"Irregardless," My optimism for insanely high gas mileage for this tank was tempered somewhat when the pump pumped in 10.945 gallons of gas after I had gone 433.1 miles. My mileage was 39.57 mpg. This is better than most other tanks this year, but I hit 40 mpg just last month, although I was rightly concerned that it was due to a pump that shut off too soon, as the next tank was merely 35 mpg.
I had forgotten about the odd pump irregularities surrounding that tank last month, and the other time I hit 40 mpg this year, the tank just before it showed unusually low mileage of 35 as well. So if my next few tanks are consistently in the high 30s like this one, hopefully 39 or more, it should support my idea that plugging these holes improves aerodynamics and fuel efficiency.
So, my mileage for the tank was pretty good. I think it was very good, in fact, because one day I did drive home with much enthusiasm in my right foot, with swift starts and pointless passes of slower cars on twisty back roads. I'll focus on driving more normally for the remainder of this tank to see if the mileage remains close to what I just achieved.
Turns out my daughter needs to do a science fair project, and she was listening to me as I described what I am doing. She asked if she could use my data for her science project! On one hand, I am excited that a whole science project will revolve around my detailed recordkeeping and mileage data, but on the other hand I'm sad that my daughter clearly is taking the easy way out because with this project a whole bunch of historical data has already been collected.
On the bike front, I rode a century ride last weekend with my friend John. Bike time was a little over 7 hours. If I can do two of those next year, that will help tremendously with my goal of riding on my bike for more time than driving in a car.
