Octane Booster - brought over from other site

How to make your own octane booster (this is the basic formula of one of the popular octane booster products). To make eight 16 ounce bottles (128 oz = 1 gal):

100 oz of toulene for octane boost
25 oz of mineral spirits (cleaning agent)
3 oz of transmission fluid (lubricating agent)

Notes:

1. Toulene: Common ingredient in Octane Boosters in a can. 12-16 ounces will only raise octane 2-3 *points*, i.e. from 92 to 92.3. Often costs $3-5 for 12-16 ounces, when it can be purchased for less than $3/gal at chemical supply houses or paint stores.

2. Xylene: Similar to Toulene. 12-16 ounces will only raise octane 2-3 *points*, i.e. from 92 to 92.3. Usually mixed with Toulene and advertised as *race formula*.

3. Methyl-tertiary-butyl-ether (MTBE): Oxygenate. Very common in octane booster products. Has lower BTU content than toulene or xylene, but oxygenate effect makes the gasoline burn better and produce more energy.

4. Methanol or Ethanol: Methanol is wood alcohol. Ethanol is grain alcohol and found in Gasohol in 10% ratios. Both alcohols are mildly corrosive and will eat gas tank linings, rubber and aluminum if used in excessive ratios. Main ingredient in "Gas Dryers", combine with water.

5. Isopropyl Alcohol and Tertiary Butyl Alcohol: Similar to Methanol/Ethanol. Isopropyl Alcohol is simply rubbing alcohol.

Thanks for the Info, but I would be very cautious putting this info out there for anyone to use. Some of those chemicals are very carcenogenic and are strictly regulated!!!

Toluene and Xylene are 2 of the worst!!! Need to be very careful how you handle this stuff!! Unless you don't care what your next born is gonna look like!!:questionmark:

Just a little info!! :idea:

Yes, don't drink and drive either.:dontknow:

Gladly that stuff wasn't included in my daughter's Fisher Price chemestry kit.

Just putting it out there incase someone wasn't familiar with the hazards of this stuff. I am sure the majority of the folks on this forum are already familiar with these chemicals. I know anyone who has an electrical background is very familiar with them.

I worked with Fiberglass for many years and these chemiclas are common to the industry. I have several friends who have some serious health issues from working with this stuff. Just kinda of felt compelled to say something!!

Wasn't anything personal!!

Hell, I've already been clipped. Bring it on.

A respirator, and skin and eye protection would be fashionable accessories when handling any of that stuff for sure.

Oh, and no smoking either. :ahhhhh:

Speaking of Chemicals, this is an interesting topic. Anyone tried this first hand?? http://www.pureenergysystems.com/news/2005/03/17/6900069_Acetone/

rock on

I've been doing a bit of research on Toulene. Anyone out there using this stuff to boost octane levels? From what I read Toulene can be added straight to 93 octane and is safe to run with out adding any other additives correct? How much toulene would one add to a 1/4 tank to be in the 103+ Octane range? I am inquiring because I'm probably going to be dropping in some larger pills soon and race gas at the pump is way more expensive that this seems. Thanks for any info.

Where I live I can just pull up to the 110 Octane pump and buy all the race gas I need. :dontknow:

Yes but isn't it leaded??? Do guys on here mix leaded in when they need the high octane. If it is ok I could do it around me also, but I have heard of a few bad things possibly happening to your motor.. Pluged injectors is one of them..
the highest unleaded I could find is 107 to 110. But leaded goes really high.
I could really use an easy way to get my octane up when I want to run high boost.

Yep you can get 98 (unleaded) at Sunoco down here in Florida... at the pump. :rock: Frickin' $6/gal tho!

About the only thing leaded gas will do to one of these motors is plug the cats . I have never seen any other problem and it's not like lead particals are big enough to plug injectors .

I thought I heard something about Leaded Fuel being bad for valve-guides. :dontknow:

Lead is good for the guides.

As HotRod Mike said, the lead will poison the cats and kill them with use.

Leaded fuel will shorten the life of the O2 sensors, If you use leaded fuel O2 sensors will become a maintenance item just like oil and spark plugs.

Lead is GOOD for the valve guides as the lead acts as a lubricant for the stems and guides.
Lead is also good for the valve seats as it cushions, the valve to seat contact.

The residual effect of running leaded fuel stays on the parts for a while ( guides, valve stems, and seats ). It also stays on the O2 sensors and cats which is bad.

yeah but how much a gallon for that !!!???


the only place i know of around here is at the track itself and they charge a premium!

I've heard the same about the O2 sensors. Would have to replace them frequently.

but is it ok/safe to add only toulene to 93 ocatne to boost the level for race only applications w/ nitrous? how much do you add to say 5 gallons of gas to get the level up there?

FSTJACK, you saved me a post, I was going to answer the first three questions exactly as you did.

One more thing that should be noted. If you dont hear detonation at full throttle now, raising you octane will only decrease your power. Your PCM doesn't adjust for changes in O2 readings at full throttle, it's in open-loop mode. So if you don't have a custom tune to take advantage of the extra octane, you're wasting your money. However, it does smell good. :rock: Just don't run too much or you will poison your O2 sensors (as FSTJACK said).
