AVGAS=100 octane low lead=aviation fuel



My Power Doesn't use my 02 sensor so will this be okay for me to run?I'm just thinking of a way to buy cheap race gas.

A friend of mine will sell it to me for 2.10 a gallon.


Is this safe on the motor?

Thanks

It should work allright. ask him if you can get some 100LL thats 100 octan Low Lead. Thats pretty good stuf to use. I htink around here the 100LL runs about $2.40/gallon. Just dont let the DOT catch you using this stuff, i am not sure about where you live but here we have gas tax, and that tax is on fuel that is used for road driving. if they find out people are buying airplane gas thats not being taxed they will get pissed.

ya i ran 100LL no probs at all... i run usually a mixture not sure if its safe tho 5gals of 100LL and 10 gals of 91... i havent had any problems before... but then agian my motor is tired and has low compression on the front rotor...

where do you get your avgas from importboi? i live pretty close to corona and am interested in some.

Only run av if you do not have CAT's!!! This is very important because you will clog a CAT really quick. When they say "low lead" they are meaning low compared to regular av gas. There is still a ***** load of lead in this stuff. Guess how I know?

Evil Aviator

LOL, you are correct, 100LL has about the same amount of lead as did regular leaded automotive pump gas, but I'm afraid to ask how you know that.

Like everything else I have ever learned, I learned it the hard way! Messed up a cat about 8 years ago and was not able to get a legit inspection until $250 later. It was not worth it.
But if you don't have cats it is cheap way to get more power.

I ran 100 octane in my Eclipse GSX last year for street racing in KC and on the way home that night, my motor popped. I am not sure if it was the gas, the racing, or the tuning but she took a **** the one and only time that I ever used it. I can get you all sorts of octane from 110, 114, 118 you name it. I can also get methanol if you want.

Lanechange,where can you get this and for what price?

I get it right here locally in Kirksville, MO. I will get you some prices. Do you want to know by the gallon or by the barrell?

Rx7carl

Yea but wouldnt this be a huge waste of $$$ on an n/a rotary?

Rx7carl

stupid double post

Scalliwag

Ouch!

Resource

I need prices on the gallon and by the barrel.

I have zero Cats and no O2 sensor so it doesn't matter what I run.

I'll get you some prices by the gallon and by the barrell. Scott

We used to be able to go to a small private airport and fill our cars up. That was the way it was all over. I would guess those days are over. I have not tried to in years.

After reading this page and more than a few others, it looks like toluene is the way to go instead of avgas. Who's put toluene in their tank?

Scalliwag

Scalli will wait until someone else tries this! It does sound like the guy knows what he is talking about, but I've been bullshitted before and I will be again I'm sure.

Rx7carl

What about using 80 octane in an N/A rotary? ANy thoughts? Anyone? Bueller?

Scalliwag

Why would you want to even if you could? It's lower octane than pump gas.

80-CU.IN.T

AV - Gas will work but you have to tune for it. You will run leaner. I don't know the BTUs.

Resource

Why would I run leaner?If it's 100 then it should burn slower correct?

HWO

you can run leaner safer, you can run more advance safer, both of which = MORE HP

but as someone said, you have to tune for it.

Rx7carl

Then it'll burn quicker wont it? If 87 is preferred for N/A applications cause its whats availible, then if a lower one is availible maybe theres a gain? I dunno, just asking for any opinions, educated guesses.

Scalliwag

Hmmm, it is just so far out of the normal paradigm that I cannot see that working. I think the slower burn on the higher octane leads to carbon buildup is the problem. As far as performance I am pretty sure that the higher octane gives it more "go-go".
Of course I could be wrong but even the people running "All-motor" class are running racing fuel.
