Warning from Poulan regarding alcohol in fuel

Recommended Posts

The issue of alcohol in our fuel has been discussed here many times. I recently bought a Poulan chain saw and in the instruction manual was the following statement about fuels containing alcohol:

?IMPORTANT

Experience indicates that alcohol-blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system should be emptied before storage for 30 days or longer. Drain the gas tank, start the engine and let it run until the fuel lines and carburetor are empty.?

Thought you would find this interesting.

Steve, that is an interesting statement, but the main part of that message is "storage" and as all of us "old antiquers" know, you should never leave old fuel in a fuel tank for a long length of time, whether it's regular gasoline or gasohol.

Last month my wife had me get an old used roto-tiller out to work her flower garden. Got it running, but only by passing fuel directly into the 'carb. Finally located the problem, a completely stopped up fuel tank (crud). As you said, it's a good idea to drain all old fuel out of tanks. <img src="http://forums.aaca.org/images/graemlins/smile.gif" alt="" />

The issues of storing and using old gas are well known, what I believe is significant here is that they say to get rid of it after 30 days.

Gasoline issues can be REGIONAL. I know of many Indian owners in other parts of the country with problems of gas eating up reproduction 'plastic' and factory cork floats. I've had no problems here in Tn.

Yes, alcohol absorbs water. Most so-called 'de-icers' and fuel line cleaner additives have alcohol. If i understand correctly, it is alcohol that will dissolve NEOPRENE which is used in most fuel delivery systems. THe two stroke small engines usualy have neoprene diaphragms.

AS for 'old gas' syndrome i have just proven it wrong way too many times at least in terms of gas here in Tn. I've started engines in everything from 89 Caprice to, 48 Indian, 56 Cushman, tractor, and at least 20-50 other small engine powered equipment i have around here. All of these at one time or another has sat for as long as 2 years. I think the Cushman sat one time for about 3 years without running and it cranked right up and ran fine once i FINALLY found a coil for it.

I've seen the very sticky gooy gunk in many a small engine tank, m/c's and other applications of UNKNOWN ORIGIN. One tank was so bad that when some of the goo got on the garage floor it stained it for GOOD. BUT THESE were of unkown origin and i am guessing the goo was due to fuel additives added by the owner. NEVER USEA FUEL ADDITIVE!!!!! NO STABILIZERS!!!!

it seem like this year almost every thing that sat with gas in it gave me a lot of problems starting and running.[except the old harley which starts no matter how long it sits].makes me wonder what is different this year with the gas.the desoto i run every month and add fresh gas over the winter and that i have no trouble with so far.

Hit the carb with a little starting fluid. OR , remove 2 or 3 sparking plugs and squirt about a teaspoon full of oil into the cylinders and try it again.
