    I just got a 17 international Lt with Cummins automatic. The issues I'm having is:

    1) it has 80 gal diesel tanks. I be having to fill up 2 a day. Is that normal? Is there something wrong?

    2) the engine is on and this is the code that pops up (sa0 spn 2659 fmi 10 oc1). Something dealing with egr. Anybody know or experience this?

    3) when driving gears 1-9 shift normal and drive normal. Soon as it get to 10th great the truck stays shaking talk bad. When I down shift to 9th it stops. What could be causing that?

    As far as number 1, have you been checking to see what your actual fuel mileage is. Like miles divided by gallons filled equal your mpg? Even at 6 mpg you should be able to get 800 to 900 miles on full tanks.
    I get that code on the 2019 LT I drive sometimes when I have to idle the truck when I sleep. Usually goes away on it's own, but the shop has had to put it on the computer to get the light out once.
