Finally got a long road trip this week, about 600 miles round trip. Set it on 80 dd, set the cruise at 65, keeping the RPMs around 1800. Only went oner 2000 a few times passing some road barges.
Got 18.9 on the way up, man I love tail winds!
Got 16 on the way back, man I hate head winds. Would have been a good day to drive to Havre, if you're from MT you know what that means
Was driving into 20+ mph winds for the first 150 or so of the return trip, then 10-15 mph winds the rest of the way.
Good mileage all things considered, I think.
NICE!
