I recently put on one of the Sigma digital speedometers and have been running with it this week.
Besides being able to tell just how fast I've been driving...
I also learned that adding up your trips in your head and calculating your fuel economy isn't incredibly accurate.

So I filled up this Tuesday and drove all week. With a couple side trips to the grocery store & whatever the trip meter said 137 miles as I pulled in to fill up this afternoon.
That's way more than I would have guessed, due to not really adding up all the little places I go during the week.
It took 4.3 gallons.
The Sigma also records top speed, for the week it was 78mph.
So pretty much driving like a madman and taking a lot of little short trips I'm getting 31.86 mpg. I wonder how good it would be with a rebuilt carb? I wonder how good it would be if I could drive 55? The world may never know...
