I can't peg the cars mpg display to any of my driving. It's worthless.

So is Eco Pro and ASS.

I can idle without AC on for 4 hours to use one gallon; .25 gph on guage.

I use a scanguage, and on a 408 mile segment last month at 70 mph, I used 11.85 gallons for 34.4 mpg figured with pen and paper.

On 70 miles of that segment, my scanguage said 42 mpg.

The secret was that it was good weather with almost no AC, and I had a 20 mph tailwind most of the way.

I've also driven 80 mph with headwind and AC on and gotten 23 mph.

I figure I'll average 25mpg over the life of car even with track days or driving fast.

Try to get that kind of mileage and performance out of any other car.
