Now Beating the EPA

Odometer: 16324.1
Tank Mileage: 680.0
Gallons Added: 16.293
Long-Term Average: 40.7
Short-Term Average: 40.7
Calculated Average: 41.7

With this tank, my life-time average (calculated as all miles driven divided by all gallon bought) exceeds the combined EPA estimated mileage. (41 city/36 hwy for 38.5 combined) My lifetime average is now 38.52.

This tank set several other records: miles driven (680), tank mpg (41.7), 3 tank trailing average mpg (40.67). I also had a commute into work with an average of 47.6 mpg over 25.5 miles including 20 miles of highway. Finally, the estimated "Miles to Empty" after the fill was 711 miles. This was the first time I've seen over 700 miles displayed.

Time Challenged

Odometer: 15644.0
Tank Mileage: 483.0
Gallons Added: 12.342
Long-Term Average: 39.9
Short-Term Average: 40.0
Calculated Average: 39.1

I had a number trips during this tank where I was under time pressure. I still did fairly well, but there were times when I just had to set the cruise at the speed limit and roll with it. I filled early as I didn't want to have to take the time while in Dayton. The great range of this car adds considerable flexibility in the timing of fuel stops. The extra range also allows one to be choosy about the price paid.

Weekend Trip to Pennsylvania

Odometer: 15160.9
Tank Mileage: 604.3
Gallons Added: 14.823
Long-Term Average: 39.6
Short-Term Average: 39.7
Calculated Average: 40.7

This tank was just about evenly split between a highway trip to Erie, PA and my normal ~25 mile commute. I had a pretty good tailwind on the outbound leg to Erie. After the half marathon, I returned home bucking a headwind most of the way. The rest of the tank was normal commute service.

Killer commutes

Odometer: 14556.5
Tank Mileage: 584.8
Gallons Added: 15.510
Long-Term Average: 38.9
Short-Term Average: 38.9
Calculated Average: 37.7

I had a week of commutes where I was running behind and didn't try for enhanced mileage. This is reflected in the lower tank mileage.

I like the segment mileage report I get when I stop the car. I wish this was stored in a location where I could retrieve the last 10 or so segments. I'm a data junkie and making it easier to collect the data would be a plus. Having the car send the report as an SMS or an email would be a way to do this.

One minor item: While the display, and longer term mileages, hasn't reset recently, I am noting that the fuel efficiency bar graph clears its data every so often. I haven't figured out a pattern yet. This is currently in the "that's odd" category as opposed to "that's annoying".

Somewhat better

Odometer: 13971.7
Tank Mileage: 465.9
Gallons Added: 12.171
Long-Term Average: 39.0
Short-Term Average: 39.0
Calculated Average: 38.2

Still below the longer term averages, but better than the last tank. I had a day where I was operating the radios in support of a local bicycle ride. I changed the way I had the radio battery connected to the car and found a place in the shade where I could leave the car off and the windows down.

Almost two weeks

Odometer: 13505.7
Tank Mileage: 601.8
Gallons Added: 16.438
Long-Term Average: 39.3
Short-Term Average: 39.4
Calculated Average: 36.6

Almost two weeks for this tank. This was mostly just a series of commutes. It also included extended idling to provide power for other activities. Definitely not the way to get high mileage.

Three Months

Three months after the purchase is also 13 weeks. I have just over 13,000 miles on the car. At this point I am under 5K/month, but still over 4K/month and just over 1K/week. I am still happy with the purchase and continue to learn new things about the car.

I strongly suspect I will fall below 1K/week by the end of next week as I don't have anything beyond the daily commute planned.
