Which outboard engine oil

I religiously run Yamalube and Ring Free in my Suzuki 225 EFI 2-stroke. With about 550hours I have not had any problems as of yet...knock on wood. Oh yeah...I also have a heck of a mechanic that takes care of my engine...Mr Scott Potter from Viking Marine in Portsmouth, RI. Definitely worth the annual long drive down from Newburyport, MA.

Sec, yes you still need to decarbon...I don't recommend any additives if you deacrabon the engine every 50-75hrs. It's simple procedure with 3 gal tempo fuel tank at stated in the link above. Throw a pint of outboard oil in that same mix and you've got the perfect winterizing juice. I have extreme doubt's if any of those carbon inhibitor additive's do any good at all. The worse part of them is people think by using them they don't need to do real decarboning.

Ed, you know I've never seen or heard of one of those the 12 spark plug Suzy's with a carbon problem. I've thought for a long time that extra spark helps for a cleaner burn in the combustion chambers.

And what if I mix the oil/gas in the tank? I need an expensive oil?

I made the switch to Amzoil synthetic a couple seasons ago. The engine seems to run a little cleaner and there's a-lot less carbon build up from Synthetic. Something about the parts running cooler and if my oil pumps dies, having better shot of saving the engine from a melt down makes me feel much better about the decision. I pay $20.00 a gallon, same as I was paying for Johnson/Evinrude oil.
