Exhaust smell; another thought

["Philip E. Barnes" <peb3@cornell.edu>]

It used to be that you could tell if your car was running right by 
the color of the exhaust tips after a long run. A light grey meant 
everything was OK, while a black soot was indicative of a rich 
mixture. I've haven't been able to get that nice grey in a long time. 
Again, new fuel formula?

I can say that my hair and beard are now nicely grey, thank you very much.
