Use at you own risk - slick 50 , Duralube and such have been on the market for long time but in my opinion if you change your oil regularly with quality oil+ filter you dont need any so called additives.

I agree, some of the oil "additives" may work short-time miracles in an engine for a short time, but in the long run they could cause damage if they form an acidic solution, and some are known to do that.
Best method is to do frequent oil changes every 1000-2000 miles with regular oil that has the current starburst symbol on the container.
You can use synthetic oil if you do not care about oil leaks, or throwing $$$ away!
