Aviation fuel?

[BigGreenMachine]

A while back I turned down an offer from CT Racing to shave the head of my Tecate to raise the compression because I would have to of ran race fuel. Well today I realized that I live near a small airport, which must have Aviation gas to fill the small planes that come in there. The question is would they sell it to me or do I need some type of permit or lisence to buy it? How much is it where you live?

you don't need a permit to buy it. here in mississippi it cost $2.50 per gallon. i don't know about canada

[Beer_Smurf]

You technically can't pump it into a vehicle. So bring you can not your bike.

[monoxide]

i run it in my Tecate, and it cost's 2.70/gal. but AV gas is only 100octane, and you gotta becareful about the oil you use, because after about an hour, most oils will seperate from the AV gas.

as for not being able to run it in a vehicle, cars have sensors that will not let the engine spark if the fuel has lead in it.

[hondatrikesrule22]

Which oil would ya'll suggest using? I was thinking about klotz.

[CHAINSAW]

I ran AVgas for a little while, and I dont suggest running it at all. If the gas sits for a couple of weeks, or gets really cold, it turns into jelly. When I was running it I had to take off my carb and totally clean it if it had sat for very long...

Just my 2 cents.

-i use R50 and that works good for me.

I am amazed at the amount of folklore, urban legends and just plain wrong information there is out there about AVgas.

AVgas does NOT gel.
Think about this.
Airplanes go up. The higher you go, the colder it gets.
If Avgas was adversly affected by cold, it could not be used in airplanes.

Would the oil have anything to do with it geling(sp) up

Folklore my ass.. I had Jelly running out of my carb! Now it might not of been the cold that did it.. I was speculating. It did gel up.. it could of been a chemical reaction to the oil I was running (Klotz Be-NOL) Av gas is dry, so Im sure mixing it with oil there is something to it.
Either way, it DOES GEL UP!! Ive had it happen in 3 different machines, all with 3 different jugs of the stuff. Either take my word for it, or take your chances.. just remember. I told you so!

[monoxide]

iam behind you 100% chainsaw, i will post pictures if someone would like, the dark yellow gel, thats all over the inside of my carb from AV gas...

[Beer_Smurf]

It seems that you have drawn the wrong conclusion from your experiance.

Take a look at the some pure AVgas in a clean container at the same temps.

I have a can of 100LL (AVgas) mixed with BelRay MC1+ that has been sitting for over six months and is just fine.

Some of our airplanes sit for over a year between flights.

You have discovered a premix oil that doesn't like AVgas, not a behavior of the Fuel itself.

This discovery is a good thing for your fellow riders and should be shared but not used to spread falsehoods about AVgas.

iam not trying to spread nothing, just give information on my experiences with it, and iam sure chainsaw is doing the same. up here in northern Ny its gets alot colder then in Nv, trust me.

You underestimate the coldness of Nevada, up in Reno where he lives it get's pretty damn cold in winter time, pretty close to NY cold. Down in the southern part of Nevada I walk around in shorts and a t-shirt most of the time at this part of the year. It's a world apart from southern to northern Nevada ;)

If your local airport is giving you trouble to buy some 100LL fuel...just tell them it's for a home-built aircraft that you fly out the back of your farm. They will sell it to you!

[Dan Tenn]

If you had AV gas gel, it was due to the addition of something (most likely the oil being used) or improper storage. Beer smurf was right when he said that AV Gas by itself will Not gel. When pure, it is required to have a freezing point of at least -58 C = -72.4 F, but in most cases will be less.

yeah i was just thinking to myself last week when the weather said it was going to get as low as -48 degrees, my 30gal plastic drum of 100LL was going to gel :? it likley is from oil adding to it.

[hondatrikesrule22]

How do I get this stuff? Are you saying I can go into Hobby Airlines here in Houston,and tell the woman behind the counter I want 5 gallons of 747 gas? lol :D Where in the airport do I go for the fuel? :?:

iam sure if you called them or whatever and asked around they could help ya out, make sure you have a green card ;)

[CHAINSAW]

I just walked right in to the airport and bought mine.. no questions asked.
Now we do know the reason why it jelled... it was the mixture of oil to it. And not just any cheap yamalube crap.. Klotz is the only thing I run.. and its about the most expensive stuff out there. Like I said.. I no longer run, and never will again. Use at your own risk, but if you toast your machine, remember ole CHAIN told ya so!

Where people come up with this stuff I have NO idea!!! Just where is this "lead sensor" located??!

[Dan Tenn]

"Just where is this "lead sensor" located??!"

Its in between the blinker fluid resevoir, and the muffler belt tensioner. ;)

You don't want "747 gas" because that is jet fuel AKA kerosene and you bike won't run at all.

Go to the smaller airport and talk to the kid driving the truck that says "100LL" on the side and he will hook you up.
Some airports even have a self serve island where you can use your credit card and pump it yourself just like the gas station.

Oh!!!!!!! I'll have to look for it there!! :D

[sportvette]

instead of busting on the guy why not correct him and spread the knowledge. :oops:

there are no lead sensors. but running lead gas will damage O2 sensors on fuel injected vehicles. then your vehicle wont be able to monitor the fuel/air mixture correctly. ;)

thanks,
mark

Yep. Also on EFI vehicles it will damage catalytic converters....unless, of course, you've all ready done away with yours HAHAHA!

[Dan Tenn]

sometimes you cant pass up an opportunity to do a little ball busting. No harm meant, just couldn't help it. :-D

I agree. THe guy talked like he was about to bet the farm that that was true. I couldn't pass it up.

Geeze i must be dumb, i never heard of a car that does that? I have worked on them all, Porsche, ferrari etc.. even flex fuel vehicles and i have never heard of that.(i guess i should trade in the degrees in automotive technology and chemistry anyhow, to answer your question about av gas, i tried that route and found th results were less than satisfactory. this is why, av gas has a specific rvps(Reid Vapor Pressures) to allow it to atomize properly at high altitude and to prevent evaporation. the wrong rvp fuel will have varing results, you may find that your machine overheats, surges or fouls plugs. all fuels no matter where you live are formulated for that type of environment, in that vein, look at the gas stations and read that the fuels used in the winter(particularly in the north east) are oxygenated. summer are not. I played extensively with blending race fuels in both my motorcycles and my Grand nationals using Toluene and xylene(both easily available) check these links out, they are a good read:

hop this will help every one to understand race gas, oh, if you plan on storing your machines with gas, use race gas, it does not break down for years
