talkin about this 'heat ', i just got my old ac 300 back from my cousin. before i sold it to him it needed new rings. so i put a new piston and rings in along with boring it out. anyways, the three years that he had it he never rode it(thats why i have it now) but he put 'heat' and stablizer in it. my buddy and i went to pick it up and the battery was dead, pulled it two times and it fired right up. when taking it apart to put a new timing chain in, we had to pull the carb. it was full of thick, gunky crap. i looked in the gas tank and it also was full of black, gunky crap. (almost like he dumped two quarts of 2 stroke oil in it .) to get to my point i would have to say that bear 4570 would be right. it ate away the metal that the flaot in the gas tank slides on.(gas guage) . now we have to clean the whole fuel system or replace it. after seeing that i relized im never puting heat in my ac500 gas tank. then again ive never had problems with starting in the cold. 10 degrees today and it fired up!! ya'll have a good weekend.

 

What do you think of using Marvel mystery oil in gas tank? I have heard it is very good for cleaning the fuel system and can keep the H2O levels down like good dry gas.

 

That was my point, many people put the yellow bottle of HEET in, I said it was alright to use with ATV, but as Bear pointed out maybe not the best, but when I had a frozen fuel line in my truck it sure did the trick. However, the RED one is new, and it the way to go now. It is even safe for 2-strokes.

 

I honestly don't use either. I go to wal-mart and by the rubbing alcohol that is 90% isopropyl and have used it in cars and trucks for many years with no problems. I don't know what the other 10% contains, But the iso- heat isn't all alcohol either.

 

Huh? First - I would prefer to not use any alcohol in my fuel but there is little choice. But, I can't find anything that supports ethanol being a "bad" alcohol. There is plenty written regarding damage caused by methanol.

We have 10% mandated ethanol already in the gas - (don't all northern states?) we really don't need to add Heat or anything else.

Gas line anti-freezes are made from ethanol, methanol or isopropyl alcohol to absorb water in the fuel and keep it from freezing. That one little bottle of gas line anti-freeze is about 0.3% of the volume of a full gas tank. With a 10% ethanol blended fuel, it's 10% so it will absorb a lot more water and you'll never have to worry about a frozen fuel line.

You can use the 10% ethanol blended fuels anywhere you use regular unleaded fuel. It can be used in any lawn mower, snow plow, snowmobile, ATV and any other gas powered engine. There may be some carburetor adjustment needed

Unlike Methanol, Ethanol is a very safe fuel, if you spill it it will not contaminate the ground water. If you drink it, you'll get drunk. Although if you drink large quantities you will suffer liver damage. In fact, if you drink just about any alcoholic beverage, you're drinking ethanol in one form or another.

Water is soluble in ethanol, otherwise you would have to shake your beer to mix the alcohol with the water, and we know what a mess that makes.

 

Good point WhoDat, when I lived in MN I ran nothing but Ethanol and put over 200,000 on two different cars. Up here in AK all we have is the cheap stuff...

 

Please reread the following again. "Second the bad alcohols will only hold a certain amount of water and if there is more water that they can hold, the 3 fluids seperate out into layers. Bottom layer is water (where is your fuel pick up, on the bottom); then the alcohol and then the gas. Bet your engine doesn't run well on water or alcohol. Isopropyl also hold water but any water it can not absorb it just ignores and keeps itself and and the water it is holding in solution with the gas. You end up with a very small amount of water in your tanks sump. Also Isopropyl is not corrosive. Never use any product with the bad alcohol and unless Heet has changed it uses the bad stuff."

"Ok, I just checked and Heet now has "Iso-HEET" which has isopropyl in it and comes in a red bottle. The Yellow one appears to has Methyl in it. So Catterman is wrong, use the red bottle in all cases, the yellow is bad. "

Also ethanol is corrosive to you hoses and metal parts of your fuel system. I have seen what it does in carbs and hoses. All the marine manufactures will not sell anything but isopropyl. All alcohol wiill hold water, the stuff in your medicene chest is isopropyl mixed with 30% water. The use of ethanol in gas is because it's cheap, not because good. If you thik drinking it good for you, you need to do some research on the latest infomation.

 

Anyone have info on the Mystery oil? also I see a post stating they using rubbing alcohol in thier tanks? Is that ok for the system? Sounds like a good cheap alternative to the $3 + cleaners and anti freeze products I am using now.[img]i/expressions/face-icon-small-confused.gif[/img]

 

I heard about the Myestry oil deal many years ago, but nothing recently as there are really good products out there now. Thw trouble with rubbing alcohol is it is leady 30% water bfore you put it in your tank, I think not a good idea. All rubbing alcohol is is isopropyl alcohol with water added as a thinner. Using the automotive or marine isopropyl alcohol produces would be a wiser way to go. The automotive products are cheaper, NAPA used to have an isoproyl product that was labeled 99.99% isopropyl alcohol. I haven't looked to see if the still have it, but it worked super. I bought it by the case for the 3 boats I had at the time.
