Amsoil Products ATF, MTF, Gear Oils

Thanks, that gets me back on track now. Helpful to know Toyota isn't tapping some underground spigot reserved for elites only

 

I say another factor decides.

If you live in a warm/hot place the

$28 75W-90 Synthetic Gear Lube - 1 Quart (Pack of 2)

75W-90 MTG will be great, cool/cold place I would go with MTF.

 

Well ..... I mean.....













We have some things here that the Cheby bois could only dream of having .....

 

When you say cold.... Do you mean like "winter is coming" or do you mean like "Hoth"?

 

Not even that cold.

Say a couple or six freezes in the winter. Snow one or 3 times kinda cold.

 

I've tried both syncromesh and gear lube for the manual tranny. If you drive unloaded or in my opinion below freezing most of the time then i'd say go syncromesh.

-40* the gear lube is clunky for sure but I also find that it warms up within a couple kms. I also find that when it's "cold" but 20*c for the first couple shifts it's clunky but obviously diminishes after the first 2 shifts.

syncromesh is a nicer shifting oil but if you're planning to do truck things then stick with the gear oil. When I tow, haul or just drive on the highway for a long time, you can feel that the gear oil is at the perfect viscosity. Where as the syncromesh feels perfect around town but after long drives and/or loaded it gets notchy and almost wants to grind into each gear

 

So like.... STL cold

Good info. Gear oil for me then

 

So what gear oil is recommended for the 3rd gen? Same

$28 75w-90 Synthetic Gear Lube - 1 Quart (Pack of 2)

75w-90/75w-110 for front/rear instead of the specced 75w-85?

 

Same

 

I was perusing the magazine the other day and saw the various greases Amsoil sells. I don't have any serviceable components but, is there any reason to not use the off road grease in automotive chassis components (aside from wheel bearings and u-joints) other than it being overkill?

 

It’s fine it really stays put

 

What oil for transfer case 3rd gen automatic?

 

See first post under TC

MTF

Thanks!

 

went with the lazy packs. Not the most cost effective but hopefully it’ll save some time.

 

Question: what's the difference between the Fuel Efficient ATF and the Multi-Vehicle ATF? They're both listed for import and domestic. Just curious.

AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid | ATL - AMSOIL

AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid | ATF - AMSOIL

 

The difference is viscosity. The ATL being newer, lighter. For EPA MPG. 2013 should have AW spec. ATL.

 

Curious what is your take on fuel additives such as this? I have a handful that were free with a bulk purchase, but I'm not sure I'd pay for it separately.

Not who you asked, but...
I use both UCL and PI on regular basis (UCL since 2021, PI since 1980).
Follow intervals on the bottles.


Fuel additives are one thing, but NEVER add anything to your oil.

 

So should i be using fuel additives regularly? Is there a certain point when additives should be started? My truck has 32k miles but my wife's rav4 has around 70k miles, should i use it in her car regularly?

 

My 4Runner and Tundra both say 75W for TC (not 75W90). Is that 5W30 manual trans fluid linked on page 1 really comparable to a 75W?
