Yesterday, somebody told me that running isopropyl alcohol like ISO HEET or HEET in a snowmobile to absorb water is bad for the engine. I'm a little hesitant to use it now. Anybody know if this is true???

I don't know, but I've never had any problems.If you don't want to use isopropyl, then get one of those moisture absorbing cylinders you drop into the tank.Either way, you have to do something to keep water out of the fuel system.

You refer to like dry/gas. It may be dammageing if you are not carefull the intended amount of isopropyl is aproximate (9-12oz. for 30-40 galons). You're sled does not hold that much fuel.
If you have a high performance engine be even more carefull isopropyl will change the burn rate of the fuel.

Lots of people are full of mis-leading information.

First of all Isopropyl doesn't hurt anything, but methol-hydrate does. if you are gonna use something to take water out of fuel, use Isopropyl, not methol-hydrate.

polaris recommends that regular use of "their" de-icer at a rate of 1-2 oz. per gallon of gas, also alcohol blended gas should only be used at a rate of 10% or less, using more than 10% will cause the engine to run leaner which will result in engine failure. however i have never seen conventional gasoline at a rate of more than 10% (ethanol) which is at 10% or less. i have used de-icers, and have never had a problem, but remember, most of us only have around an 11 gallon tank or less, so you should be careful in the amount that you dump in the tank. a good rule is to never leave you sled over night or for long periods of non-use with less than 1/2 tank of gas.

Wouldn't the isopropyl alky, break down the oil mixture that is lubin' everything up? I think I would be a little afraid to use it. My luck I would burn up an engine. Scott

If you know absoultely nothing about it, dont take the chance. In some cases, storing sleds with that crap in the cylinders can cause corrosion in long term use, so if you dont know, dont try it.

Its not gonna hurt anything to run iso. polaris tells you straight up in the owners manual to use it. it says if you are using non-oxygenated gas to use iso definatly and if you are running oxygenated gas they say not to use it. in MN non-oxygenated is the 92 octane and the other is 89.

this is true, i wouldnt store my sled with de-icer in it, after a season of ridin, and youre gettin ready to put it away, if you have de-icer in, drain the tank, and refil with fresh gas, run your sled for awhile to get the fresh into the lines/carbs, etc, then put some sta-bil or some sort of other kind of fuel stabilizer in it. and fog those cylinders!

I know this has probably been beat to death, but....Straight isopropyl will hurt nothing if used sparingly. Everything I have read and the people I have talked to swear it is fine if used in small quanities. Small quantities because sled tanks are small. One capful to one tank of gas is what the general consensus is.

thats good advice, i have also read that de icer wont totally rid your fuel system of all the water, just reduces the amount

I've never had an icing problem, even with my 14 year old Cat. I've had it sit outside all night at -15 to -20 and on the second pull it starts.
Run top grade premium fuel and ride alot, I would'nt think you'd have a problem with water or moisture building up in the tank.
Just my opinion.
