So while so of the gas pumps on the lake do add in a stabilizer additive there is no guarantee as to how well that additive is distributed in a bulk application. Hence it always wise to add some of your own. Most of the common additive do publish that over concentration is not a problem. Not that I would recommend drastically over doing it. Now as for me I have used primarily Star-tron and had tremendous luck with it for the last 3 seasons. This year I start with Sta-bil marine formula, and am actually not as impressed with it. I believe then engine is running a bit rougher. But having said that it may all be in my head. At any rate I will be going back to Star Tron, as it has proven itself to me over time, and you might as well use what you know.

Another not here, is that if you keep stabilizer in the gas, it is also best to keep the tank as full as possible when the boat is not in use.... less chance for moisture to invade.
