I concur with the choice of Redline D6 ATF fluid ( https://www.redlineoil.com/d6-atf
). It's Pour Point is -76 deg F, which means they must be using moslty PAO with POE for their base oil, as other Nissan Matic S ATF fluids are typically about -60 deg F using mostly GroupIII base oil. PAO & POE are better for longevity, assuming the antioxidants are similar in formulas. What clues we have, Redline wins.
Also, Redline D6 is slightly more viscous, by about 10%, than most other Matic S ATF fluids available, which is probably better for wear. Also means a small loss of efficiency which most won't notice.
A downside is that Redline only says
its for Nissan Matic S applications like ours. It doesn't officially hold that certification. Redline (Phillips 66) is a reputable company though. My Nissan Owner's Manual (2020 Leaf) has strong wording that we void the warranty if they find out we are using something that is not officially Matic S test approved and a problem occurs. Hmmm, it would be "safe" to simply use Nissan Matic S. Undecided here. I won't need it until a year or two from now anyway.
