When we were moving from the Outer Banks to San Diego, we decided to make it a move/fun road trip. We had to stop at a gas station that time forgot in Nowheresville, New Mexico. I went in to get a drink while my brilliant husband put gas in our Ryder rental truck. I came out to find him letting the gas fall into the tank, the pump nozzle about 3-4 inches above the gas tank hole (I can't think of its name right now. Fuel door, maybe?). I asked him what he was doing, and he informed me that the nozzle wouldn't fit in the hole. Somehow, we had found the last gas station on earth that sold leaded gas, and he had never pumped leaded (regular) gas before, so regular to him was unleaded. I found the mechanic and asked him what was going to happen to this truck that we didn't own. He laughed and said it would run great. Awesome. The truck actually did run quite well the rest of the day. I hadn't even thought about saying anything to my husband about the difference in the gas because it was something I thought everyone knew, so my bad. So, yeah, I remember the post-transition period quite well...lol.
