While we're on the tank of gas subject, I typically keep mine topped off. One late night a couple of weeks ago we were coming back from a 150 mile stretch from jobsite. We'd spent the entire weekend plus Monday running 12 hour days for a bank conversion, spent Monday running to the locations and cutting off plastic wrap for a reveal. In any case I was exhausted and on the brink of 'should I be driving' territory, so I cranked up the radio and dropped the windows on my way home. Coming up on the last exit for 10 miles I realized I was below E, by how much I have no idea. I managed to get to a gas station just fine, but I figured out that instead of the 25 gallons my owners manual says, and instead of the 26 gallons I know I can put in it, I put 27.5 gallons in! I'll be giving the wife some slack for a month or two after that.
