Was running a search on UEV's in here and low and behold, I found the uev440 post. Sorry to resurrect, but too bad this thing ain't available in the US anymore.
Using cruse control mixed highway and secondary roads averaged 19.1 on a 420 mile round trip yesterday. Was better than expected. I did see some periods of 22.4 :noidea: on the on-boad display with a low of 16.4 on the trip. The stated averages from Toyota are accurate. Tire pressures are 33...
Can say with complete certainty that Toyota guest give a poopoo about Entune. It's just a fail. As long as you can use the alternatives, you're good to go.
