I don't have a Scangauge. My car is OBD0.

I did achieve my goal of 40MPG this week. I took a slightly longer but not as hilly route to work.
If you don't have some sort of gauge that is calibrated, how do you come up with .1gph at idle?

I think that is closer to what you get with an original Insight.

My car is a 4cyl 6 speed that idles at 625 rpm and at idle burns .17 gph at 100F+ AIT.
