Wow! 859.3 miles on 13.25 gallons for 64.85 mpg. How do you do it Mark?
Do you drive it downhill and then push it up the other side?
I too am "struggling" to get a 60MPG/700+ mile tank. I found Jason's site a year and a half after I got the car, but quickly learned that I had already picked up most of the high-mileage driving techniques on my own, with the exception of increasing the tire pressure, which I did a couple of weeks ago. That seems to be getting me about 2-4 MPG (and the car does handle better).
I'm guessing the main difference between me and you (and the rest of the hi-milers) is speed. What are your typical speeds? I usually go about 3-5 over the limit. 69-70 in a 65, 60ish in a 55, etc.....
But even if I never reach 700 (which I know I will), I will always enjoy the look on peoples faces when I tell them I regularly get (only

) 600+ miles per tank.
And oh yeah, did I forget to mention that I LOVE THIS CAR!!!!. Cheers.
