Is there a difference between P/S fluid and ATF?

[nthach]

Toyota systems aren't picky about fluid. FWIW, I've used Mobil 1 ATF in my parent's Sienna and despite the fact these and the Canadian-built Lexus RX have a tendency to spring a leak from the passenger's side rack bushing seal, the rack innards were clean. LV "universal" ATFs have become my power steering fluid of choice for systems that use ATF.

If it was a car calling for a specific fluid(German cars calling for Pentosin/Mercedes ZH-M fluid, GM/Chrysler calling for power steering fluid and any electrohydraulic system calling for OEM-specific fluid), stick to that. I know Molakule has said here the plain Jane power steering fluid for "domestics" is a zinc-phosphorous containing fluid and there's barely any zinc in a typical ATF. Red Line, however is selling their ATF as a power steering fluid for GM/Mopar applications.

And they now have a PSF:

Only their D4 states you can use it in PS systems but that is ONLY when the Manf. states that you can substitute a Dexron III/Mercon ATF for PSF.

See above.

I recall saying that Redline PSF could be used in a Manual Transmission requiring an ATF-like fluid because of it's additive package.

Upon your recommendation, i am getting good results in my 96 f150 m5od using the Redline psf...

What do you think of redlines new lowest viscosity mtf? Do you think it would substitute for the psf?

Would be nice if Redline shed some light on the additive pack . . . . . . .

Another example... Amsoil makes a generic Power Steering Fluid that is for use in all vehicles that don't specify another type of fluid, but certain vehicles they will call for their Multi-Vehicle ATF instead as per their application guide.

My Santa Fe originally used the generic Power Steering fluid without issue because that is what Amsoil listed and the manual was vague, but in my Journey and now my Caravan call for ATF so that is what I used in the Journey and what I will use in the Caravan when the time comes to change it. The original spec for Dodge is ATF+4 or Mopar Power Steering fluid if you can find it. (My local dealer doesn't have it)

The Amsoil application guide lists the OE's specification in the notes section below the products of theirs they recommend for the application including various information like Mopar MS-9602 material specification number for example so I like using it to find out what the actual spec is if the manual is vague or doesn't list it.

I mean on the MTF

Or is it the same?

 

[justintendo]

It very well could be..it seems to have slightly different specs though..

mt-lv

API Service Class GL-4
SAE Viscosity Grade (Gear Oil) 70W/75W
Vis @ 100°C, cSt 6.5
Vis @ 40°C, cSt 29.8
Viscosity Index 175
Pour Point, °C -60
Pour Point, °F -76
Brookfield Viscosity @ -40°C, Poise 60

psf
Typical Properties
Rust (D66A/B) Pass
Vis @ 100°C after shear 6.47 cSt
Foam 0
Fire Point °C 258
Copper Corrosion 1b
Vis @ -40°C 18,000 cP
Vis @ 100°C 6.47 cSt
Vis @ 40°C 34.7 cSt
Viscosity Index 143
Pour Point, °C -50
Pour Point, °F -58

i think ill try it out next service...

Basically it has the same addpack but a slightly different viscosity base oil mix.

I have suggested for years that for Redline to make an MT-LV all they need to do to take the PSF addpack and use some lower viscosity synthetics.

Now it's Amsoil's turn to catch up.

My 2013 Tacoma calls for ATF Dexron 2 or 3.

I did and flush and drain on mine this past weekend using Valvoline Maxlife ATF.

My landcruiser specs the same

I did the same with Total ATX D II...
