Amsoil DCT Fluid - Dia-Queen SSTF-I Equivalent
Hey all, got an email from Amsoil today about their new DCT fluid. My '11 RA is at 30k miles, which I think is right about time to flush/change the SST for the first time. I've been procrastinating because of the astronomical Dia-Queen cost. Any thoughts on this new alternative?

You have an expensive and finicky transmission. Use OEM fluid. It's really not that bad. 2 containers is about $300..

I don't know a single experienced and reputable shop that does SST's that reccomends anything other than OEM. Fred beans parts had the best prices usually on diaqueen. I always wait till their 10% off sales and buy up a few cans even if i don't need it. I change my fluid 1-2 times a year (i track a lot), and so i always like to have a few cans on hand for when i need it.

Dealers outside of the USA in some countries use Castrol BOT 341.
People are going to say only use OEM, that the formula is different, everyone is going to have their opinion.
If you have access to OEM I would get that, or your next best option the BOT 341.

BOT341 and Transmax dual are both identical I believe. However neither is available in the USA. In the USA we have to use OEM from Mitsubishi.
I've given up trying to stop people from having to spend thousands to fix a transmission because they saved $100 on a fluid service. They don't listen, and I'll just fix it when they burn it up.

I agree OEM has been the best but this is the first time AMSOIL has posted that they have a fluid for the SST. I always buy amsoil for everything else unless they recommend something else. I wonder if they made changes to the their DCT fluid and is now able to support the SST with no issues. It would be interesting to find out.
I was actually surprised to see the SST covered because I always buy oil from them and they never supported either the evo x manual or the SST.
I personally think amsoil products are better than the regular stuff you can buy out there. I wonder what we need to do to get this tested and see if amsoil can actually support the sst. I'm not about saving the $100 because even if amsoil cost the same I would go that route. Either way I would love to find out.

Diaqueen 90wt gear oil is better than Amsoil gear oil. Has higher EP additive content...lol. There motor oil is great, and I run their trans fluid because it shifts the best. But I don't run their gear oil. My car gets Diaqueen for that.

I just emailed amsoil to see what they say about how they came to recommending the DCT for the SST out of being curious.
I run diaqueen also. Amsoil don't have a recommended one for the evo x:
Differential REAR
Limited Slip Differential, AYC Dif. Mechanism....GLS27 All TEMPS....
No Recommendations
NOTES: (1) Mitsubishi Diamond Queen LSD Gear Oil.
Thats one thing I like about amsoil. They usually don't recommend their stuff unless they know it will work well. I can't wait to see their reply. My SST is already slowly starting to slip and have issues and I plan to upgrade it, hopefully next year. Maybe I can be the guinea pig for this. lol...

looks like red line offers sst fluid, and lists Mitsubishi as compatible. honestly a big sign to me, as they are very, very particular in which OE fluids they are compatible with

what I did when I tested gear oils was I sent in samples of virgin oil - fresh new oil that hadn't been used. sent in samples of red line, amsoil, and diaqueen - that will give you a rough estimate of what kind of additives each fluid uses. then I picked the one that was like OEM, but with more.
