100 octane low lead av gas

Well, then i have to ask, Why not a synthetic like Klotz or Amsoil?

First, it takes longer to break in new rings. Second. sled doesn't run as well. On my dyno, cheap oil mixed thick makes the most power. I am sure someone else will disagree. That is what I find. Most of the teams I run with do not run synthetic oil. Some do , most do not.

octane is all about improved combustion efficiency,you can lose power in a engine if it has to much octane but you can not over octane an engine, to high of a octane it will just run out of the exhaust unburned under high r.p.m. so what you want is more of the gas being burned in the combustion chamber making more power, the same for race gas experiment

First, DO NOT keep Ethanol gas in your snowmobile for the summer, drain it out and put NON Ethanol fuel in it. Fuel and Gas additives, most are snake oils and will not last more then 90 days,
Take a jar and put 3/4 of the gas you are using in it, take one OZ of Sta-Bil, this will over dose it, then fill the rest with water and shake well Let it sit for a few hrs, if it does not work and seperates it will look like a lava lamp in action. If it does work it will stay same color.

Ethanol = Moisture magnet. Ethanol = Highly oxygenated fuel = leaner air/fuel mixture.
Take a look at two comparable (displacement etc) competition engines. The one that uses "gasoline" is running a lot less (raw) fuel through it than an engine that burns straight methanol. That is a extreme comparison, however.
In the case of older snowmobile engines: They were engineered and thier fuel curves/calibration set up and tested to run gasoline NOT "gasohol" or gasoline/ethanol mix (which has a higher oxygen content than gasoline).
I worked as a small engine/marine mechanic back in the early 80's when gasoline was gasoline. Yes, we found shellac in carburetor bowls of poorly maintained units. Nowdays, talking to friends still active daily in the trade, they are finding a jelly-like substance left behind from gasoline/ethanol and corrosion and degredation of components like o-rings etc. A friend who works at a Toro dealer tells me there is updates and service bulletins constantly coming through for fuel systems because of the effects of ethanol.....

I agree. Reformulated gasoline (RFG) arrived via government dictate and was billed as a cleaner and allegedly renewable fuel to save the planet from the evil of capitalism. The cleaner and greener component was the oxygenate, which, after political fistfights and money changing ended up as ethanol. The aforementioned ethanol, mixed with gasoline at taxpayer expense, resulted in the fuel being "oxygenated" or "thinned" but at a price per gallon comparable to straight gasoline yet providing less energy per gallon. The beauty of all this from a political vantage point was the subsidized fuel cost about the same, but since more was needed to accomplish the mission involved, increased tax revenue arrived via excise and motor fuel taxes. Meanwhile, older engines of all variety suffer all manner of evil because they cannot compensate for the net energy deficit per unit of volume because the fuel mixture is not governed by a computer.

Guys. Ethanol based fuel is here to stay. I remember the same kind of " the sky is falling" stuff when they phased out premium leaded. Don''t let the fuel sit untreated for a year in a carb, jet up a size or two and run premium when possible. The stuff works fine. We occasionally compete at races where we have to run a spec race fuel different that our normal fuel. We don't pack up and go home, we compensate for difference in the fuels. Sometimes we even run better. Peter

Ethanol is subsidized with confiscated tax dollars and would otherwise not exist in it's current form. I am not convinced the subsidy scheme is forever because eventually the taxpayer grows tired of unnecessarily trumping the laws of physics with limited supplies of wealth.

That, I do agree with. But it will be with us a while. Peter

I really don’t know how we got to the political end of this post, nor do I care to indulge that part, other than to say:

The concept of subsidies for alternative fuels is sound. Without it no really new breakthroughs will occur!

Hopefully someone or some company will come up with a alternative fuel source or power source and not have them be gobbled up by one owner like Archer Daniels Midland has done!......but then ………..well you know!

Now back to the original post:…………or high jacked topic in this post:
Ethanol was the first fuel used in a internal combustion engines.
Chemists knew it would produce the most amount of power, and was the most readily available.
The theory being farmers could use agricultural byproducts to produce fuel for these engines.
Otherwise they my well have run on whale oil, much to the whales dismay I’m sure!!

Truth is with the huge reserves of crude oil found in the United States and taxation of distilled alcohol. Gasoline became next logical fuel.
The reason is because .....of a barrel of crude oil about half could be produced into gasoline with fuel oil, and virtually all the other byproducts used for modern day life.

That’s why Henry Fords first cars had A variable carburetor to run on either fuel.

Because modern refining methods are so efficient and the by products so useful I don’t see gasoline being totally phased out for some time to come.
But I do see other products added to try and find a happy medium between green energy and cheap energy.

Once again are job will be to educate ourselves to use newer fuels that are readily available on the trails in our older machines without damaging them.

OK I'm done!

Surely you dont really believe that do you?..................Government beaurocracy is what is keeping development at bay. The idea of picking winners and losers by Government subsidies is obsurd but that is what is happening everyplace and hinders inovation. Creating an un-equal playing field is what has seperated all of us.

Facts are stubborn things.

It's a fact ethanol takes on water, which makes it useful as a gas line anti - freeze but it still dilutes the fuel from it's original mission. It's also a fact that ethanol requires more energy to create than it generates after creation, hence the requirement of tax dollars used to overwhelm physics. It just isn't sound policy in the current iteration and will never be until private enterprise actually creates a market disciplined replacement. Subsidies promote laziness by degree and then, as Chuck aptly pointed out, government is empowered to pick the winner which is the essence of crony capitalism. Remember the original fight over oxy gas was ethanol vs. methanol; ethanol was chosen by virtue of a stronger army of cronies in league with the federal government. I personally am unable to locate the sound concepts behind the poorly named alternative energy when all of it is cloaked in taxpayer funding controlled by elitist masterminds, most of whom are driven around in taxpayer funded limosines. The reason straight gasoline still dominates is because it contains more energy per pound than ethanol and is less expensive to refine despite the best efforts of government to hamstring it's production. The needless and confusing patchwork of regionally mandated summer blends of gasoline are alone enough to strangle the entrepreneurial spirit out of any sane individual.

Those of you who claim not to care about politics would do well to remember that our Founding Documents were wholeheartedly political in nature and substance.
