Ill be interested to see where this project goes. I understand the haters honestly- its frustrating when they see a big truck mention 30mpg since they may have similar totals
but over an entire tank. To them, its a misrepresentation since they know the truck cant do that well over a whole tank in the same conditions as theyve driven their eco-friendly ride. At the same time, I think the OP laid his intentions out clearly. Cant we all just get along
Prolly even moreso the case with the F150, but wind, hills and start/stop is a murderer of truck mpgs. Ive got a little 4 banger manual supercab ranger- it gets right at 30mpg at 60-65 flat pretty easily. First time I broke 30 was this trip im on now where it turned in 31.3 over ~500 miles. But that was all highway...
When im in town in Austin, my mpgs are closer to 23mpg. I have no doubt the winter will prolly bring it down to 20 even.
What is city and highway really? We can safely say highway is long periods of cruising, but what is city exactly? If im stuck in traffic jams with the A/C on going from stop light to stoplight with not even a mile in between them, I doubt my Ranger would get 15mpg- the weight KILLS my mpgs. Even city driving means some cruising in stretches with no lights (or green lights), or "highway-like" cruising. My truck will get 25 hwy if im riding hills in hill country (if I did EOC I could bump that up im sure)- again due to weight.
Im sort of babbling here. I guess where im going with this is we have to understand that a poster with a truck really needs to focus on highway as a barometer for how well mods work- trying to do it in town even with an in depth fuel log has so many variables he can get lost trying to discern what works and what doesnt.
