thats what I do...keep reciepts and just write down at how many miles I filled up and I let excel do the rest.

The last 2 tanks I've used were around 10mpg lol. Then again I'm running on E85 and fill up the tank for around $50. And the fact that I went to the track on the first tank didn't help much with fuel economy.

drive in ect snow mode
never go past 2k rpm on the surface streets and never past 2.5k rpm on the freeway (~65mph)

it's definitely not fun, but i save quite a bit of fuel this way.

Here is more info:

hmm.....42 gallons of gas; or that scangauge?



i think id rather spend the 170 on fuel itself and bother with doing the math every now and then.

All of the features of the ScanGauge seems interesting... Has anyone seen or used on first hand?

I got 22.5 through my first full tank in a 400. Probably 2/3 highway at 60 and 70 mph, not getting on it too hard in town.

Funny... my 2GS's MPG gauge is spot on.

NAV FTW.

I got over 400+ on a full tank going over between 70-75 mph.
From where i live to ATL, is over 400 miles and my gas light came on when i got to the ATL area, which also means i can go a little farther if i wanted it to, if i wanted to completely run out
