After replying to another post about diesels, it reminded me of a story I recently read about a new "envirodiesel", that makes your exhaust smell like french fires. Some company has developed a way to turn old vegitable oil from resturants into a hybrid diesel fuel. They say it does make your exhaust smell like french fires. Right now the immediate downside is that it cost $3.15 a gal. in San Fransico. I forget what they said it does for your fuel economy. This article was put out by the AP, so I assume other papers got the same story. What also makes this story funny is, a while back someone started a thread about what can you use in a pinch if you run out of diesel. Someone said they heard of someone running into a grocery store a buying some veg. or peanut oil.
I can see it now, us diesel owners will be indirectly helping McDonalds sell more food. We'll be driving around giving everyone behind us the cravings for fast food.
