voltamps said:All would be fine in the Nissan Leaf, except the long term gear teeth and bearing wear in our reduction gearbox could be reduced a few thousand miles if you go to the thinnest in the group, the ULV stuff:
Redline D6 ATF: kv100 6.3
Amsoil Signature Series Fuel Efficient ATF: kv100 6.3
Valvoline MaxLife™ Multi-Vehicle ATF full synthetic: kv100 5.9
Mobil 1 Synthetic LV ATF HP ATF: kv100 5.7
Idemitsu Nissan Matic S: kv100 5.2
Valvoline ULV ATF full synthetic: kv100 4.5
Yes lower viscosity does mean more EV range. That would work.
Durability is a concern with the ULV fluids though.
Thank you for posting this summary. I have a case of the AMSOil Fuel Efficient ATF that was left over from my Titan. I plan to use that in the Leaf. I was surprised to see the viscosity number for it was higher than Matic S, so I checked on it. According to the PDF link below (top of page2), the KV100 number is 5.8, not 6.3.
