    It’s a really bad wild ass guess the computer gives. It’s based off the average MPG’s your computer is reading. You can reset the avg mpg by prettying set until you display the average mpg’s and then hold it to reset it to zero.

    don’t know what to tell you then, try less skinny pedal maybe?

    I’m averaging 15.5mpg (based on fill up and mileage) so I’m figuring 350 miles before I’m bone dry in the tank.

    You can stick a LOT more fuel in after the nozzle clicks full. I cram the shit outta mine after the nozzle does the first click "stop", a lot more. ,.. and have yet to ever see any 400 mile range on the screen.
    Mid 300s most I've ever seen. It will base it off what your averaging. Real time, your range will be adjusted by fuel at hand, and what your averaging at the time.

    Apparently this is a bad idea:

    You can "Reset" your dist calculator by pressing and holding the mode button on your steering wheel. Also, by cramming fuel into your tank, you can flood the evaporative charcoal canister. It is designed to absorb excess fuel vapors from the fuel tank. Not a cheap repair. Never keep "topping off" your tank after the filler nozel clicks off..

    While the meme was very convincing, do you have any actual data to support your cynicism? I'm genuinely curious, since I have heard from countless sources that topping off modern gas tanks is a very bad idea.

    I think your assumption as to where the gif was directed is wrong. The gif was at the response I quoted and the “probably what your link says...haven’t looked at it yet”.

    The articles are really well written and descriptive. I say articles because in the comments he provides a link to a second part on it. I knew overfilling had an affect on the crap system but wasn’t sure how and that article spells it out pretty damn well.

    375 miles is typical on a 5th gen ..same on my 2016 with all stock tires etc..

    when to cold temps hit it does drop down .. lower MPG in 35F and lower temp..

    from what i read on the forums
    the on board Computer takes your driving average MPG and calculates an estimates of what you would get on a tank full of gas per your driving habits but I can tell you its not so accurate
    thanks to every one.

    if you drive in the city and speed is variable then not accurate as the computer will indicate different miles to require fuel.

    so you on a trip, hywy speed same the whole trip , then it is pretty accurate.. I have this work good when I do my 1700 mile drives to florida.
