I just started reading the fuel additive posts and did some searchs and found many things interesting. The only experience I have with adding anything to fuel is Seafoam, which I use on my lawn & garden stuff and in my 2 stroke carb Mercury outboard. It's worked wonders on my 2 stroke applications but I was wondering what would work better as a 'maintenance' additive for my new auto's and EFI 4 stroke ATV's? Also, what are the pro's and con's to Seafoam? I don't see it pop up to much in conversation except when people use it in their oil.
Thanks in advance.
