Wow, I can't believe I read all that (including links given) on only one bag of popcorn. LOL.
You guys are all too much. Both sides. Good entertainment.
BTW: How did AFR get pointed out as the mainstay of pollution in engines ? There is a lot more to it than that. 'Too' Lean is not always better for emmissions and/or even fuel economy. I'll leave it at that for now.
Switching topics but still on emmissions - anybody ever see what the effects of volcanoes have on our climate and atmosphere ? If not, do some research and be prepared to get intrigued.
If someone can find out a way to keep volcanoes from exploding we will be pretty well off. LOL.
Yes - I believe we all have a responsibility to be 'cleaner' than we are. Not just emmissions, but garbage and a bunch of other things.
