For those of you who require more octane than can be found at the pump, are there any products that you've tried and found that it worked as advertised? I can easily get ethanol free gas where I'm located but it's mostly 89 octane.
 
Find a source for VP Racing Fuel locally, buy a few 5gal cans, and "cocktail" it in. I'm lucky I guess, as they sell it at the local gas station, down at the corner...
 
I mix 91 octane/ 10%ethanol California catpiss with Arizona 100LL about 50-50. The az avgas is almost the same price as the pump cat pee.
Edit: to the best of my knowledge, there is NO ethanol-free gas available at the pump anywhere in california.

Agreed, I have access to bulk 112 so I buy (3) 5 gallon cans and cut a couple of gallons of it into a tank of 93 pump gas. 3 cans is usually enough to last me through the 3 seasons since I don't drive it every day. As far as I know, none of the so called octane boosters over the counter are worth buying
 
I do like VanDan, Lucky for me that the next door neighbor is a drag racer and at the track allot. He brings me the 5 gallon cans when needed.
 
Has anyone tried Klotz octane booster? Did a little research and it already has a lead substitute in it as well as being able to tailor the amount of extra octane needed by adding 1 or more ounces per gallon.
 
I’ve used Fastgas in the past. Hard to tell if any benefit. Seemed to run a little better.
 
Check the local availability of Sunoco racing fuels both unleaded and leaded...not inexpensive but good blended with 93 octane pump gas.
www.sunocoracefuels.com
The Supreme 112 octane leaded is nice. Or if you want unleaded it is offered as well. Go to the link then browse the the offerings then call them to find a local outlet.
IMO any of the "octane boosters" marketed are NFG; many add manganese bearing compounds which are death to spark plugs. They only raise the octane level 1 or 2 points; a 16 oz bottle costs ~ $ 8. You would need to add several gallons to be effective. Low lead av-gas is said to be effective but availability is marginal at best but depends on if you can buy it and where.

Best bets IMO and from experience is blending pump premium no ethanol with Sonoco Turbp Blue (or whatever race fuel) or pump premium no ethanol with AVgas. There have been a few times over the years where cruising and racing have been part of the same out of town trip, so if I have to use 90/10 premium, instead of adding Marine Sta-Bil 360 to fight the negative effects of corn piss, I use a Royal Purple product that handles the ethanol AND provides a number or 2 bump in octane.
Most all of the time around home and our local drag strip, 93 octane no ethanol 100% dino juice gasoline is all it takes.

Marine Sta-Bil is great for storage use, to be added to gasoline to prevent condensation from forming and absorbing if it forms, but if you read the label, one of the components may be METHANOL, which is a derritive of alcohol. Chemically, Ethanol is: C2H5OH and METHANOL is: CH3OH. There may be Isopropyl alcohol (C3H7OH) added as well. There are other rust inhibitors added to prevent corrosion. Methanol in high concentrations is reported to cause degradation of certain rubber and elastomeric compounds, like fuel pump diaphragms and certain carb parts. The exact formulation is proprietary. By adding Sta-Bil you're adding a small percentage of alcohol. Perhaps you can use one of the Sunoco fuels noted....strictly for "off road" use only...of course.

When we first got the GTO, I bought a 55 gallon drum of Sonoco Turbo Blue race fuel. 109 octane, lead additive, for off road use only,....of course...
As it turned out, the biggest (but not only) reason for the bad detonation was the timing was way too advanced by the previous owner. :BangHead: DUH! I should have checked that FIRST! :BangHead:
 
Look up Boostane
Thanks for the info.... but for my money, I want to know what I'm putting in the tank. The products noted state their ingredients that increase the octane level...but do not say how or by what means thus is achieved. I'm wary of boosters with benzene or other oxygenates like MTBE (Methyl Tertiary-Butyl Ether ), although they raise the octane levels in the fuels that they are blended with, the octane level increase directly proportional to the amount added. The other compounds noted are not really called out or in what concentration.
Ethanol (and methanol) increases the octane level but has half the energy value of gasoline so you need to increase the amount being burned by 2x.
During the cracking of crude oil and its subsequent blending with alkylated compounds to increase the R+M octane (Research # + Motor #/2) rating of the end product. Alkylation is used to convert isobutane and low-molecular-weight alkenes that occur in the refining ptocess into an alkylate, a high octane gasoline component. The process occurs in the presence of an acid such as sulfuric acid or hydrofluoric acid as catalyst. Most all of the refineries use this process to create this blending ingredient.
For my money, I'll stick with a known product....like what Sunoco fuels shows....prices are similar to the products you note. But Sunoco makes available the MSDS (composition and safety aspects information) info....just my opinion of course.

Anybody know anything about this stuff? It's advertised as having real lead (59.4 grams per gallon.) I would think it illegal to sell but if you look around the web, it's available from several places and reviews indicate that it works and does have TEL.
Curious if anybody has used it, TEL is nasty stuff but if handled properly could be cheaper and an alternative to mixing race fuel into the tank. Chime in!

That is one of only about 3 serious octane boosters that I was considering, but I still have some 109 Sonoco Turbo Blue left, and I don't really need more octane than the readily available....
:thumbsup: 93 octane 100% gasoline premium
grade fuel only 5 minutes away! :bananadance:
There's the local airport, where I can fill up a portable fuel container with 100 AVgas.
BWA-HA-HAAAAA :bananadance:
Torco is another I looked closely at and seems to be outstanding.

Yeah, the only non ethanol gas available near me is low octane 87 and it's a buck more a gallon than the corn juice stuff so not a viable option for me. 100LL avgas is available but when I compare the cost, I can do better with 112 and use less per tank. Still curious if anybody on here has used the Kemco stuff and can give me a review

I am fortunate enough to have an airport 8 mi. from my home,can buy 101LL for $4.05 gal,no need for me to go with anything else.Been running is straight for 30 + years,never any issues.
 
What "good things" have you heard? Do you use it in your csrs?
Exerpting from the Summit advertisement: ... (it) presumably the product...transform it into high-octane, high-energy, track-grade racing fuel! It contains many chemicals that fall into three primary groups: fuel hydrocarbons, oxygenate, and organometallic compounds.
Fuel Hydrocarbons is a catch-all term, that can mean anything with a carbon molecule sttached, like ethanol, methanol, benzene, kerosene, etc. Oxygenate compounds can be MTBE (Methyl Tertiary Butyl Ether), nitomethane (CH3NO2) and its derritives. Organometallic compounds can also be lead (tetraethyl lead- C8H20Pb) and or manganese salts, (methylcyclopentadienyl manganese tricarbonyl (MMT or MCMT) is an organomanganese compound with the formula (C5H4CH3)Mn(CO)3. Initially marketed as a supplement for use in leaded gasoline, MMT was later used in unleaded gasoline to increase the octane rating).
Personally, I would NOT use this stuff in my cars. I'll use one of the Sunoco race fuels noted, either leaded of unleaded, depending on one's personal preferences and blended with 93 octane pump gas. I use a leaded product, usually Sunoco Standard leaded, 110 octane or Supreme leaded 112 octane. Because its consistent and reasonably available at a price that is high (relative), but due to my low consumption rate (2-3 five gallon cans/year), not really a factor. Just my opinion of course.
