Castrol Full Syn Multi ATF Vs Castrol Import Muti

[David1]

First this is about Honda / Acura

Im sorta confused here.
From what I read you can use Castrol® Transmax™ Full Synthetic Multi-vehicle
in Acura and Honda and it says DW-1... read on..


Castrol has.

Castrol® Transmax™ Full Synthetic Multi-vehicle is a technologically advanced, low viscosity formulation specially designed to deliver maximum fuel efficiency for modern automatic transmissions. It is blended with premium base stocks and is fully approved by both Ford and GM for use in vehicles requiring their latest ATF specifications. Exceeds requirements of JASO-1A and recommended for a wide range of import vehicles.

As you can see is Full Synthetic... & Transmax Multi Import Is NOT.

Seems very similar to what the back of this bottle says, about on HG DW-1 about
low viscosity formulation and Low viscosity formula for maximum fuel efficiency &
smooth transmission performance
Superior high temperature protection to effectively resist oxidation
Not the same but very similar

and it says in data sheet Honda Acura Z1 and DW-1
Honda/Acura
ATF-Z1, ATF DW-1, (except in CVTs)
but in other 2 products its only DW-1 for Honda and only the Full Synthetic is for both
Honda and Acura.. Hmmmm


Perhaps pics from the PDF are better, and my point is I have never seen this product say HONDA ATF Z1 & DW-1, I have only see that in the Transmax Multi Import ATF..

So if you had to use 1, what do you think has the better specs as far was is posted.

Strange both work for Honda DW-1 but might have Different shear cSt and Viscosity and Flash Poin other tech stuff.

read on.
Now here is the Castrol Transmax Multi Import ATF, that says for HONDA , Toyota , Acura on the bottle.

I find this odd.. I would think the Full Synthetic would be a stronger and overall better product... but I do not know about the vst and flash point info.. what is the better test info.

Strange its DW-1 is not listed for Acura. I thought they were the same as Honda.

Here is the test info that some tech savy people might be able to make heads and tails about what would be the better ATF for a Honda.

Now just for the heck of it , the Castrol High Milage Multi ATF...
Looks like they added DW-1 to the list.. however here is the info about the fluid so a tech savy person should be able to say what would be the best choice out of the 3 list products here that all say DW-1 For Honda and only 1 say DW-1 For Acura and that was the Castrol® Transmax™ Full Synthetic Multi-vehicle, has Honda and Acura listed as approved for Z1 and DW-1 and the other 2 products have Honda listed as Z1 and DW-1 but Acura only Z1.. Very ODD...

here is the test info the tech savvy people will be able to make heads and tails from.

I always use Real Honda Z1 and now Honda DW-1 however the price of Honda DW-1 is just killing me.... and Im looking for somthing else.

So from looking at all the info and this is for Honda people... what ATF looks like to be the better Fluid.

The Castrol® Transmax™ Full Synthetic Multi-vehicle
that is listed for DW-1 for both Honda and Acura and is FULL Synthetic

or

Castrol Transmax Multi Import
that is not a Full Synthetic or even a Syn Blend that is Honda DW-1 but not listed for Acura.

or
Castrol High Milage Multi ATF
that is listed Honda DW-1 but not for Acura
and is not a Full Synthetic or Syn Blend.

So what has the better scores when it comes to cSt and Sheer and Flash Point ECT???

I would think the Castrol® Transmax™ Full Synthetic Multi-vehicle

but Im not really a expert and have always use Honda Genuine ATF Z1 or DW-1

Sorry the post is long but I wanted it show all aspects as many Honda and Acura Owners do not want to pay 11$ a QT for ATF.

So what ATF has the better Typical Physical Characteristics Test Method Typical Results

Any Info would be very nice.

Thank you

1 more thing.

I had a post about this ATF before but didnt have as much info, as I do in this post.
Just wanted to make sure if someone looks it up.
Plus I want to know what the people whom are very tech savvy about Physical Characteristics Test Method as in Flash Point ECT... This stuff looks good and if you compare it with the HONDA DW-1 Bottle it says nearly the same thing.

Also its $6.99 at AUTOZONE... Probably less if you have a Code to save $.

$6.99 a QT is not bad at all and Im sure I can find a code to save $, or Im sure its sold in a Gallon.

Just waiting for the experts here

Thanks for all of your searching!

No problem. What kind of car do you have?

Also 6.99 is a good price for a FULL SYNTHETIC ATF....

However I want someone who knows about the cSt and Flash Point info to let us know how good or how good its not compared to other full syns or if its good for Honda and how it compares to HG DW-1

and how the others ATFs are.

I would actually put 3 QTs of this in my Honda ... I mean it says DW-1 for Honda and Acura. It basically says word for word what the bottle of HG DW-1 says on the back of the bottle.

again just need a tech savvy person to respond.

and no problem, I like to search things out and post pics.

Well, the only thing that I can say with any level of conviction is the Import Multi-Vehicle will have gobs more VIIs than the Fully Synthetic. You can tell by the 200 VI for the M-V and the 166 VI for the Synthetic. They certainly wouldn't use a better base oil for the Import one compared to the Full Syn, so they load it up with VIIs.

Other than that, I see no reason why either one wouldn't be suitable for your Accord. You're well out of warranty and if you'd had no problems with the AT yet, you should be in the clear.

Thanks for posting. I've not yet heard of Castrol's Full Synthetic Import ATF. The specs certainly look superior to their older Transmax IMV. threeputtpar's comments on viscosity index is spot-on in my opinion; we know the older Transmax IMV shears pretty quickly in use, and that's likely due to the very high viscosity index and the number of viscosity index improvers that it uses. Because the new Full Synthetic product is Dexron-VI licensed, we know that its viscosity starts out much lower than an older fluid, but we also know that it won't shear nearly as much with use. The spec sheet confirms that: a starting viscosity of 5.9 cSt (vs. 8 cSt in the older fluid).

So would you use it in your Honda AT ?

THanks for info.

 

[David1]

Did anyone else look at the numbers and see what is the better ATF???

what do you mean by ** gobs more VIIs **

Also what do you think is the better Fluid???

Here's a previous thread on this topic, not much info though : http://www.bobistheoilguy.com/forums/ubb...ynt#Post3146072

Yes but only a few commented about the Phisical aka the cSt and flow rate and Sheer.

Also if you look at my pics it sorta reads like the back of a Honda DW-1 bottle.

I might actually try this.

Im tired of spending 11$ a QT at the stearship.

 

[David1]

Next time I change my oil Im going to drain and fill with 3QTs of the Castrol Full Synthetic Multi Vehicle that says DW-1 for both Honda and Acura....

Im not sure if 3 Qts will make a differnce, but Ill let you know.

Looks like no one else here has tried it and not many have looked at it.


Funny its a Full Synthetic that says the exact same thing that the Honda DW-1 says on the bottle.

anyone have cSt and flow rate and other info on DW-1 to compare to this?

 

[charbaby]

No doubt that the new synthetic Castrol will be the better ATF compared to the TransMAX. Due to it being synthetic and lesser VII's. Also, the new syn seems to cover both the DMV and IMV apps.

Thank you for your response and also I think this might be a be a way to save from having to buy HONDA Genuine ATF DW-1 from the dealer at 11$ per Quart.

However what do you mean by lesser VII's

Sorry I really do not know when what certain terms mean....

Also Im going to use this with my next drain and fill.

What I find funny is this ATF is approved to run in more Toyotas and Hondas and Acura and German cars compared to the Import Multi Vehicle brand.

However my main question is what do you mean by lesser VII's

Thanks you

The comment about fewer viscosity index improvers comes from looking at the physical characteristics of both fluids. The older product had a viscosity index of 200, while the newer product has a viscosity index of 166. A higher viscosity index often means that the fluid will have a tendency to shear while in use. By that, I mean it will tend to lose its viscosity.

There is, of course, more to a fluid than viscosity or viscosity index. In the case of an automatic transmission fluid in a Honda transmission, I have found friction modifiers to be critical to how a transmission shifts and behaves. I have tried all three of the commonly-available multi-car fluids (Valvoline MaxLife, Valvoline Import, and Castrol Transmax IMV). Each one of these behaved very differently in both of our Hondas' transmissions. While I will say that I liked the Castrol product the most of the aftermarket fluids I tried, I like the OEM fluid the best. While it's probably technically inferior to Valvoline's MaxLife or Castrol's new synthetic Transmax in terms of viscosity and base oil, I believe it has the additive package that works the best in Honda transmissions.

$11/quart for DW-1 at your local dealer is highway robbery. MSRP is only about $8 (and that's what my dealer sells it at).

It seems you have asked the same questions before in another thread.

I don't know why you asked about flow rate. The flow rate is determined by the oil pump pressure and pressure is determined by internal pressure regulators. You have NO control over internal flow rate.

All fluids have Viscosity Index Improvers (VIIs) to help the base fluids maintain viscosity over temperature extremes. (BTW, there are hundreds of threads on BITOG discussing viscosity index).

The viscosity of the Castrol Synthetic is 5.9 cSt at 100C which puts into the category of an "LV" ATF, similar to the DexronVI viscosity range.

If the Synthetic fluid covers your vehicle then I think you can can use it.

I hope this finally answers your questions.

 

[MolaKule]

And I would highly recommend you do some reading and studying in the

Science and Technology of Oils and Lubricant Additives » Question of the Day forum such as:

VII

Quote:

And you have no control over the VII as well.

Little off topic. I have considered using Castrol Transmax Full Synthetic instead of Castrol Dexron VI Syn blend is there a advantage to using these multi vehicle ATFs? The Castrol Transmax Full Synthetic cost a dollar less the the Dexron VI Syn Blend too.

 

[David1]

Well i put 3QTs of the Castrol Transmax Full Synthetic and its to early to tell....
I dont want to say I feel any difference b/c that could of just been me thinking it felt better. I drained 3 QTs and added 3 of the Castrol Full Synthetic Multi Vehicle.

In 10K miles Ill do another 3 QTs and Perhaps by then I might have something to report.

Or perhaps after some more drving I might be able to tell.
First time this car has had anything but Z1 and DW-1....

Thanks for your reply's
