DH and I have had fights about this. I swear I will run on fumes rather then put less then $5. in the tank. If I run out for a minute or go to pick up a kid and realize I'm super low and have no money on me, no purse, I always have a couple bucks in change in the dish. But I am very embarrased to get less then $5. DH has put in $2. all in change.
Recently I put in as little as $3 because that was all I had on me in cash and the pump wasn't taking credit cards for some reason.
But back then, $1 paid for almost 2 gallons of gas, sometimes more than 2 gallons.
