ATF: Amsoil Signature vs Toyota WS vs Idemitsu

[lexus300]

The Amsoil fuel efficient blue bottle says it's compatible with WS.

I just did a fluid drain and fill with amsoil at 60k for my lexus and the shifting is so smooth. So happy with amsoil.

I cringe every time someone calls Amsoil "snake oil". That's simply not true as they have very good products. You can disagree with how the products are marketed or the price, but calling the quality "snake oil" is just trolling and nothing else.

Yep Amsoil works great in WS applications.

Is this the part were you just invent some issues people have had with Amsoil ATF?

Oh, I don't think so.

 

[Nesterenko]

Which Yota? A lot of the car variants have an actual filter

It's in his post. Sequoia

Has anyone tried HPL ATF Green CC?

Has anyone tried HPL ATF Green CC?

I have 4 gals of it, but haven’t found anyone who would allow me to use it. All of my customers are opting for OE when I present them with the options.

You haven't tried it in your own Camry? Or Prius' power split device?

I suppose I could, but I also have a large inventory of WS.

How else are you going to convince customers to use the HPL stuff, if you haven't even used it in your own vehicles?

Our GS is due. I'll be over later... HPL for the win!

my next atf change will probably be idemitsu... amsoil makes good stuff, but some transmissions are finicky and don't like generic fluid (curse you jatco) so it's idemitsu or Mitsubishi fluid, other fluid says it meets Mitsubishi spec but it says that about every other spec, and some people have problems with generic fluid. iirc aisin transmissions will work with any fluid, the question is how long it'll last with different fluid. send it with amsoil or idemitsu and don't worry about it

I've been using Amsoil ATF on/off 20 years in my Mitsu requiring SP3. Highly recommend. Idemitsu is great too.

Although; OEM is always safe bet.

 

[dumkid]

what mitsu do you have? some transmissions are more fluid tolerant than others, and some universal fluids work while some don't. i haven't found much data on which fluids cause shuddering in the monteros, everyone just says to use factory fluid from the dealership

 

[Krieg]

Montero 6G74. V4AW3 tranny. Only used Diaqueen SP3 or Amsoil. Currently Amsoil.

 

[dumkid]

ok, it's an aisin transmission. i have the jatco v5a51, which has more fluid related problems. thanks for the data though.

Does the Idemitsu fluid have any licenses?
