Last night we took the Highlander to the next town over to eat out with bro in law and his daughter- 4 adults and one child.
I had to fill up the gas tank, so that was a little extra weight also. I reset the consumption screen just to see what I could pull off mpg wise for the trip.
30.3mpg 34 miles total round trip distance
I'm pretty happy with that. I can't think of any other trips that I have gotten that high mpg.
