I put a 16 oz. can of Sea Foam engine treatment in my 2000 Mazda Protg LX 1.6 and saw no smoke! I didn't put it in oil reservoir...only in gas tank! Do I have to put in oil and gas tank to get full effect of the product...or is it simply BEST to do both?
I also want to clean my engine bay? Have you ever did it and how did you do it? Do I have to cover spark plugs, alternator...or just battery?
