http://race-gas.com/ If so what were the results? Just seen this advertised on Rev TV and am curious if it is worth a crap? Thanks in advance. Derek
Lots of guys on the BBF forum I'm on use it. I've heard nothing but good about it. I'd be running it myself if the airports here didn't mind selling me LL100 for $4/gal.
I have yet to find any octane booster that works better than leaded race gas itself. The blending guide says it takes 7 ounces per gallon to go from 93 to 107 octane. So for 30.00, I could treat 4 gallons. What exactly is the active ingredient? Pretty sure TEL is the best octane boost ever used.
I have used Xylene for years, all the Motocycle guys about 10 years ago found using it in their race bikes with alittle Mavelous Mystery oil added at about a 1/20 mix worked excellent and gave about a 6-7 point increase in octane rating At $15 a gal for it which makes the final cost of fuel at about $.75 a gallon more for fuel. You can read all the chemical hi-tech stuff online.
This older guy from about 30 years ago that put a BBF in a Pinto told me that he made his own octane booster out of acetone and moth balls IIRC. I asked him for the recipe but he didn't want to share because he wanted to keep it a "secret". I think I'll do an internet search to see if the "secret" is out there? I'll let everyone know what I find. Derek
Yea, old trick but have no idea if it really does anything, probably more Urban Legend than anything.
When they talk about a point increase, realize they are talking 1/10th of an octane number. That means that if you wanted to treat 20 gallons of fuel and boost your octane from 93 pump gas to 94.6, you would need to use 18 ounces/gallon, or 360 ounces. That is at least 10 of those containers. How much does that cost? When I researched this, I really couldn't learn much more than that. If you mix 5 gallons of 110 leaded race gas with 15 gallons of 93, you end up with 97.25 octane. Race gas still makes the most sense to me, and it is more economical. Octane boosters are a waste of money IMO.
Aviation fuel is not good for our engines due to its design characteristics. It provides no top cylinder lubricant.
Back in the old days (80's), we used toluene to boost octane. It seemed to work really well and was cheap. I have forgotten the ratio but I know it is in one of the old GS-Xtras.
Winner, winner chicken dinner!! Did some innerweb searching and found out that it sounds likes the cheapest and easiest way to increase octane is with toluene which can be cheaply bought at your local hardware store that is sold as certain paint thinners! Who would of thunk that cheap paint thinner would be the octane boost to use, actually it is the same crap that they sell in the small containers with a GIANT markup! Here are mixture formulas I found how to mix the stuff to get your desired octane that can be mixed with gas to cheaply raise octane; http://www.clubwrx.net/forums/engine-modifications/44006-homemade-octane-booster-formulas.html Now there is no reason not to build a 12:1 street sbb 350!

Same info I have but, the down side is that Xylene and Toluene now cost upwards of $25 a gallon. So, it's close to the cost of unleaded race gas in most areas if you want 100 Octane. Here are my calculations for Xylene mixed with 93 octane at $2.60/gallon and Xylene at $25/gallon. 10% mix - 95.4 Octane @ $4.84/gallon 20% mix - 97.8 Octane @$7.08/gallon 30% mix - 100.2 Octane @ $9.32/gallon
That is unfortunate, I'll have to look at toluene paint thinner prices to see if it can be less expensive! I'll report what I find. Derek
Please don't get too carried away when giving advice about adding hardware store Toluene to the tank and expecting consistent results. There is so much variance in toluene paint thinner from brand to brand and batch to batch store-bought stuff, you'd be amazed. It's something I'd never suggest anyone rely on. I did enjoy trying a series of chemicals as octane boosters including toluene and xylene in the 1990's thanks to a friend who managed chemical storage at a local (Unnamed) University Experimental Chemistry Department. They frequently had to restock various hydrocarbons and had to properly dispose of previous unused stuff, and I got some to try. That stuff was the real deal, I think I still have notes on it. It was high molarity, we're talking not touching it, not breathing it, no eye contact, etc. And it worked GREAT in very small doses. The hardware store stuff pales in comparison to the serious stuff so that paint thinner customers can stay alive. It's diluted with any number of different additives. It's marketed as PAINT THINNER for goodness' sake. So to anyone reading, don't get too excited about adding off-the-shelf toluene paint thinner to the tank. It's not what you might think, and the results could very well be all over the place. Devon
LOL The Toulene is something I have been using for 30+ years. It is used in the printing industry to clean ink rollers and dried up ink. This was mainly used on handset type since it dried fast and cuts dried up ink. We also use 99% isopropyl alcohol in our world too. Don't use the Toulene as much now it is too strong and will eat the paint off anything. This stuff was originally called Type Wash and this is a Varn product. I heard about this being used but never tried it. LOL I worked at one place that had it in 55 Gal drum. This stuff will melt Nitrile gloves especially those thin ones.
Sounds like you may have access to the real deal, maybe even economical to use? Very cool if you do! Derek
Here is 5 gallons of toluene for $109.55 that would be $21.91 per gallon with free shipping; http://www.ebay.com/itm/RAE-S-2-Tol...924317?hash=item4d25383c9d:g:M0oAAOSwB-1YtKg2 Looks like the real deal to me and a little bit less than what Ray posted. With a 20 gallon tank 2.5 gallons would be 12.5% and get you to 94.75 octane. Should be good for 10.8:1 with cast iron heads with as low as to I would guess in the 220* @ .050" range and higher. Starting with Sunoco 94 would get it to 96.75, good to I would guess around 11.3:1 with the above dur, @.050" and higher. Will have to look at Amazon to see if it might be even less there or see if a bigger quantity can be found for less? If your not sure of the concentration of the above one, this one claims to be "100% industrial virgin grade"; http://www.ebay.com/itm/CMA-Toluene-1gl-/272732105155?hash=item3f8019a9c3:g:A-0AAOSwd4tULr61 Here is what is written about this one; Toluene is a common solvent, able to dissolve paints, paint thinners, silicone sealants, many chemical reactants, rubber, printing ink, adhesives (glues), lacquers, leather tanners, and disinfectants.Toluene can also be used as an octane booster in gasoline fuels used in internal combustion engines. 100% Industrial Virgin Grade Shop Direct:This product is also sold in 5gl pails & 55gl drums.

Maybe my math is juked, but 2.5 to 20 is 12.5%.....2.5 to 10 is 25%. It is 11 at night and I've been drinking since 10 a.m. however....
Fixed it, haven't been drinking but it is late and to tired to sleep. Still searching for better pricing, may have to be a business with a tax number to buy bigger quantities though? There has to be a cheaper source out there, I try to find it. Derek
Have any of you fellas looking into this stuff gone out to your local airport and seen if they'll sell you ll100 (low lead 100 octane, commonly called avgas)? Like I said, its around $4/gallon here so if I fill up with it 100% instead of 91 non-ethanol, its around $15 a full tank. I mix 50/50, so its 7 or 8 bucks a tank and works waaaay better than a bottle of octane booster and is much cheaper to get up to 96 octane or so. Plus it smells fantastic out the tailpipes.
