Well, I just fill up every time and right down the mileage, $/gal, and 
number of gallons.  Then go calculate the mpg.  I keep it all in my 
PDA.  I have records for Sophy from 10/2002 til now.  I had it from her 
first tank full after I got it back on the road in February 2002, but 
lost the early data, including the data from the trip to Parma, in a 
PDA crash. 8^(

Anyway, I average around 24 mpg, with a low of 15.4 and a high of 28.8 
for the data that have.  I seem to remember one tank full on the trip 
to Parma with 32 mpg or so.  Stock in my head because it was better 
than Keith's best with his FI vs Sophy's dual carbs.  I think we had 
pretty good tail winds and some long downhill stretches on the tank.

One of these days it would be interesting to plot out the data and see 
what it shows.  I will have to see if I can import it into Excel from 
the PDA.  I do it for all of my cars.  It is a good indicator if 
somehting is going on with the car.  Often before other symptoms show 
up.
