Same, started to get weird…
Same, started to get weird codes related to emissions and cylinder failing to turn off, around 130k miles on a 2016 odyssey, checked the oil and it was super low after recently changing it, this all started after the wife went on a little road trip with lots of highway cruising ECO mode. Apparently buildup due to cylinders being deactivated fouls up rings allowing the deactivated cylinders to suck oil. Get a VCM Tuner installed as early as possible on any of these VCM Eco models. I was lucky to catch it sucking oil and not blowing through spark plugs, but if you stop the ECO mode earlier I'm sure you'll prevent a lot. Of course no one ever sees any of this info till the van starts throwing codes
