I don't think that'll be too hard.

If you're able to hit 30mpg using a scangauge (totally feasible, BTW) then you'll be saving a lot of money.

So lets say you drive about 1050 miles per month (reasonable according to your fuel log)

At the EPA rated 21mpg, you're using 50 gal/month. At the current Texas average of $3.11/Gal you're spending $155.50 every month on gasoline.

If you continue you're current level of driving, with no scangauge, at 25mpg, you'll be spending $130.62 every month.

If you get a scangauge, and (conservatively) are able to achieve 30mpg, then you'll be spending only $108.85 per month on gasoline.

That scangauge isn't looking too expensive now is it?
Versus the EPA rating the SG will pay for itself in 3.5 months.
Versus hypermiling without a SG, the payback period is 7.3 months.
