I THINK you knew I was kidding, I hope.

Sometimes, I can sound too serious. (I blame it on my Wife - Janet will say, with a perfectly straight face that something totally hideous is "beautiful", and, because she's much more artistic than me, I'll believe her)! :o
I DO think you've opened a productive discussion topic and I hope I didn't derail it. I absolutely agree with all the points you made, and I just wish I knew more about the subject so I could contribute! But, what I know about diesels, you could put on the point of a pin.
