Eco mode frustrates me too much to stick it out for 500+ miles.
Highway...I have my doubts if it helps that much. As I mentioned before, if you hit a decent uphill in Eco mode, you really slow down in 8th and you drop 10MPH and have to step on it hard. It'll drop you down to 6th instead of 7th most of the time. With ECO mode off, I've never seen 6th gear on the highway.
Off-Highway, ECO mode will most definitely help. Running through 1st-8th on the highway only happens after tolls and exits....off-highway...its every stoplight and stop sign. Eco mode does a great job of keeping the RPM's low during those multiple starts.
