    Squeeze every gallon...

    IMG_20190910_192546.jpg

    Who here is in the 700 mile per tank club?
    I had a lot of twisty hilly back roads , slogging along in 2nd or 3rd.. ( I need a tighter converter!) On this last tank...
    I'm hoping to be in the 800 club soon!
    Took 35.5 gal to top off.. 20.8mpg...
    Not bad for a beat up ¼ mil mile beater!

    My 4th gen was all over 630-650 on the highway. This 5th gen struggles to break 500 in stock form & daily driving, my average is about 430

    A tune will fix that though

    Can you not get 20+? I'm on 35s and in the mountains and can get 20+ on highway runs.

    What year you running? What size tank you got? Thought the biggest the cummins ever came with is a 34 gal tank?

    2021 2500 68RFE..... I'll just keep the goodies a secret!!!

    I can get close to 20 if 100% highway driving and keep it at 70 or below. For comparison, my truck has 3.73 gears and a live front axle which doesn't help.

    That truck was a R&D test mule / Dyno mule... LOL
    Over the course of 3 years it prob made 1k pulls on the Dyno, wore I don't know how many different turbos , and beta tested and developed slot of software for several major players in the industry.

    In my "normal " 750hp daily driver form it typically had some hybrid 120+ hp injectors and a custom 66mm turbo....
    In that same form is how it also got it's best economy....
    It liked RPM, If I kept it above 2k it was happy, closer to 3 it wanted to start to work, at 4k it wanted to party.
    Proof that people that love to lug the motors don't understand volumetric effiency...

    My best tank ever was 850 ish doing 80+mph from Seattle to Montana and back.

    Triple Nickel motors were the fuel economy Kings if properly tuned!
