    for all the guys running an older motor or a newer one for that matter and want a cheap octane booster try xylene.2 oz. per gallon turns regular into premium.I work at a paint store and I have been using it for about a year now with great results.xylene is cheap if you go to the right place and if you read the ingredients on a bottle of "104 octane booster"it is mostly xylene.buy premium add 2 oz. per gallon and hold on.it really works.my mileage went from 11 mpg to almost 15 to boot!!

    I use toulene.
    Toulene
    R+M/2...114
    Mixtures with 92 Octane Premium
    10%...94.2 Octane
    20%...96.4 Octane
    30%...98.6 Octane

    Pretty similar to xylene. Xylene has a higher R=M/2
    Xylene
    R+M/2...117
    Mixtures with 92 Octane Premium
    10%...94.5 Octane
    20%...97.0 Octane
    30%...99.5 Octane
    Get mine at paint stores too.
    Its fun to experment with. You can really advance your timing without pinging. I like to use it for FId computer controled cars because you can bump up the base timing a lot and it wont ping.The ECM doesn't see any ping so it doesn't retard the timing.
    Works wonders at the track or fooling around on saturday night /forums/images/graemlins/wink.gif
    Tolulene is the purest hydrocarbon there is.Gas is mostly tolulene so it wont hurt 02 sensors or Cats.
    Yur right about the off the shelf octaine boosters. They are all xylene or toulene. Some have paint thinner, diesel, kerosene and ATF or dye to add a little color in the mix. Also the commercial boosters that claim to raise the octaine 5 points or more really dont do much. A point is only .01. So if you buy a booster that says "Raises octaine 5 points or more!" all it is doing is raising 92 to 92.5 octaine.
    Buying the real stuff (xylene or toulene) is way cheaper.
    If anyone out thete has a Turbo'd car. Try it! You will be impressed. espically if it is chipped or running higher than stock boost.

    Try ether, they put that in gas to raise the octane. E-85 (15% ether) gas at 87 octane was probably like 84 octane with no ether.

    Uhh, doesn't the E in E-85 stand for Ethanol? /forums/images/graemlins/eek.gif Ether evaporates VERY quickly.

    so how does it come ? By the ounce, in a gallon and can I get it at the local hardware store since we don't have an exclusive paint store here. (Alaska) so for 20 gallons of gas I would have to add 40 ounces seams like alot. I have to run premium and a bottle of 104 per tank in my beast because of the compression. So anything cheaper or better would be a big help for me. Also what's the name brand that you buy it under.... I mean what do I ask for when I got to the store here? THX Mike

    it comes in a gallon, and any hardware store that sells paint should carry it. just ask for xylene or toulene.

    Okay, so how much is a gallon?

    Right now i mix in R+M/2 114 octane 76 race fuel for my 11:1 big block. Thats $4.50 a gallon.
    It smells GREAT idling at stoplights. /forums/images/graemlins/grin.gif

    wow it's 8.50 a gallon here..... that is [darn] stupid!! That's the case price! I just called the hardware store..... so which is better to run the Xylene or the Toulene? /forums/images/graemlins/bow.gif

    Yea, any good hardware store carrys both... its about $7-8 per gallon mineral spirts is like $2 a gallon I wouldent try that one /forums/images/graemlins/eek.gif but back to the subjust $8 for a gallon isent bad because a gallon will last a long time.
    Also ive heard Xylene makes your tires SOFT if you soak them in it

    R+m ??? what does this mean I've seen it here mentioned several times ... excuse my ignorance. So I just got back from the hardware store and bought a gallon or Xylene BUT it was noted on the container to be medium strength cleaner and the other stuff they had was Methyl Ethyl Ketones , this was noted to be high strenth and so is this stuff better to use and what type ratio should I use?? Logically it seems that this would be better?? /forums/images/graemlins/dunno.gif

    if it takes 40 ounces for 20 gallons then that would be 3 tanks per gallon and that makes it about 3 dollars a tank.....much better than 8 dollar bottle of 104 which still doesn't cut the mustard unless the timing is cranked down, BUT if I can use the Methyl Ethyl Ketone stuff and mix a smaller amount that would be great, Comp. ratio is around 10.5.1 maybe a little more and it's pretty much my DD. Don't really care to drive the wife's pink escort.....LOL /forums/images/graemlins/histerical.gif Do I have to worry about burning a hole in my KB pistons and do I have to worry about washing down the rings with to much of this stuff in the gas ?? THX for all the info...... /forums/images/graemlins/woot.gif

    The (R+M)/2 is a fancy way of saying that they average the two methods of determining octane.

    One is Research -- that's the "R" -- and the other I forget, but obviously starts with M. The two methods have two different results for the same sample of gas... so if one has an Research Octane of, say, 90, and has an M Octane of 80... the avergae is 85 (doing that in my head, damn I'm good at math /forums/images/graemlins/smile.gif)) so that's what posted, 85 octane.

    As for the other, I try not to put into my car or me things I can't pronounce. Methyl ketane goat cheese or whatever sounds frightening, and unless you're an organic chemist, I'd be wary.

    I knew a girl that was multi-organic once...

    Don't use M.E.K.it won't do the same thing.The solvency strength is greater,but it does not do the same thing in a combustion chamber.not quite sure why.I picked up the xylene trick from an old boy,must've been 90 years old.He comes in one day looking for xylene and I asked him why.he said that xylene is the only thing that ever worked for him back in the day,when he used to race his '40 ford coupe...BRAND NEW !! xylene seems spendy(unless you get the employee discount /forums/images/graemlins/grin.gif)but even at 9 bucks a gallon price the 104 crap in a gallon. 3 dollars something for a half pint?? 3 x 16 = 48 freaking dollars a gallon and it does maybe 25% what the pure xylene does.sounds pretty cheap to me.

    <<it comes in a gallon, and any hardware store that sells paint should carry it. just ask for xylene or toulene.>>

    Bad Idea.

    You are actually introducing solvents into your fuel that will corrode your seals & fuel system parts over time. They also do a nice job of eating the nylon sock on the fuel pickup in the tank. They also will strip away the engine oil off of your cylinder walls. Dry cylinders mean more ring ridge, bore scoring, and scuffed pistons.

    There's a reason that these solvents are cracked out of the crude oil and disposed of. (disposed of in pretty bottles and sold at autozone ) If they were beneficial, they would be left in. They're harmful, and only suitable for paint thinners. I'm not disputing that they raise octane, they do, it's just that octane doesn't make power, and the side effects will hurt your trucks over time.

    E-85 is 15% gasoline and 85% ethenol.

    R = research octane
    M = motor octane
    R+M/2 is simply an average of the two.

    If you think that adding toulene is a bad idea then you better stop using unleded gasolene and switch to pure oil. 92 unleaded octaine can leagaly be as much as 45% toulene. Toluene is the purest of the hydrocarbon family made up of only Carbon and hydrogen. It wont hurt seals, fuel systems,plasiic, nylon,or tanks any more than modern gasolene will. It has been used to boost octane by the oil companys since they Phased out leaded gas. It is very stable and clean burning under high loads. Altho I dont recomend running a lot of toulene unless you have a high compression engine that is running a lot of boost. Smaller ammounts of 5-10% will not hurt a stock engine.
    Toulene is also one of the main components of TNT (trinitrotoluene) /forums/images/graemlins/eek.gif
    Maby thats why the old F1 car people called it "Rocket Fuel" F1 cars back in the 80s ran on almost pure toulene.
