I posted this before, but when going on any non-local trips that include some highway, use SMART mode. It works better than ECO. I have been averaging 3-4 more mpg on trips since I started doing that. 2024 now has 13k miles on it and overall average has been going up, and is now almost 38, where it used to be around 34 before I started changing modes. This includes all types of driving.
