Do I add Seafoam or Not???

[tomanytoyz]

i use sea-foam in ALL of my equipment,i buy it by the gallons. a little bit in here and a lot in there.not failed me yet.

Where can you get it by the gallon?? I usually buy it in the little bottles 6 at a time @ $7 each. Id like to get it in a larger container

I get it at my local auto parts shop>mazza auto parts<at $45gl.i think i may have also seen it at (murrys) now O'reillys auto parts..
