Tanks 248 and 249 - August 2K10

Last week I managed a pitiful 36.66 mpg, so I made an effort to drive
closer to 65 than to 70 on my highway trips, and today I ended up
reaching 38.17 mpg, after going 447 miles on 11.711 gallons of gas.

It is a remarkable difference, driving just about 5 mph slower. I still
was with the flow of traffic, indeed I was passing a few cars throughout
the tank.

Also, it probably didn't hurt that for about 50 miles I was able to
draft behind tractor trailers.

This is the best mileage I have gotten since I took that class in
Maryland back in May.

For the year, my average fuel economy has been 36.97 miles per gallon on
422.2 miles per tank.

Tank 246 - 3 August 2K10

Yesterday I refueled at an Amoco station near Aquia Harbor, and put in
12.149 gallons of gasoline (10% ethanol, as always) after going 424.3
miles. This made for a fuel economy of 34.92 miles per gallon. Had I
not done the squeeze after the first shutoff click, I'd have been over
35 mpg. Still, it's lower than average.

However, due to a weeklong vacation, it made it 13 days between fillups.
