 07 said the same thing.
I used 80w-90, I’ve seen low to mid teens temp wise. No issues yet.

 

due to availability most people run 75W90. 80W90 is also acceptable but harder to find.

When hot 75W90, 80W90, and SAE90 are all the same viscosity so no worries there.

 

Think the last one I got was Lucas 75w shocky stuff.

 

You will be fine with 75w90 synthetic gear oil.

Lately, in this part of IA.....32*F would be a nice 40* increase.

 

80w90 can be found at walmart under the supertech brand.

 

Thanks guys. Got myself some 80W90.

 

80W-90 is an upgraded version of SAE 90 for all intents and purposes

 

I have been using 85W140 in every Toyota I had for the last 25 years.

A 55 gallon Drum lasts a very long time.

 

80W-90 is what I used with no problems in hot conditions as well as freezing cold conditions.

I switched to 85W-140 Lucas oil for the diffs when I re-geared because that is what ECGS recommends for all diffs they re-gear and/or install lockers in.

 

Just in case anyone still cares...there is a company called Ravenol (German company I believe) that makes a "Ravenol Hypoid Gear Oil EPX SAE 90 GL-5" (J1C1135-001-999) and sells it direct from their RavenolAmerica.com website, Blauparts.com authorized dealer website, and on Amazon (**Note that the bottle image on Amazon looks different vs. Ravenol site and product number in description is different**). MSRP is $16.95/L + shipping&tax when purchased direct, or (at the time of writing this) $22.95/L on Amazon.

Also, if larger quantities are needed, ravenol.de/en (English language version of the European website) shows that bulk quantities are available, but I'm not sure if it's affordable or even possible to have these large quantities shipped internationally. RavenolAmerica.com ships domestically, but only has the 1L size available.

Carry on.

 

I use 80w90 Valvoline in all my Tacoma's rear diffs and front diffs use 75w90
