    The DIC doesn't lie..it does the same thing a calculator does...distance divided by gallons=average MPG..how can it lie?

    You miss the point...

    It is indeed doing a miles/gallons calculation but its estimation of gallons is flawed. I don't know if it uses the sender or metered flow rate or whatever, but when I do the math at the end of the tank the DIC is lucky to be within 20%.

    They're famous for being inaccurate.
