Today I took my truck on a little trip all 2 lane highway to my 3rd cousins first birthday party. It was 167 miles round trip passing through a few small towns and going from 70mph to 35 mph and back again several times. It has been a few months since I made anything close to an all highway mpg est in my truck so I decided to go ahead and fill it back up when I got back home and boy was I amazed 19.42mpg I didn't get that good of mileage when my truck was brand new and I didn't have 400lbs of tools in my tool box. Just thought I would share this and let everybody know 20mpg in our trucks is deffenitly possible.
Champion
my 97 fullsize with the 5.2 got that good of mileage with just an intake and exhaust. kept a decent tab on mileage until i traded it in for my 05 dak.
It was mostly flatlands going through eastern arkansas. It realy surprised me beacause I know I made atleast 5 wot runs passing 18 wheeler and passed quite a few cars and I was hitting 90-95mph passing the 18 wheelers.
i can barely get over 12mpg now.. stock i was only getting around 13.5
