Inquiring minds wanted to know!
I interviewed the builder via email a bunch of years ago. Here's what he said on that subject:
Quote:
2) MetroMPG.com: Regarding the mileage - 75 MPG - is that a combined total of all driving after the conversion, an individual "best" tank, the "highway" figure, or something else? If it's a total figure, did you get any individual tanks that were higher?
Doug Heffron: My 1989 Metro got 75 mpg most of the time, except when there were a lot of hills.
3) MetroMPG.com: Do you use any specific driving techniques to help with your fuel economy?
Doug Heffron: No special driving techniques were used.
4) MetroMPG.com: What kind of driving did you mostly do with the car (e.g. interstate @ 65+ mph, mostly secondary highway use at 55 mph, or mostly "city" driving, etc.)?
Doug Heffron: Most of the driving was on the interstate.
