I <3 my engine kill switch.

This was not my most accurate fill. I had a body compressing the passenger side suspension, and the lot was not level.

I'm actually disappointed, since the ScanGauge was telling me I was getting >30mpg every day, and sometimes approaching 33mpg.

The return trip from AMEC. What I'm burning here is a 50/50 mix of Ethanol-free and regular gas, cruise set to 68-72mph, 50% grille block, A/C set to "low" for half of the trip.

The MPG reported here is an overestimate, because the tank was filled very, very full at the last stop. It's probably more like 35mpg.

AMEC Economy Run III. P&G, 70% grille block, tires inflated higher than usual, average speed around 35mpg. 104 miles and only a handful of stop signs. ScanGauge reports 50.0mpg, which was my goal.

Topped off at the ethanol-free Fairway Oil, while an AMEC official watched.

This tank was 100% highway, cruise control at 74mph, no A/C. Early morning temperatures in the 60's, Fahrenheit.

Don't go to the Shamrock at Kensington & Eggert in Buffalo. The parking lot is not level, the staff is not interested in you, and the software is not user friendly. The lot was slanted such that I probably overfilled the tank.

Bicycle season is upon us.

Eventaully, I found I had a malfunctioning ignition coil. Went through ten spark plugs during this tank, while I was supposed to be moving instead of carfixen. I hypermiled the hell out of the Subaru, because its peak HP was somewhere around 35. 45mph on the throughway, major DWB, the guy behind me can wait.

At this point, I'm confused by the upward trend in my fuel mileage, since all I've done since I started logging is add a grille block and slowed from 70mph to 64mph.
