Wow i read all the way through this thread. Info spanned from the ridiculous and unfounded/supported all the way up to the facts.
I have one diesel tractor in the barn among all the other gas equipment. And being a little on the common sense and practical, I am gonna continue to get the occasional five gallons of diesel I need in a red plastic gas container. if I put diesel in my lawn mower it is on me. :S Sides that container is a different shape than the others (for gas usage) and has Diesel Only scribbled across it.
