Had the second fluid change come up recently for my Accord's CVT. The factory fill was changed in 2017 at 51k by draining and filling, and I had it analyzed at that time. A single drain and fill changes about half of the fluid (3.9qts). There are some who advocate doing a 3x drain and fill (with some driving in-between changes) to more completely change the fluid. I was curious to see if this was really warranted, so I had this second change analyzed. It's only ever had Honda HCF-2 in it. [Linked Image from i.imgur.com] So there was about 4 qts of the original factory fill still in circulation in the above analysis, and with the latest drain and fill, I guess that's down to around 2 qts now. Any reason to do additional fluid changes other than having the effect of draining and *not* filling my wallet? There are only a few other UOAs of HCF-2 on the board, and I think this one has shown the most shearing. A VOA on the board showed the 100c viscosity at 7.1cSt for this fluid. A little concerned this will get even worse when the car reaches ~150k miles, but unless I'm noticing an issue driving-wise, is that even a valid concern?

I would just replace every 25k and be content. I change mine every 10k with castrol transmax cvt fluid just for piece of mind and I bought like 80 qts on clearance.
