I believe Nissan charges $40 a quart or something even higher.
The Nissan stuff is somewhere in the $15-$20/qt range. Not too bad.
Considering that Nissan extended the warranty on these units to 10/120k, using an aftermarket fluid is not something that should be done without some thought.
What color is this fluid? Does it at least match the same color as the OEM fluid?
Despite the wear comparison on the page, I am still a bit skeptical of this fluid given the wide range of applications that it is suitable for.
CVTs live-and-die by the correct fluid -- the belts are HIGHLY dependent upon very specific frictional properties in order to survive.
