With just 3000 miles on Blaze I think she is still getting broken in ;-) Plus I am definitely having way too much fun with the ponies....and that is still with stock everything. I have sofar seen averages of 23-25 mpg. But that could easily be improved if I was willing to slow down. $2.35 to $2.45 is what all that fun costs per gallon.
Still better than the $3.15 for avgas and 48 Gallons a fillup :-)
