It seems like Mobil 1 75w90 is good all 'round in a toyota taco

[ChrisW]

I've searched, and it seems that mobil 1 75w90 is good all 'round in the toyotas. This includes the front and rear diffs, and the transfer case as well as the manual gear box. But at $9 a quart at kragen/autozone, I think I may go with amsoil or redline.

My buddy's taco is hard to shift, really notchy; i dont believe the fluid has ever been changed. I was thinking of redline MT-90 in the gearbox and 75w90 in the rear diff. Either that or Amsoil MTG and then their 75w90 in the rear.

His is a 2WD, not 4WD so no worrying aobut xfer case and the front diff.

Maybe something conventional would be better? But may as well go synthetic.

$9/qt is a good deal for M1 75w-90 at Kragen. Even at wholesale, Amsoil would cost more.

Not true. Supposedly, many Toyotas also have a "final drive" unit that requires service as well. Check the manual to be sure, but most "final drive" units for cars with a MT take the 75w-90 as well.

I think you can get Amsoil for about 7.70 per quart at preffered custom prices..

Not too bad..?

Delo esi gear lube will equal or out perform M1 for way way less. I have used mt and mt90 Redline in my 92 4X4 6 cyl toyo and both work real good .Redline gear lube$ work well ,But are not needed in a Toyota.

And what you gonna do?.., you only need about 3qt for transmission and even less in rear deff. Most good synthetics 75w90 cost around nine dollars +- $1 anyways.
M1 gear oil performs extremely well in toyota truck including smoother shift and mpg increase. Heard some good results with redline (don’t even think to find cheaper then M1) Other options – you may buy cheapest dino ST or something like that for about $6 a 5qt jug.

I can buy redline 75w-90 gear lube any day of the week for $10 canadian at my local tuner shop.

That means our American friends should be able to pick it up for $7.50 - $8.00USD.

Yes, myoilshop.com used to be a sponsor here and they sell Red Line Oil for something like $8.00 per quart. I think it's less than that but with shipping it's close to $8.

Since the quantities are small and oil change intervals usually very long, I don't let the cost of a gear oil disuade me ... unless I think I'm getting screwed.

I have 3-4 bottles of Amsoil MTF synchromesh 5w30 laying around, so i'll use that in the transmission, and then imma buy some Mobil 1 75w90 for the rear diff.

I don't think the Amsoil MTF is too thin for this app; i'm sure it will be better than whats in there.

 

[bmwtechguy]

The 5w30 synchromesh would be too thin for Toyota manual gearbox, especially if a 75W-90 GL5 is recommended in the owners manual as some I've serviced. I would think that Molakule's GL4/GL5 MTL would be a great oil in this app, or one of Amsoil's 75W-90 GL5 or their GL4 Manual Transmission Gear Lube. I've used Redline MT-90 with good success in the past as well in manual gearboxes.

 

[ChrisW]

Note taken. I went ahead and went the next town over and bought 3 qts of Amsoil 'MTG' 75w90 at about $6.99 ea. I am hesitant to use the thinner MTF in the toyota transmission.

(I'll use the Amsoil MTF in my civic which is currently running Redline MTL.)

Will report back later with results.

For the transmission fluid, make sure you get GL-4.

 

[ChrisW]

Amsoil 'MTG' is GL-4, toyota calls for a 75w90 GL-4.

People are using Mobil 1 75w90 in transmissions, which is MT-1 and GL-5 rated.

 

[par]

My 2001 tacoma can use gl-4 or gl-5 in the transmission.

 

[OdinsRage]

i dunno if the MT-1 rating is good enough to be used in a GL-4 spec'ed box, any thoughts?

 

[Grossomotto]

M1 75W90 Gear Fluid will work fine in that Toyota Trans, many many people are doing it.

But, I think SF MTL-P 75W85 is perfect for the Toyota 5Speed Trans.
