Anyone know of a website that has info on mixing different fuels (i.e avgas and pump fuel)and what increases in MON are seen for differing ratios?Paul

Where can you still by aviation fuel? Besides being unleaded, our airports won't sell it to non air-heads anymore. I know of no sites offering this information either. I would think that it would be dangerous or have serious liabilities if there were one though. Alex------------------

I DON'T SUGGEST THIS SO IF YOU DO IT YOU DO SO TOTALLY AT YOUR OWN RISK! THIS IS JUST FOR EDUCATIONAL PURPOSES. You can go to a chemical supply house and buy a drum of xylene or toluene (sp ?). You can get it for about the same price as gas. Xylene already exists in gas but in small percentages, this is what you pay for when you buy 92. A person I know used to mix Xylene 20% with 92 octane and then run it in a turbo GN at 20lbs. of boost, making big (800+) power, with no pinging at all. WARNING! THIS IS SOME NASTY ****! THE FUMES CAN BE OBSORBED DIRECTLY THROUGH THE SKIN AND SOFT MEMBRANES (eyes, nose, mouth). DO NOT MESS WITH THIS STUFF EVEN IF YOU CAN GET IT. Here is a link with info on the toxic properties of xylene...
http://www.atsdr.cdc.gov/tfacts71.html Here is a link to Toluene
http://www.atsdr.cdc.gov/tfacts56.html Toluene is also a byproduct of oil refining and producing gasoline. Its a hell of an octane booster also and can kill you equally dead with excissive exposure. ------------------

Toluene is also a 'great" paint remover!  But seriously, if you mix 50% 92 octane with 50% 100 octane race or avgas you will end up with 96 octane (half way between the two). You can do the math with just about any mix. You can buy race gas at most racetracks, and avgas with the right connections at some private airports. Don't try to be a chemist.  SteveW

AMEN to the Above post!Donot mess with these Chemicals unless you trained. Xylene and Toluene ain't user friendly,in fact while using them if you tilt your head sideways that gray matter falling out your ears use to be live brain cells... You have any CAM II outlets nearby..its 108 octane avfuel is 110. BTW Alex I have a source for that and 76 Race fuel.

Jay, You can also buy that at your local hardware store for about $5.00 a gallon.We had a lively "disscussion" about mixing that stuff over at Cliffords earlier this year. I probably will end up mixing and using one of the above but I am trained in the art of using it. A lot of the chemicals I use in the bodyshop here have those ingredients in them.... But as you say DO NOT USE THEM UNLESS YOU ARE TRAINED AND HAVE THE PROPER SAFETY EQUIPMENT!!!!!!!!!!

when I lived outside of Raleigh, NC (Fuquay-Varina), there was an Amoco that sold racing gas, think it was like 108 octane, and 6-8 years ago it was like 3 or 4 bucks a gallon. Not sure if they still sell it...

Thanks for the input guys At this stage I'll steer clear of the chemical mixes. We have avgas available at a local airport. I plan on using that. Is the octane level when mixing avgas and pump fuel linear? for example 50/50(90&110)=100, 60/40=98, 75/25=95 etc.Paul

You got it Paul,The only other point is that you shouldn't mix any more octane than you need. Lower octane fuel is more "volitle" ie. more powerfull, higher octane fuel is less volitle to keep it from pre-detonating under high compression, extra ignition advance (both add h.p.) But use just the right amount of octane, no more, and you'll be "smoking"  SteveW

Gentlemen: If you'd like to take a quick trip over to www.mustangworks.com ; then click on 'technical'; then 'articles'; then 'miscellaneous'... you'll find more 'Gasoline FAQ' and 'Octane Rating' information.

you sure 'bout this Toluene stuff?? I used to have to wash steel ladders before painting at work with that stuff... granted its nasty ,i had lotsa problems around it,but thought that was just me,the other guys never drank it  or anything,but didn't seem to be affected much by it  Anyways...i can buy 100LL Avgas at a small airport,they have an accessible cardlock pump... Mr Visa buys it for me It seems to run my 427 well enough.

I Las Vegas they have racing fuel at the 76 Stations. I believe it was about 102 Octane. Anyway, I thought it would be fun to see how my Mustang ran on it, so I filled it up without lookin at the price. $3.00 per gallon And that was in June 2000 Oh Well, I think it ran a lot better.

Tolune is the stuff that they used to put in model car and airplane glue that got you high. I always wondered why I felt so good when building my models. ------------------

A friend was telling me last night that Avgas has coolant addities in it and that if you run your engine on it and the leave it sit for a while (1-2 weeks) the valves can get slight pitting...is this right?Paul

The one thing that av-gas does NOT have is coolants. The biggest problem you have in an airplane is cold. Thats why the carbs are heated. What he probably means is that av-gas burns colder than regualr gas, which is true but the same can be said for any high octane fuel.It is probably obvious that you want to burn av-gas at altitude, so it is designed to work best in cold, dry, thin air. It does have some top end lubricants in it and that kind of stuff. ------------------

Do Not use Avgas in your car, it has a lower specific gravity and is ment for high altitude ie. airplanes. Your better off with a mix of 20% toluene and 10% rubbing alcohol.My 2 cents, probly not worth a penny.

Hopefully the statute of limitations are up...but back in 1966, while stationed at a Marine Corps air base...all of us...(I mean other guys ..not me)..used to borrow 5 gallon cans of Av Gas, which the fly boys referred to as 115/145, and dump it into our....I mean their muscle cars....and shoot up 301/I-95 every weekend....with no problems.
This may have nothing to do with this post and most likely didn't help performance since these were the days when HI TEST was about 100 octane...and I used to use HESS 101 at a premium price of about .31 cents a gallon.------------------
