17.15 MPG Average
Here's a shot from back in November of 2013
This is my current log
The 20mpg plus trip was with the stock tires at 70 mph the whole tank driving from Toledo to Georgia. I lost a few mpg's with the 265/75 All-Terrains. Everything else is pretty stock. No cold air intake or exhaust mods or anything.
Looks cool, I do a lot of these calcs manually. App name?

The full version costs $2 something. The only thing I'd change about it is the fact that it doesn't have any sort of cloud backup. I use it to track all my expenses along with the fuel tracking.
The ac myth has been debunked a few times it does not change gas mileage nore can you get better mpg with the windows down.
But you will get less mpg compared to the same trip in winter, because driving with the windows up is more efficient then both windows down or A/C. And heat is just waste BTU's from the engine plus minor alternator drag due to the fan.
I always get better gas milage in the summer doesn't matter if my windows are up with ac on or down. It may be due to the gas also though in the winter they add a lot of ethanol to there tanks.

No you won't, because winter gas is formulated differently and nets fewer MPGs.
Between 22-24mpg consistently, Winter is is 19-22mpg, i do a fuel filter every oil change, and spark plugs once a year. I have a 33 mile commute each way doing between 45-70mph, I run 245/75/R16's, with a 99 V6 5 speed and 4x4. Technically my hubs are always locked so i have an additional drag compared to the rest of the 4x4'ers here (i have it wired this way, dont ask). My 97 4x4 5 speed did 19-22mpg year round on the exact same commute with the same tires, so it must vary from vehicle to vehicle.
WHAT? how often do you change your oil?
