Average MPG?

When you mod it all bets are off. My truck is as delivered from the dealer.

 

I've gathered MPG data the past 11 months. My truck is stock and I do city driving 80% of the time - the computer is off by 3.65 MPG from my data collection.
Data shows an average of 19.86 MPG from with a high of 22.15 and a low 17.9.

 

It a still a make a no sense.

 

Does this make it better?

 

Ahhhh... that’s a much a better! Grazie

 

Four a banger?

 

V6

 

The display is on the optomistic side

 

18.1 combined. Stock suspension, 265/70r16 duratracs, leer topper.

 

15-16 mpg city (like 70% of my driving). My tank averages are always around that, I dont believe these people who say they are getting around 20mpg city. I drive like an old man and the best city I've gotten was around 17mpg.
