Steady state 70-75 mph is where I get 20 or so. Try setting the cruise for a 20-30 mile highway trip and see what you get.
135 mile trip today, 75-80 mph depending on speed limit, and I averaged 19.9 mpg. That included about 10 miles of in town driving which dropped it from an initial 20.5 mpg. I just cruised but did punch it a few times. Can't help that, merging behind idiots going 50 in a 70 zone.
