Fuel additive - Stabill, STP, PRI-G, SeaFoam

[HenryD]

Hello,
Setting up a new Suzuki DF25ATL2. I cannot find ethanol free gasoline where I am, so I am wondering, what fuel additive should I use?
The dealer recommended STP, which I had not heard of before for an outboard.
Thanks

Stabil marine has worked very well for me

I've used Stabil Marine but am partial to Startron. I'm using non-ethanol gas now, but still use it anyway. I've used Seafoam to treat a number of engines, clean out the combustion chambers by dribbling it into the intake and going through a soak. Lots of smoke involved in the process, but it works well. Haven't done that to my Suzuki yet, as I haven't felt it was needed.

I put Seafoam in all Jerry cans and give the vehicles a can every second or third fill up. Very happy with the product.
