Sta-bil Marine Formula Ethanol Treatment
 

Has anybody used this product? And if so, do you have any feedback on it?

The consensus I read on it was to save your money and buy STAR TRON enzyme treatment instead. Also run the engine out of fuel if at all possible.

I've been using Startron since they started shoving E10 down our throats and I haven't had any gas problems, so I'm sticking with it.

Also, I used to keep my tank full all the time and over winter. The prevailing wisdom was to prevent condensation in the tank.

After researching EXPERT? opinions on Ethanol problems...OLD gas = BAD

Now I let it get down to 1/3 tank or so before filling and run it low for winter lay over.

The idea being NOT to add a little fresh gas to lots of old gas, but to add more fresh gas to a little old gas.

PS. put some in that "lawnmower" gas can in your shed. And the "Oil Mix" gas can for the chainsaw....

I have used it for the last couple years in my 4.3 litre V6 I/O and so far, so good. Recommended shot of it with a full tank in the winter followed by another shot in the spring. It seems, however, that the I/O's are a little more tolerant of ethanol than are the outboards.

I use Marine Sta-bil but I also use Sea Foam along with it. When I put boat away for the winter I completely fill both tanks and treat heavy with Sta-Bil & Sea Foam. Each springtime I have never had one single issue starting up, and the 175 Johnson runs great. Maybe it's just me having such great luck? I do know this, I will not change my routine seeing as it works great for me. Had the carbs rebuilt when I first bought the boat and they have been fine and clean since, with no issues whatsoever. During the season I use the normal dose required by Sta-Bil and Sea Foam makers with never an issue.

I've used Sta-bil and Startron with good results

nothing in a can or bottle will replace proper maintance and a good mechanic

No, but they can help prevent it if you use them properly. It sure keeps me busy now with ethanol at the pumps. unfortunately ethanol cost me a bundle this week with aggrevation from my chainsaws.

Give the BRP Johnson/Evinrude 2+2 fuel stabilizer----A try--you will be pleasently pleased with your purchase---I have tried just about everything with this crap fuel---and I have been happiest with this product--it ran like I had fresh fuel in it--not 6 month old fuel or like half dead fuel like Sta-bil or seafoam or even ---startron--which was second best.

What is the 2+2 formula? Is it a carb and cylinder cleaner or a fuel conditioner/stabilizer formula.
