The gas that I've been using in my boat is made with 10% ethenal. Can I use the regular Stabil or should I start using the new one that is made for ethenal?

I've been using the older red Stabil for years and we've had ethanol in Michigan gas much of that time. I am happy with the results. I may switch to the green stuff if I can find it- no luck so far. Either Stabil product is better than nothing.

The new Stabil Marine Formula supposed to work and protect better against ethanol related problems, I just bought a bottle last week, its twice the price but you only have to use half the amount compare to the regular stabil.
