Same here! One of my trips was to TX as well. Well over 300 miles. Averaged about the same, used the cruise control, and was also doing in the 80mph range. I guess the extra MPH really kills the fuel eco. I know on our sedan (which is a gas guzzling V-6 rated for the same MPG as the van 19 city & 25 HWY), even at 80 something averaged 23 on the highway (clearly different vehicles with different weights), but still I find 19 to a be pretty poor showing. Something like 22mpg would be more understandable given driving conditions. OH well, thanks for the feedback.
