    I'm not quite there yet, because I'm still working out bugs on my "Leading" car (the one that will be for daily driving), but when I start road tripping what I plan is to fill the tank until I can see it in the filler neck at a known start point I can find on a map, then drag out the first fill up to another place I can note on google maps and record the amount of fuel it takes to refill to the same point.

    That way I'll have an exact set of references. The exact road distance, and the exact fuel quantity from a certified vendors pump.

I know these differences are slight, but do make a difference and you need to make some long runs to establish the "slip"( a nautical term that includes trailing sea and wind conditions for observed miles vs. engine miles). I always want to know that figure along with determining speedo error, but maybe I'm just anal like that.
    We have odometer test sections out here. I use those and calculate off that, then when i use different tires i calculate based off difference in circumference. But even when your careful there is a decent difference between full tread and bald on the same tire. You just have to choose to not be that picky, lol.

    Better than my old Sporty, but is the same as my Honda Goldwing. My BMW only gets about 28mpg.

    We were just talking about this today at work during lunch. I told the one guy I got about the same MPG's with my formally owned Honda CB750 as I do my Festiva.

    Looks like for the most part the ones with bigger engines get the same or worse and the ones with smaller engines get better?
    Remember they make a lot more power than we do with our stock motors
    I get 46us mpg if i dont take it easy and thats probably 20% city driving by distance, but 60% by time :/
    Also 70-75mph when on the highway. Fuel milage numbers for the highway are quite often calculated at 90-95km/hr with cars, not sure about bikes.

    what kind of gas mileage are you getting with your festiva?

    Check out this link:

    Looking down the list - many of us can honestly say that we get better fuel economy than a MOTORCYCLE, but our stuff stays dry....
