a redline a day keeps the carbon away.

both me and my best FC friend high rev our engines once a day, usually before parking them for the night and i have pulled the plugs before and after, and there was noticeably less carbon on the plugs after a good redline, not under load just in neutral. thats my experience, and its done me good to this day. dont know about seafoam as a carbon cleaner, but i have used the aresol seafoam many times to find vacuum and exhaust leaks.

I heard GM Top End Cleaner is better than Sea Foam. You can get it at GM dealerships. It is the same application as Sea Foam and will smoke screen you neighborhood.
