Found out there is 2 different kinds, at least, that is what I have seen in the stores. Bought the Stabil 360 the other day, and put it in the lawn tractor this Afternoon. Ran the tractor for about 10 minutes. One bottle was supposed to treat 20 gallons of gas. 2 gallon tank on the tractor . 4 Gallons in the gas can. I put half the bottle in the gas tank on the tractor and the other half went in the gas can. Ran the tractor for 10 minutes , then put it back in the shed till Spring.

Is the 360 as good as the regular Stabil ? I was able to buy enthanol free Gas . Hard to find around here.

I think the 360 is advertised as keeping the gas fresh for 12 months. I don't know how long the regular Stabil is supposed to keep gas fresh, but I have great success using the regular Stabil for 10 months of storage.

I've used both and prefer the 360 when I can find it. Every engine at the fishing lodge gets it before being put away for the season, and the jet drives get it in every tank.

Use the regular on my tiller, lawn mower, tractor and motorcycle...
Never have an issue in the spring when we put out the garden - good stuff.

I use either up here.
I think it's more important to use non oxygenated fuel which you have. You will be fine.

The marine and atv shops in this area use seafoam so that's what I use

If you got ethanol free gas, you do not need to put Stabil of any sort in it. Its the ethanol that causes the problem that Stabil is made to cure.

The 360 is for ethanol treated gas,

I have used sea foam in the atv's at my place and have not liked the results. My carbs get a gummy build up. Not sure why, so I use
Stabil in all small engines, atv's, snowgos, mowers, chainsaws, boats, generators, and all else.

I'll disagree with you a bit. While I'm a great advocate for ethanol free gas (I use it in all my small engines), pure gas will still produce varnishing problems when stored for long periods of time. I believe that Stabil has been around a lot longer than ethanol gas.

Omc makes a product called 2+4 for boat engines or any other, works better then all the rest I have tried.

I agree with you about that. I never use anything but ethanol-free gas in my ATV, snow blower, snowmobile, etc. I didn't put any additives in my snow blower last spring. It wouldn't start this winter. The carb was all gummed up. I will be either running the carb dry this spring or putting it away with Stabil.

Been helping out on and off for a local guy who does marine and small engine works. He has been using a product called Startron for a few years and have to admit that after using it myself won't go back to anything else. If I recall correctly, one large bottle 10-12 oz does something like 300 gallons. Good for both ethanol or non-ethanol gas.

If I use anything it is STARTRON it is a enzyme and works very well for a long time.

I use hi test gas in all my small engines, and treat it with startron. Use to use stabil and had a problem, went to startron and no more problems.

I use non-oxygenated gas in all my small engines, ATV , outboard, snowblower, chain saw etc. Non ethonol gas is different. The non-oxygenated is sold in Mn only for use in non highway engines. I don't add anything to the gas tank from season to season and have NEVER had any carb or fuel injector issues. My boat gas has sat for 18 months once and fired right up and ran great. My snowblower is about 10 years old and runs great with whatever gas is in it from previous season. I am very particular about not storing gas outside in the rain.

I think higher octane burns slower by design to prevent spark knock. I get better starting using 89 octane than the premium. But the 89 octane is rec gas with no alcohol at all, and I still use startron as I never know how long something will sit.

non-oxygenated gas is 91 octane

The rec gas I buy is certified as 89 octane, straight gas no ethenol.

The short answer is that octane is the measure of how much compression a fuel can withstand before igniting. Meaning in what position the piston will be when the fuel ignites.If it's to far forward or backward top dead center you will get a knock.

This is why you always use the recommended octane rating from your vehicles manufacturer. Anything else will not be good for your engine or get you better gas mileage as some believe.

Another reason to stay away from high performance engines that require high octane fuel that cost more because less is produced. It's not that the fuel is any better just that it fires at a different compression.

PS never use an octane booster if you put in the right octane in the first place.
