"as for the gauge, why is that a negative ? extra weight in ink ? "
I don't think that there is anything wrong with the product, it is just a little amusing when the marketing guys can't put together anything really robust, and they are scraping the bottom of the barrel when we hear comments about fuel sipping. The fuel estimation gauge isn't a problem as long as it works, but a digital scale will likely work better.
Much ado about nothing.
