I've been averaging mid-low 60's MPG lately and have somewhat modified the my route I drive for better FE as well as some technique changes, mostly slower accelerations.

YesterdayI refueled within 500feet of the last bar dissappearing.
I've noticed my car usually has 2-3 gallons left just as the last bar dissappears.

I traveled 721 miles and the pump clicked off at 8.479 gallons.
721 / 8.479 = 85.03 MPG.
The dash said 62.

85 Can't be right. It probably clicked off early.

After work I drove to a station to see how much could be added to the first click off. The distance between stations was 34.6 miles so I figured that used less than half gallon between the two.

It took .84 gallons to click off so I added .4 gallons and adjusted the formula to:
721 / 8.88 = 81.19MPG.

I wanted to see how much it took to completely fill - to top off so I'd click off and wait 10-15 seconds before clicking again, and after about 4 minutes of paused clicking it was full.

I had the nozzle barely past that trap door inside the filler tube and as I extracted it about 3/4 cup of gas drained out of the nozzle down the side of the car and across the ground, all out of a full nozzle. Guess I need more practice at that.

I pumped a total of 2.75 gallons into the tank at that 2nd station.

81.19 MPG? I guess. The dash said 62 and is usually off no more than +- 2MPG however once last winter it said 68 but calculated about 10 less for what ever reason.

Hmmm. Even though the numbers are there it doesn't seem possible. These are Insight figures.
I don't believe anyone "snuck" any extra fuel between fills. No one else drove the car and I've been monitoring my ODO.

Anyway, I'm going for that legendary +800 mile trip this time since my tank is jammed full.

Any ideas? I don't know what to think. I'm not celebrating yet. Guess I'll have to see what the next few tanks do.

In the mean time I've entered my 81.2 figure in the database.
