So the good news is that I didn't ruin our new car, but the bad news is that I tried to. I managed to get 14 liters of regular gas in the diesel tank before I realized that I was not putting diesel in. Alas, we were on our way to Legoland for the day -- the promised nirvana trip before the students arrive -- but needed fuel for the drive to Munich.
It could be a lot worse ... we could have filled the tank and been driving and runied the engine while on the way to Munich. Instead it just needs to be drained and cleaned, and its only 200Euro instead of 34,000Euro for a new car. I feel like an imbecile of course, and we can't go to Legoland today as we wait for the tow truck and the cleaning, and I have to tell everyone. Plus, we were dropping off IKEA items at the kid's new school (I had done a run to IKEA for them to help get appliances/lights for the new school building) on the way out of town, and so someone from the school had to come to the gas station to transfer the lights from our car into another. Also, have to tell our staff as they will wonder why we didn't go to Legoland afterall. Had to tell Brooke, our new friend, because she became plan B. Now I figure that I might as well confess to everyone! I think we'll go to the Salzburg Zoo in an attempt to salvage the day!
