So this friend of mine borrowed his cousin's Smart For Two for the weekend. It runs on biodiesel. And there are these caps on both the left and right side of the car. I guess you all know that fuel goes in the right side, but he pulled up to the gas station and filled a little under a gallon of diesel in the left side. I guess that's for the air filter and stuff? The car won't start right now. What should he do? He's waiting for the air filter to dry out and try again.
