Which company is best for our automatic transmission?

I have a Skyactive Mazda 3 that has fw6ael which is very similar transmission to Toyota U660

I have 5 questions
1- are ws , fz and dexron vi interchangeable ?

I asked the redline: “At the moment we do not recommend crossing the Mazda ATF FZ as it uses a unique additive package. D6ATF is a suitable replacement for low viscosity WS ATF, closer to the upper end of the viscosity range at operating temperature, as we usually place our high performance products.
The additive package was better suited to Japanese friction materials than the original D6ATF, for a short time D4ATF was recommended for WS ATF applications.

I contacted idemitsu about multi atf, and here is the answer, "
We understand the viscosity of the Toyota ATF WS and Mazda ATF FZ. However, friction characteristics, and the oil's ability to provide fuel economy vary.
We regret to inform you that we do not have the transmission fluid your Mazda 3 that meets the Mazda ATF FZ specification.
We recommend that you use Mazda ATF FZ in your vehicle for the best protection and optimal performance. "

I contacted amsoil because Signature Series Fuel - Efficient on the international website they did not write that fz is compatible, but fz is listed on the US website !!

these company recommend to use there 5.4cst for Toyota ws but not fz : amsoil Fuel-Efficien on the international website only , redline d6 , Hyundai XTeer ATF SP 4 , starkraft atf vi , neste multi atf , idemitsu tls-lv , adrifol 8HP Fluid (grün) , Petronas Tutela Multi ATF 700 in the previous edition , Total Fluidmatic LV MV except in thailand


2- who is the target consumer of 7.2 viscosity since these companies recommend it for fz : for a short period of time D4ATF was recommended for T-WS

Kixx multi but didnt recommend it when i contact them , castrol atf multivehicle , ngn Universal ATF ,rolf ATF Multivehicle ,unitedATF MV-99 ,aisin ATF AFW+ , idemitsu atf , s-oil 7 ، shell spirax-s5-atf-x does not recommend it to T-ws , castrol transmax atf z ,

summary of People opinions to use 7.2 cst instead of 5.8 cst :1- more protection 2- felt improved shifting 3- aisin is the manufacturer of the transmision 4- no one has been hurt from using multi atf 5- viscosity of 6.2 is the sweet spot between protection and fuel economy

3- Why do these 7.2 cst are not recommended for fz : ZIC ATF Multi HT, Eni Rotra ATF Multi , liqui moly 1200 , g-box Far East свежее, Mobil ATF 3309 , Fuchs Titan ATF 4400 , Lukoil ATF Synth Asia , TCL ATF T-IV , ,Wolf Vitaltech Multivehicle ATF , Petro-Canada DuraDrive MV Synthetic ATF , Total Fluide XLD FE , GToil GT ATF Type T-IV , valvoline import , PENNZOIL® AUTOMATIC TRANSMISSION FLUID , PENNZOIL PLATINUM HIGH MILEAGE ATF ADDINOL ATF XN 5 , ADRIFÖL ATF 3309 / ADRIFÖL Dexron III H


4- are these the only reasons that make low viscosity multi atf better than 7.2 cst? : 1- has higher cold brookfield 2- 7.2 cst doesn't match car manufacture fluid who program the transmission and dialed the tourqe converter 3- multi atf companies will benefit more to marketing one bottle and easier logistics 4- to satisfy CAFE fuel economy regulations 5- shorter warm up time

Even Though 1- afton doesn't mention fz in there additives 2- honda dw-1 does not match chemically to most of multi atf 3- non of these multi atf has official approval from mazda 4- its only a recommendation without solid guarantee
5- some of multi atf has half of oem fluid viscosity but they claim the higher viscosity index will make for it

Companies made specific fz but not approved by mazda : adrifol atf fz , ravenol fz , aisin fz 2

sold by mazda dealer : australia by castrol , europe by total , middle east , and usa by idemitsu

Companies merge fz , dexron vi, ws q8oil auto mv , ADDINOL ATF XN 6 , 7 , nulon LV , valvoline maxlife multi ، kixx vi


4- when miles / years to change fz which is group iii partially by drain plug or easier by extraction from dipstick (4.2 to 5 quarts )
-when to change it completely(8.24 quarts) : partially by extraction from dipstick (4.2 quarts )then after 5k miles from removing the atf pan and filter 5 quarts ?
-i live in dry environment with an average of 72F in winter and 109.4 F in summer, my average transmission temperature is 194 f ,
- helpful used fluid analysis from american 2 3 , russian ,
In our environment, major transmission issues start to appear for some mazda viechles if the fluid hasn't been change for 118k miles or 200k miles , rough shifting appear for some after 44k miles of old atf and got 70% success rate after transmission update
- helpful resources about changing interval 1 2 3 4 , aisin afw+ fully synthetic recommended complete atf flush every 20k miles

5- which one SHOULD I use and why?

Prices in my country mazda fz 25 US $ a liter , T-WS 9.5$ a liter, amsoil 15.7$ a quart

What year and what mileage on your Mazda?

Also, what country are you in and do you have Mazda service center/certified mechanics?

And why do you want to/ for what reason do you want to use other brands, viscosities, etc.?

If your reason is only to save money, then ask yourself, is saving $50 extra by using a non Mazda transmission fluid worth the cost of a new transmission?

Don't mess with cheaper fluids on an expensive piece of equipment.

If power train is still under warranty, then use the recommended Mazda fluid from Mazda. Any other brand, type or viscosity fluid could react in a negative way, higher pressures, wear and break down faster, not lubricate enough, cause higher temps, have additives that corrode or clog, and the list goes on. Just use their fluid. It's that simple. Is their a reason you don't want to use their fluid?

As far as interval, do whatever pleases you ...
or contact Mazda corporate, explain driving conditions and ask for what interval they recommend.

If you think your environment/hot climate is harsh on transmissions and fluid, then change it more frequent. For instance, half at 30,000 miles and half at 35,000 miles if you feel it needs changed that early.
Especially if, per your original post that some people in your country have problems at 44,000 miles.

If you are going to mess with dropping the pan, make sure you have proper tools and gaskets/ gasket- maker to put it all back together. Otherwise take it to Mazda certified mechanic/ good mechanic.

Even if it's out of warranty, but still in great condition, would do the same as above. Now if it's out of warranty, has high mileage and the car is not worth much $$$, then maybe you feel like experimenting with other different viscosity fluids or less costly fluids?

As an example,
my previous vehicle was a Ford brand. Used only Ford motocraft oil and atf fluid, during warranty period and after warranty up to 120 k miles, changing it(atf fluid) every approx. 40 k miles or so.
After 120k miles at 8 years old, when no warranty and vehicle value declined, then switched to Valvoline high mileage ATF's and oils. At 195 k miles and 14 years old, no problems with transmission & still shifting smoothly...due to our winter snow climate and salted roads, the frame rusted through before the engine or transmission gave out.
Hence why I now use Fluid film to undercoat my vehicles and prolong the frame/vehicle life.

Mazda FZ appears to be made by a German company, Ravenol? Still, it is a unique synthetic and is not very expensive. I buy mine through Amazon ($18.50/qt). The US manual recommends changing it at 30k miles under a few conditions, like towing. I tow and change mine at 30k miles. There is no recommended change interval unless you are towing, or some similar heavy duty use.

Were I you, and using my CX-5 for commuting and travel, I'd drain the pan and refill with Mazda FZ ONCE around 50k or 60k miles. At that point the price and availability of FZ is irrelevant.

I think you are over-thinking fluid changes.
