@punkmonkey123 - I was (screen name Peakster), until I learned how to live without a car entirely :)

@landongendur Well, I, being a lazy american, must live with a car, but 55mpg in my ford festiva makes it a little bit better. :D

@punkmonkey123 - nice! ;)

you can not mesure fuel economy on this level in the real world because there are 2 many variables like wind speed,bumps,overtaking.....

Yup, folding the mirrors will do the trick. I actually did another test video where I got rid of my exterior mirrors entirely (and just had one big interior mirror) and it saved more than 2% in fuel economy.

So if there are no cars on the highway, should I fold in the side mirrors to boost fuel economy?

Km/h is what my original car's speedometer reads. The ScanGauge electronic device on the dash was calibrated to measure gallons consumed/hour and miles travelled per hour.

I like using the miles/gallon equation because it's the standard that Americans (and a sizable amount of the Canadian population) use when measuring fuel consumption.
