I have a Saab that takes 3309. There were multi-vehicle synthetic fluids a short time ago that were close to the 3309 viscosity, but now I find most multi-vehicle fluids to be Dex VI clones and consequently thinner. Today I mixed Castrol LV synthetic with their multi-vehicle import, 50/50. In theory the mix should be close to 3309 in viscosity. Any opinions?
Mixing atfs to achieve a target viscosity

Buy the right stuff. Don't play Mr. Chemist. Your transmission will reward you if you buy the right stuff.
The Toyota dealer here sells Mag 1 ATF in their parts department right along side of the T-IV. Priced at $3.99 per quart.

More importantly, the transmission might give you four figures worth of punishment if you get things wrong.

More important to minor changes in viscosity, is the friction characteristic of a transmission fluid. That includes ATF, THF, engine oils and TO-4s, all where wet clutches are present.
Automatic transmissions are rarely at exactly 100C where the viscosity is published. My pick-up truck has a transmission fluid temperature gauge, and I was surprised to see how cold it runs.
Your mixing experiment is no different to someone adding a couple of liters of ATF into a transmission that was low on fluid. Nobody would drive all over town looking for the same brand that dripped on the garage floor.
Case in point; My Allison 1000 came FF with Dexron VI which I changed out @ 75K KMs to a thicker TES 295 fluid. The refill took 9 liters. The torque converter holds 4-5 liters that was left behind. Both fluids must be compatible with the transmission's frictional requirements.

I recommend no one take advice from this person. Low viscosity ATF is not compatible with 3309.

Well, Maxlife and Castrol multi, synthetic lv say that are suitable for Toyota T-IV applications. I'm dubious to an extent, that's why I mixed in a higher-viscosity compatible fluid.

Why not just buy this: https://www.amazon.com/Mobil-55221-Autom...ywords=3309+atf
You would be absolutely certain that it meets specification. No guessing.
What advantage does "synthetic" ATF have over this fluid?

ET16; I hope this download with all the cross references helps. SFU means suitable for use.
Dura-Drive is a "high viscosity" atf, and may be used where Dexron III-H was recommended.
Dexron III-H may be replaced with Dexron VI for improved economy, cold performance and fluid life.
Sorry about the baseball game.

If it helps, I tried Valvoline import multi vehicle in the Volvo XC. This stuff: http://www.valvoline.com/our-products/au...nsmission-fluid
Bought it in jugs from my local AAP. Did a complete flush. Car shifts great. With a viscosity of 6.9 @ 100C, it's pretty [censored] close to the Mobil 3309 of 7.1 @ 100C.

Looks good to go Astro 14, I bet the additive package is either standard issue www.lubrizol.com or www.aftonchemical.com
Yeah, I decided to try the Valvoline because; it's available locally, cheap (in the jug size, anyway), claims to meet JWS-3309 and DOESN'T meet Dex-VI, or WS. Valvoline claims a synthetic base, but that doesn't matter a lot to me because the fluid gets changed (cooler line exchange) every 30,000 miles.
I will admit that I am a little leery of anything that meets every specification...

I agree. I can't find the Valvoline import multi vehicle in the gallon jugs anymore where I am. I'm looking into Shell Spirax S5. This seems to be the closest to a 3309 synthetic.
