2 cycle oil

I think corn should be kept on the cob, served with butter and salt

Agreed. Yummy!!

Another problem with ethanol is the storage of engines using it. The owners' manual for my 4 stroke Yamaha sno-mobile advises completely draining the fuel system if (gasohol) is used to prevent corrosion damage to internal engine components, including the fuel system, cylinder walls, crankshaft and apparently every other component made of a ferrous metal, due to ethanols' ability to (attract) water.The manual specifically states treating the fuel with a fuel stabilizer is not sufficient!

Didn't mean to hi-jack the oil thread, just some info related to the topic

I know a mechanic who says that Startron and/or E-Zorb is formulated to be used as a gas stabilizer for alcoholic gas. Startron is avail in the boating/sports section of WallyWorld. EZ, I'm not sure. Maybe a marine store. I think both products were initially sold to solve fuel releated probs in boats.

I'm going on my 3rd season of running a 4 stroke trimmer/brush cutter and it's done such a great job I've added an edger and pole saw attachment to it. I do not miss the 2 stroker nor the mixing of oil in the fuel. Just make sure the crankcase is full of 30w (which so far it hasnt used any), add gas and go.

My chain saw is a 2 stroke and the last oil I bought for it was syn, thats all they had so I figured what the hay. I don't work the chain saw much but it's done great when I have.

Some WalMarts also carry the new Marine Stabil ( and its a nifty blue color ) intended to combat storage problems with ethanol laden gasoline...I've been using it for a few months. It, of course, costs a lot more than the regular red Stabil.

Skyco; The marine sta-bil apparently slows the ethanol (VOC) evaportion, keeping the fuel fresher over time, but does it do anything about ethanols' inherent ability to "attract" water. This seems to be the area of concern of engine manufacturers.This is not yet a problem in this part of the country, as just a few outlets are offering a 10% blend, but I'm sure it will be in the not-to-distant future

The only way that I know that you would have a water or moisture problem in an engine using ethanol is. That it tends to run cooler in the engine which causes condensation within the engine. I'am not aware of or if the 10% that in the gasoline mix would cause these condensate problems. When I had a drag car . I ran 100% ethanol. Which produced a vast amount of moisture in the engine.The oil in the motor was so milky & watered down ( after only 1 pass )that, I had to change the oil often .I have checked the fuel mpg in my personal vehicle with the 10% mix & with out . I get better mpg with out. My atv's even seem to run better with out 10% ethanol. That being said. It's getting harder to find gasoline around here without 10% mix. There are a couple Exxon & BP stations that have gone to 10% ethanol mix

From the Marine Formula Stabil website-


How does MARINE Formula STA-BILï½® Ethanol Treatment and Performance Improver work, and how is it different from Regular STA-BIL?
MARINE Formula STA-BIL Ethanol Treatment is a new, enhanced formula of STA-BIL, America's top selling fuel stabilizer, that was designed to fight many of the unique problems related to ethanol in gasoline in the moisture-laden marine environment, and fights those problems in three ways:





Fights Fuel System Deposits Ethanol in gasoline acts as a solvent on the accumulated deposits in marine fuel tanks, fuel lines, carburetors, injectors. These loosened deposits can cause engine performance problems, including hard starting, rough running and stalling. MARINE Formula STA-BIL cleans-up power-robbing deposits from carburetors, fuel injectors and intake valves to improve engine performance. MARINE Formula STA-BIL contains more than FOUR TIMES the fuel system cleaner in Regular STA-BIL it is a Complete Fuel System Cleaner.

Fights Fuel System Corrosion Ethanol in gasoline attracts water from the moist marine air. Since virtually all marine fuel systems manufactured through 2007 vent to the air, the ethanol continually attracts water which can cause corrosion damage to marine fuel tanks, fuel lines, carburetors and injectors. MARINE Formula STA-BIL contains DOUBLE the corrosion preventer in Regular STA-BIL, to fight the unique problems of ethanol in gasoline in the marine environment, including marine fuel tanks which vent to the marine air.

Fights Fuel Degradation Pumped gasoline starts to degrade immediately. MARINE Formula STA-BIL keeps fuel fresh for up to 12 months in marine gas tanks. Just like Regular STA-BIL, adding MARINE Formula STA-BIL Keeps Fuel Fresh , and eliminates the need to drain fuel prior to storage.


So it appears it works by protecting from corrosion caused by the water picked up from the atmosphere by ethanol laden gas.....it apparently doesn't do anything to prevent the gas picking up the water in the first place.*
Sure wish I could find somewhere to get gasoline without the ethanol in it for my power equipment and toys. I find many stations that lack the required posting, its the law here in SC they be posted on the pump if they have ethanol and how much, but I suspect rather than actually not having ethanol, they are just in violation of the law....sort of like the one near me that has a low price out by the road for kerosine but the pump is $.20 higher....told them about it twice now and they still haven't changed the sign, for over a month, again a violation of state law.

*used to run Redline Racing 2 stroke synthetic oil in one of my dirt bikes...kept finding a water bottom in the tank and petcock filter sump. Finally determined the oil was hygroscopic removing moisture from the air. Switched back to Yamalube, a petroleum based oil, and never found water again....

In,NH some of the stations way up north didn't have to have ethanol in their gas. We run Polaris,Skidoo and Yamaha sleds. We try to buy our gas up north. Gasoline in southern counties had to get it depending on how each counties emissions results were. Rubber fuel line,carbs. can have problems in sleds from the ethanol. Even emissions for vehicles at inspections are harder in southern NH, mostly Rockingham County. Northern NH is less populated. plowking

Last bottle of 2 cycle oil I read said something about the ethanol /gas mix absorbing more water, etc.. and that was causeing the mix problem.. etc.

Well, I just had a look at one of my Stihl 2-cycle oil bottles (little 2.6 oz. bottles for one gallon mix) and it says fully synthetic, biodegradable, contains a fuel stabilizer, to use 89 octane gas, but no mention of ethanol or water.
