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.)
