aviation gas in a snowmobile? problems?

i found a local pilot that lets me through the gates but im going to do a security test at my local airport so i can acess it when ever i want. You can pay at the pump with a credit card at out airport. And they say they want the business so if i show up with 55 gallon drum all the better.

Av Gas

Generally most small town airport dealers will love to see you comming. Perferable if you perchase more than 10G.
One other problem is lots of people are saying "I ran 100LL for years with no problem" running it for years is great, the reality is we need to know how many miles are on that motor. Some people do 1500 miles per year and others do 400!

what is the average price of av gas compared to race fuel. If anybody knows what it is in Belgade MT that would help to.

I bought 45 gallons of 100LL AV gas yesterday to burn in my T-Nytro and I paid $1.64 a liter Canadian. A while back it was $2.05 per liter.

I called the place at the local airport, there just a service company and have hangers, they said just walk into there office and talk to somebody and thell let you out to fill your approved tanks.

avgas

i've been using 100ll for years , it has a higher flash point that regular gas and burns cooler. the problem is because of that it burns white , so your exhaust pipe is white and your pistons are white , u cannot tell piston wash accurately when using avgas, which hinders your capability to tune properly

i paid 1.50$ last week at our airport

The name "octane" comes from the following fact: When you take crude oil and "crack" it in a refinery, you end up getting hydrocarbon chains of different lengths. These different chain lengths can then be separated from each other and blended to form different fuels. For example, you may have heard of methane, propane and butane. All three of them are hydrocarbons. Methane has just a single carbon atom. Propane has three carbon atoms chained together. Butane has four carbon atoms chained together. Pentane has five, hexane has six, heptane has seven and octane has eight carbons chained together.

It turns out that heptane handles compression very poorly. Compress it just a little and it ignites spontaneously. Octane handles compression very well -- you can compress it a lot and nothing happens. Eighty-seven-octane gasoline is gasoline that contains 87-percent octane and 13-percent heptane (or some other combination of fuels that has the same performance of the 87/13 combination of octane/heptane). It spontaneously ignites at a given compression level, and can only be used in engines that do not exceed that compression ratio.

During WWI, it was discovered that you can add a chemical called tetraethyl lead (TEL) to gasoline and significantly improve its octane rating above the octane/heptane combination. Cheaper grades of gasoline could be made usable by adding TEL. This led to the widespread use of "ethyl" or "leaded" gasoline. Unfortunately, the side effects of adding lead to gasoline are:

Lead clogs a catalytic converter and renders it inoperable within minutes.
The Earth became covered in a thin layer of lead, and lead is toxic to many living things (including humans).
When lead was banned, gasoline got more expensive because refineries could not boost the octane ratings of cheaper grades any more. Airplanes are still allowed to use leaded gasoline (known as AvGas), and octane ratings of 100 or more are commonly used in super-high-performance piston airplane engines. In the case of AvGas, 100 is the gasoline's performance rating, not the percentage of actual octane in the gas. The addition of TEL boosts the compression level of the gasoline -- it doesn't add more octane.

I keep a drum in my trailer and fill it about half and half with 91


I run alittle in everything.....makes mowing the lawn alot funner

I have not read the other posts.

I have ran a minimum of 2 gal. of AV to 10 gal of Premimum forever. I have an 01 Polaris 800 and I had 7000 miles on it and was still getting 74 hp at the track at 4000 ft. Without the AV, I occassionally get a slight detonation at lower elevation. I chose to do the crank and bearing update at 7000 miles, the engine has yet to fail. Polaris 800 cranks have a bad rep; they like to fail around 1200 -2200 miles. I have at least another 3000 miles on my rebuild now too.

I seriously need to get an account at the airport.

Amen, Brotha! I have an old Lawn Boy 2 stroke....leftover AV gas and synthetic sled oil in 'er and I just dream away when I'm cutting the grass!

Works great in the weedeater too.

Nice to know I am not the only one running AV and 2-stroke oil, and I am not the only one that enjoys the hell out of it.
