SeaFoam vs Lucas Oil

[vomeisentor]

OK, I am about to clean up the engine on my STIHL FS110R, how do I use SeaFoam for this machine? And also why not use Lucas product ?? Pros and Cons ?

I've heard people swear by sea foam and how well it works. I'm not sure how much you should put in the tank though. I would just read the label and go by their recommendations.

As a preventative, use a better 2 cycle oil such as Amsoil or Opti-2. Synthetic two strokes have less smoke and less carbon buildup on the exhaust port. That and the cleaner oil will leave less residue in the fuel system.
