3rd Gen Taco calls for 75w85 gear oil, front & rear. Should I throw the 75w90 I have in it, or order the "correct" fluid? New to Toyotas.

Thanks!

Thread '2016 Toyota Sequoia 75W-90 vs 75w-85'

So I just picked up a 2016 Toyota Sequoia 4x4 with 197K miles (previous owner apparently drove a lot)

we will be doing occasional heavy towing, I move a lot for work and tow a large enclosed trailer. the rest of the time its a grocery getter and kid hauler and the wife's primary vehicle.

Given the miles I want to baseline all the fluids to fresh synthetic,

issue is the diffs and transfer case

front and rear diffs call for a total of 3.81 qts of 75w-85 GL-5
the transfer case call for 1.43qt of 75w-90 GL-5

I am annoyed by the slightly different viscosity, part of me just wants to...

Thread '75w85 VS 75w90'

Hey Everyone,

Our 2019 Santa Fe specs 75w-85 in the transfer case and rear diff.
In the past I have used 75w-90.

I was wondering if you all think the 90 weight would be better for longevity VS .005 mileage increase for the 85.

Thanks

Thread 'alternative to 75w85 gl5 in toyota tacoma'

my Tacoma truck requires using a 75w85 gl5 type gear oil in the differentials, since im limited to using either the Toyota brand gear oil or the redline lightweight 75w85s, what other gear oil would be the best close alternative to those.

Thread 'Gear oil 80W-90 versus 75W-90'

see a lot of people asking if their specification 80W-90 can be substituted with something else. Invariably the chorus here says "use 75W-90 is better because muah, synthetic".
Since my car differential and transfer case also requires 80W-90, I kind of thought... why Toyota din't say 75W-90 if that was so great?
To start, I measured my differential temperature after running 30 minutes in 70 F ambient. Result: 110...117F. For people in the rest of the world that's 43...47C.
I am curious... let's take a look at the viscosities of various gear fluids at this temperature. Not at frozen -50C...

Hey Guys,

Sorry...but another Super Tech question. Toyota calls for 75w85 or a GL5 equivalent. 75w85 is not east to find at all! Any issues with going with Super Tech 75w90 Syn gear lube in the front and rear of the 4Runner?

Has anyone used this...is it a pretty decent fill? Looks to have the legit specs....

So we have 2019 santa fe AWD, oem.is 75w-85 usually our other cars have used a 90 weight.
My question is......did they chose an 85 weight for meg's or longevity?

We want to keep this car a LONG time.

Would you swap it out for a 90?

Thread 'Any Difference Between 75w-90 and 75w-85?'

My 4WD truck calls for 85 in the front axle and rear diff, and then for -90 in the transfer case. Would it be safe to just get a case of the 90 and use it everywhere? Seems absurd to be buying all those single bottles for 5 points of viscosity. Thanks.

Thread 'Toyota Tundra 75W85 Gear Oil....'

My 2011 Toyota Tundra calls for 75W85 gear oil for the rear differential. This weight is pretty hard to come by...can I use a good full synthetic 75W90? If so, is Mobil 1 a good choice?

I plan on changing the rear gear oil early because I want to squeeze as many mpg's as possible out of my truck given these high gas prices. I have heard a good quality full syntheic gear oil may help some, as well as offer really good protection long term.

Any feedback would be greatly appreciated. Thanks...

Hello Everybody,

We just bought a used a Hyundai i10 (PA) 2012 1.2 liter Petrol car with ~132K Km on it and a manual transmission.

We want to maintain it before use and so we are contemplating an oil change (especially since these cars are generally used in urban conditions and by young people as a first car, so the trans must have been a little abused if we had to guess). Also, please note that this car will be used by the wife for 95% city driving, daily from home to work/gym/groceries( we have another car for longer travels).

Well I just found out that my '09 toyota comes stock with 75w-85 in the front and rear diffs. Toyota even issued a TSB for older yotas to start using the stuff. Does anyone have a PDS on this stuff?

Hello all,

I am in the early stages of considering purchase of a 2011 Toyota Tacoma V6 4WD. As part of the research into this possible purchase, I downloaded a copy of the owner's manual and read through it. I was surprised to see that Toyota specifies 75W-85 for the Differential. I thought this was interesting. I know Red Line makes a 75W-85, but I am not aware of any other offerings in this weight range. I believe Toyota is still recommending 75W-90 for the transfer case and front differential. Will 75W-85 become an increasingly common viscosity range? Do other vehicles out there...

Thanks! I should have searched for more that "Tacoma Diff" smh
 
You can safely substitute 75w-90 without any concern whatsoever. Gear oil viscosity ratings describe ranges of viscosity. A 75w-85 on the thick end of the range might be practically identical to many 75w-90 oils. Nothing to worry about.
 
If you already have 75w90 on hand, I would use it. But if using OEM grade makes you sleep better, use it. Either grade will work perfect in your Taco.

Never fails 🤣
 
I sell parts and fluid to a local toyota dealership. I literally sell them bulk valvoline 75w90 because there is a TSB/recall on all tacomas from 2012 up to 2023 models (last time i asked) to use 75w90 in both the front and rear diff. Apparently they sneakily change it over when the vehicle is in for another service as they were having to warranty differentials on a regular basis. they have been buying a couple hundred quarts from me every 2 weeks for at least the past year and a half.
 
I did a used oil analysis on my 21 that I posted in the used oil analysis section. I am planning to run a few different viscosities to see how they wear. So far i've only done the used oil analysis on 90wt and that wasn't very favourable. Currently running a 85wt since that was my plan before receiving the results from the 90wt... so far i'd recommend Tacoma owners run atleast a 110wt and I haven't even officially done a used oil analysis on it yet

I have never heard of that TSB. Why still spec 75w85? hmm
 
90W is great. Choose your favorite. Mobil, amsoil, valvoline - I like amsoil or amsoil SVG if I’m towing heavy.

I'm not sure, I wouldn't know about it had i not been contacted by the local dealership. Also, My guess is money? Toyota probably got a large deal on 75w85 at some point as well as it inflates the fuel economy by just enough to make Cafe happy in the US. Fuel economy only matters for tax purposes as it is sold off the lot. Not what it gets after the first oil change.
