Finally achieved EPA highway MPG on my wife's equinox. EPA say 32, I got 32.8 between Akron OH, and Chicago IL. --at 70 mph.
I left the cruise on, but altered the speed. As I climbed a hill I would back it off 1-3 mph to try to keep it in the highest gear. On decents, I would go 1-3 over keeping the trans in the highest gear and mpg high.
I was impressed with 32.8 from a largeish crossover loaded for the weekend
