Is Sea Foam Marine better for my small engines than the regular Sea Foam? [SOLVED]

Thanks for the question! Marine PRO is safe and effective in your small engines and it’s similar to Sea Foam Motor Treatment in that it cleans fuel residues and varnish and stabilizes fuel. You could use either one.

If you want a formula that’s made for tougher fuel residues and varnish, give High Mileage a try in your small engines. That’s my favorite of the Sea Foam fuel treatments and what I use in just about everything. It stabilizes fuel as well.
