Do i need to add oil when mixing gasoline with seafoam?

[Alex81]

I have a 2 cycle mercury. I think is oil injection. Do i need to add oil to the mixture of fuel and seafoam or just mix seafoam with fuel? Thanks.

Nobody can answer that question for you unless you are sure it is oil injection, you know the oil injection is working, or you know the oil injection has been disconnected (which most have been). Somehow you need oil. Seafoam does not replace oil.
