I know a lot of you guys swear by ceratec.

I came across this, and haven't watched it yet - I'm sure lots of you have, but I figured I might post it for discussion purposes. I haven't used it personally either but it's a subject frequently brought up so it's clearly relevant.

Some results but not the best product he's tested , so what is ?

 

I have seen that one, overall that guy is a bit less than scientific, but does some ok videos - I think for something like ceratec his methods are flawed and it requires a much longer testing cycle more specifically replicating what is going on inside an engine to really tell us anything. I really have no idea if it really works or not and at the end of the day, I just care that it has no negative affects and hopefully has some positive affects that people say they get.

For me Tasos Moschatos (Mr M156 in my book) endorses putting it in engines when he rebuilds, so if he is good with it in there, then worth a shot in my book.
