Joe, again, a interesting spin you have spun. I don't know that much about diesel fuel, but now that Ultra-low sulfur diesel (ULSD) is available, maybe some of the European Car Manufactures will re-appear lets hope. I remember watching Le Man last year in the wee hours and they had British commentator's from Radio Free Le Man. They were talking about the diesel Audi and diesel's in general in Europe, then they said, and I paraphrase, "and you in America, you can keep your Prius (hybirds) and oh, by the way, where are you going to bury the batteries. We'll keep our diesels that are getting 40 to 50 MPG". Not sure if they were talking about a imperial gallon, 4.5 Litre verses 3.86, but still not bad. Anyway, enough hi-jacking.
