    My 2018 is currently showing 12.1MPG. Stock tires and wheels too. Maybe that'll make you feel better

    Just basing MPG off the trip per fill up. I have heard about changing tire size in the computer, but need to do more research. Also wondering if a tune could possibly help. If it is what it is, I'm fine with it.

    If you notice your speedo is off or incorrect, your speed will be off, your mileage traveled will be off, but your fuel usage might be a static number. The whole mileage equation would be off then. If the mileage is off, you cant even hand calculate that. I'd start with verifying that speedo. If its off, maybe your worries are not much to worry about after all.

    And this is coming from someone who's speedo says 70 when he's actually doing 74. I look at my mpg and could care less. I put gas in every other week in a 36 gallon tank. It is what it is.

    That's how mine is. And using the adjusted formula for figuring out mileage, you could safely add 1.3mpg to whatever your readout is displaying and be fairly accurate.

    What? You're running hooligan tires?

    I always took you for being well mannered and by-the-book.

    Oh, I absolutely HAD to! Look at how much better the truck appears by just changing the tire and size:
