I think the average MPG on my dash takes into account about the last 500 miles or so, currently its at 23.3 but I've done a fair amount of highway miles in the last week.
I have done mostly city driving myself due to the short commute that I have these days. I have averaged 18.5 to 19.5 mpg for my weekly round trips to the office. I made a trip to Lake Charles Saturday and returned to Houston on Sunday and I averaged 23.6 on the highway and most of that was 70 to 75 mph driving due to the recent speed limit changes. I imagine my next trip to New Orleans will be 25 mpg or better. It generally takes me three weeks to need a to gas up up and I generally do that with a quarter tank remaining. My truck came with the 32 gallon tank. I generally put 25 to 26 gallons in at the pump.
