So I realized after my last engine oil UOA that my type of driving is considered severe service (cold weather + short trips)
For this vehicle, the dealer first replaced the CVT fluid at 31,068 miles. I decided it's a good idea to have them change it again at 48,466 miles - only 17,398 miles later.
Dealer tried to convince me it's way too early, even though I've been getting random noises when pushing the gas pedal in the last few months.
In another thread 86cutlass307 had a virgin sample of Honda HCF-2 analyzed and the 100C viscosity was 7.1 cSt
Marco620 posted his results at 34,893 miles, which seems better than mine.
Based on this information, looks like it's never too early to change the CVT fluid when doing "severe service".
What I wonder.. is how they found 4% fuel in transmission fluid? This UOA was completed by Polaris Labs.
