Tommcat Posted February 22 Share Posted February 22 there is no downside to running with ethanol fuel, you just dont want to store anything with it. ALL fuel here is mass is 10%eth by law, so i guess i'm just used to it 1 Quote Link to comment Share on other sites More sharing options...

ALL fuel here is mass is 10%eth by law, so i guess i'm just used to it That's been our way of dealing with it ... if we HAVE to put in ethanol fuel we want to make sure we burn through it and don't store the sled any longer than necessary with it in the tank. Fortunately for us around here, 91-non ethanol is pretty common and what we use in all of our off road stuff, including mowers, chainsaws, etc. 1 Quote Link to comment Share on other sites More sharing options...

The point where you get into trouble with ethanol fuel is old or extended storage periods. I can see issues with guys storing their sleds with ethanol and not pumping it out and putting fresh fuel in. Even treated fuel with a stabilizer I wouldn't trust.

And people seem to think it's always fresh when they pump it at the station. Even keeping sleds outside overnight you can get condensation in a tank. It's just not great to use and it's heavily subsidized for dumb political/$$$ reasons. I'd rather pay the farmers to grow food instead of shitty ass fuel. We have plenty of oil 3 Quote Link to comment Share on other sites More sharing options...

ALL fuel here is mass is 10%eth by law, so i guess i'm just used to it buddy of mine has two N/A drag cars and a bike than run exclusively on eth, and make great power but were built for it from the start. each get completely drained and cleaned top to bottom of it between races. storage is the issue regarding separation. for those following along that want to do a test... take a glass jar, put E85 in it with a lid, set it on a shelf for six months and watch the 'water'/fuel literally separate. there's powa in the corn squeezins for a limited amount of time. if not for subsidies, you wouldn't likely see ethanol based fuels. but that's an entirely different discussion. https://www.google.com/finance/quote/ZCW00:CBOT?hl=en&window=MAX click max on the chart...

Tommcat Posted February 23 Share Posted February 23 one other thing i'll throw out there for the guys that may be just starting to see ethanol in their area, and we learned here the hard way, it is a great cleaner. and the downside to that, is that tanks and lines that have never had it before will get all those years of crap cleaned off the inside when they initially start to switch over to it. and that sludge goes right through the pumps to your car, truck, sled or whatever. after switching over, stations were seeing massive amounts of sleds go down shortly after fueling up. and, it will also clean out the entire inner lining of any older fuel line produced before ethanol fuel existed, putting a nice pile of black goo in your pump, filter, injectors etc 1 Quote Link to comment Share on other sites More sharing options...

It will pull moisture from the air. Once the water concentration is high enough the water and ethanol combine and fall to the bottom, creating a mix of corrosive shit, and super low octane fuel floating above it. I've seen it eat through the bottom of a 2bbl marine carb, to the point that fuel was just running onto the intake. It also destroys fiberglass fuel tanks in boats, and aircraft Edited February 23 by krom Quote Link to comment Share on other sites More sharing options...
