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 stock one fluid,

we are in Florida and I would think I could get away with 75w-90 in all 3 compartments with probably some small imperceptible decrease in fuel efficiency being the worst effect, but I am open to ideas


I am looking at red-line, I have used it in the past long term with good results, their 75w-90 is 16 cst at 100c and the 75w-85 is 12 cst at 100c, 40c is 112cst vs 68cst

thoughts? stock two diffrent fluids? run all 90wt? run all 85wt

I have always gone with 75w90 over the 75w85 in my previous cars/trucks differentials, that called for it. Zero issues...150,000 of driving, no problems whatsoever.

I have used Redline, Mobil 1 and Valvoline. Didn’t notice any sort of difference between any of them.

I think you’re fine using 75W90 in all three. Your truck is a lot like mine underneath. I used 75W90 AMSOIL in the front and rear differentials. No worries.

Consider yourself lucky that your transfer case takes 75w90.

Many Toyotas (including my own 4Runner) use a straight 75w in the transfer case, which raises a whole lot of questions in itself.

If it was mine, 75w90 in all without hesitation.

I actually just earlier today read about that straight 75wt that costs $50-100 per qt that is used in some years, apparently if equipped with a borg warner transfer case. but at least for 2016 both the owners manual that came with the truck and the one online call for 75w-90 GL-5

They are almost identical from the firewall forward, I see you are running 5w-30, I have been running M1 10w-30 in all my Toyota's for years, all older, newest until now being a 99 LS400, I am currently looking for a Toyota recommended engine oil weight for temperature chart for the 5.7 3UR-FE from outside the US, I feel the 0w-20 is for CAFE reasons only, have you found any such date?

for earlier years there was a caveat for high temperature or heaver loads heavier oils could be used (same motor) but my 2016 has no such carve out for the same engine. I would love to see what Toyota says when not HAM strung by CAFE regulations.

If you must run 75w85, Redline has it.

I've been running Mobli One 75W-90 in my Sequoia's front, center, rear diff for many years and miles. No problems. You will love the Sequoia. It is built like a tank.


... using Mobil 1 since 1976.

^^^ Same here. M1 75w-90 in all three and never look back.... 157,000 miles and counting and never paid much attention to the Toyota's meandering viscosity requirements.

As others have said 75w-90 would be fine but in your case of heavy towing I would use 75w-140 in the rear. I'm using the SuperTech syn version of 75w-140 in my 4Runner with no problems or hits on MPG.

ka9mnx is on to something. Only I would go to 75w-110 in the diffs and 75w-90 in the Transfer case.

You said heavy towing...

And I wouldn't stock any fluid. I'd get just what I needed and be done for 50K. If you are using RL or Amsoil SG
you will be fine.

I run 75w-110 in all my vehicles. It is what used to be the thicker end of the old 75w-90 viscosity range.

I wound up going with all 75w-90, Thank you all for the replies, i figured it would be OK but wanted to check in with the hive mind first. I hate finding out things the hard way.

I was originally thinking Redline as I have had redline in my LS 400 for about a decade but with just a single sump to fill the cost is a lot easier to swallow. for this gallon and a half purchace the price was more of a sting, found a decent price on Mobil Delvac 1 at about $10/qt after shipping, for a synthetic that gets good reviews here, just ordered 2 gallons,

still all over the place on engine oil, I was up to speed on this stuff 15 years ago, a lot has changed.


Re 110/140, I will be doing occational heavy towing but it will be occasional, once a year kind of thing, not sure if I want to go that far from spec, although given the climate it probably would not cause harm. The majority of its use will be kid hauling (3 here and a fourth on the way)
