I just filled up tonight for the 3rd time. I went 701.6 miles and used 9.22 gallons for 76.1 mpg. Both the distance and the mpg are new Personal Records! I also set 2 other PR's today: 91.1 mpg for the trip from my wife's work to my work(9.6 miles) and 84.0 mpg for the day.
Congrats Larry! I don't think this tank is going to be nearly as good as my last one because yesterday I spent a while teaching my cousin how to drive a 5-speed - really bad for the FE! I'm still hoping to get at least 500 miles out of this tank though. As long as I get over 43ish MPG for the tank my 90 day average should rise. I think I'll get one last fill in before the cycle is up.
