Additive gas is a personal choice, but, I put 1-2 ounces of Marvel Mystery Oil per 50 gallons of fuel in our boats.
It has proven to be a good racer's tip. It lubes the top end/cylinders and brings the combustion temps down a tad.
The Ethanol has a tendency to wash the lube oils away.
My other secret weapon is SeaFoam. Great stuff, especially for 2-stroke outboards that don't see a lot of high RPM use. It is a stabilizer and it helps clean carbs/passages and cylinder carbon build up.
The new Stabil for marine use is de-rigeur for winter storage.
