Around here the problem with boats and ethanol blended fuels is the condensation caused in the gas tank by ethanol. I run marine fuel with no ethanol when it's available. Otherwise I count on an inline filtration system with a moisture separator. I'm running a high tech 2 cycle Evinrude using their high performance 2 cycle oil. I'm not aware of a fuel additive than can compensate for the water condensation in the tank. I'll check out their marine formula.

After having some problems with my weed-wacker and lawn mower a few years ago, I started using uncontaminated gas plus Sta-Bil in all of my small engines. I even feed it to our cars on trips to Paducky and it improves our fuel mileage about 10-15%.

Find a station near you: http://pure-gas.org/ Prices in Georgia and Tennessee run about 10% over ethanol. Stations in Kentucky are nuckin' futs. They want about $1.00 above ethanol. Your power equipment stores will sell you "small engine gas" for about $8.00 a quart.

 

^You can also use 100LL Aviation fuel. It, too, runs at least $1.00 per gallon more, but there are no moisture problems with it. Find a small airport near you and they will more than likely sell you 5 gallons.

Several of my friends use AvGas in their power equipment.

 

Red Sta-bil with regular (no ethanol)gas. never a problem starting even after 6 months.
Just emptied about seven (7) gallons of 'snowblower' gas with Sta-bil into the van. Glad the snowblower wasn't needed as much as a couple of years ago.

 

I always use Sta-bil red. I put it into the gas cans that I fill for my generator, snow blower, garden tractor and etc. I always use it and never had a problem.

 

The last time I took my Kawasaki out of the garage and rode it, I drained the gas, put fresh gas in it and then added Sta-bil. I have yet to see if it starts up. This thread makes me want to go to the effort to get it out. The NSX has to come out first and it needs a wash after today's drive to Big Bear for a meet.

 

I have never had any trouble starting the Jeep in CO after two or three months storage, but I use Sta-bil in the tank for good measure. For the mower, chain saw, and weed eater, etc. I just dump the old gas and siphon in some new. Sometimes that gas is more than a year old.

 

I too have used Stabil in my gas powered utility vehicles (Wheel Horse garden tractor, weed whacker, etc) over the years and have not experienced any problems with it. However recently a long time friend turned me on to Star Tron which was recommended by his mechanic and I found it at my local Toro dealer as well. I have to admit that I have not tried it yet as I still have not exhausted my supply of Stabil.

It seems that it is designed to work with Ethanol blended gasolines most of all brands contain about 10% Ethanol.

 

I have an emergency generator that has had gas in its tank (with Sta-Bil) for over 7 years. Each year, when I test it out before hurricane season, it starts on the first pull. Maybe I should drain the tank and refill it? Nah! I think not.

 

At the start of the mowing season my mower deck on my 1977 Wheel Horse tractor was inoperable due to the failure of the factory sealed bearing assemblies on the mower deck blade spindles that finally gave up and seized. So, for the first mow of the season I had to rely on our 1987 Honda HR-21 self propelled mower. When ever I use it I always turn off the fuel petcock and run it until it runs out of gas in the float bowl. I had Stabil in the gas in the tank and after two years it started on the first pull.
