Haha, you're funny. I thought it was hilarious when my 2014's oil life calculation dropped like a rock (fell from 8 to 2% in under 100 miles, resulting in an algorithmic oil lifespan of under 4200 miles/6 months). Incidentally, that oil lifespan algorithm bug is why all PCM updates for the 2014's are RRTs.
I definitely place more weight on UOA reports than the "sophisticated algorithm" when that was so thoroughly untested prior to release that it included severe bugs. I still follow the FCA requirements for warranty purposes, but data from my Jeep's UOA satisfies me that there's plenty of life left in the oil even at 12 months/10k miles of predominantly short-hop in-city driving.
