Jeffro, pumping some diesel, clicks off the pump with 137.001 gallons showing, and asks if we’re similarly OCD:
Just to make it easier to calculate my account balances, I pump my own gas to the nearest dime.
Are you picky — do you “round it off,” or do you just run until it clicks off and call it good?
Weirdly enough, I run until it clicks, and then enough to bring it up to the next dime. And then I go home, calculate mpg, and sob: it’s winter, so instead of my usual 21-22 mpg, I’m barely over 20. In the interest of improving my statistics, I’ve been buying the same grade at the same station for the last several months. I figure I’m taking about a 3-percent hit using E10. Then again, the best tank I ever scored was running the superslab through Midwestern cornfields on 93-octane E10, breaking the 31-mpg barrier. (EPA sticker: 20/28 original; 17/25 revised.)
