I was trying to do a poll and having trouble and ran out of time. We went to see Midway. Great movie.

Anyway, since I didn’t get the poll done, the thread seems to be coming alive anyway.

I agree with Jim Yuhn in part. As a result of the push to make cars cleaner, electronic fuel injection came about. It contributed greatly to lower emissions, but also due to closed loop fuel/air control, engines are more economical and last much longer. No more carburetors washing the oil off cylinder walls during cold starts and many other benefits. Carburetors are just antique devices which compromised fuel mixture.
