New record distance!

[PaleMelanesian]

I just beat my distance record! Thanks to an excessively hot summer, among other things. It took 7 weeks of commuting, 10 miles at a time. I started with the tank topped off until gas was sitting in the filler. I ran it down until it sputtered and died. A gas can (2.000 gal) in the back got me to the station for the rest of the fill.

1133 miles
13.751 gallons
82.4 mpg

Mods:
Grille block - smooth upper, 3/4 lower to leave a little airflow
Tire pressure - high
Mobil1 5w20 oil
Scangauge
Battery trickle charger. Too much EOC runs the battery down. 0.74 kwh for the tank.
A highly adjusted nut behind the wheel.

Techniques:
P&G EOC
conserving momentum
light timing
route selection
low speeds
low rpm shifting
parking at the uphill end of the lot, facing downhill for a rolling start (I enter at the top, so I just stop there)
NO AC

Good for you!!!!

I just wish I could get that high. I might have to try it some time....

Incredibly impressive.

I've probably asked before, but what is your commute like?

[PaleMelanesian]

My commute:
10.6 miles total, 3 stop signs and 5 lights.

~3 miles of back country 2-lane with rolling hills, some steep enough to require 4th gear. 35-45 mph limits. 3 stop signs, very little traffic.

~4 miles of 3+3 lane 55 mph, with 3 lights. Traffic can be busy, but with three lanes, I have freedom to drive as I please.

~4 miles of 35-45 mph suburban 4-lane, 2 lights.

Work is slightly lower elevation than home, so my morning trips are a bit better. 90 mpg vs 83 home.

It's a pretty good route. There is a shorter route, 9 miles, but that's all 55 mph 2-lane. I have to drive faster for traffic. I can get 70 mpg on a good day. The longer route uses less gas as well as letting me push some ridiculous numbers.

Holy cow! That is awesome!

Thanks guys!

The Scangauge was a little high this time. I believe it's the E10 that messed up the calibration. I've been running straight gas, but we just lost that option in this area. 83.9 on the gauge, 82.4 actual.

I'll likely not be pushing it this far again any time soon. My mpg drops at the end of a tank. It gets tricky to restart the car, due to poor fuel pressure, so I use more engine-on coasting instead of off. The tank was at its highest of 84.8 mpg 100 miles earlier. If I can't beat the distance, it's better for me to fill sooner and use less fuel. Also, less possibility of stressing the dry fuel pump.

Very impressive tank, a great accomplishment!

That's incredible numberage man.

One thing though, I think the scangauge might be properly calibrated. If I top mine off all the way to the filler cap (I do this for 500+ mile trips) the scangauge calibration% will read a bit off because you essentially filled up what it sees, and then filled up the gallon or so extra in the filler neck and whatever else you could squeeze in the tank, instead of the first click that it usually sees.

Anywho, that's amazing, 1100 miles from a nearly stock civic is a testament to how much driving style changes mileage.

[PaleMelanesian]

My previous two tanks were also topped off and run down to dry. 1108 and 1114 miles on those. I used the same pump even, only now it's dispensing ethanol. My calibration hasn't changed in over a year, and it's been accurate or 1/2 mpg lower than actual, until now.

Good job!
