Hopefully it continues to jump, I am going off the EVIC system as of right now but I will still like to see how it is hand calc.
05Train...your message makes sense, but no matter whether its the last 20 gallons of my truck ran to empty, or the first 20 gallons from the top of the tank, 20 gallons is 20 gallons....so unless there is something huge hiding that I am missing it seems pretty common math to do. I will see on my next fill up what hand calc comes to.
Titans may be different but if you are thinking about buying a tonneau cover solely for the purpose of gas mileage you may want to read this.
