mix 1 part xylene 115 oct or 1 part toulene 114 oct to 2 parts 93/94 octane gasoline and you'll have 100octane, wow that was hard.
you can also/should add in 1/10 part Maverls Mystery oil if you are making a big batch
You want links? OK, here's a 231 post thread at DSMTalk about this:
Do a search there on "xylene" and you can read for hours...
imo im gonna stick with the real stuff..to much research has gone into modern day fuels for me to try to 'mix' some stuff up, i love making and fabricating things, but i'd like to see long term effects on these cars with jugs of 'paint thinner' and 'cleaner' poured into dsm tanks of 93 octane.
thats just my $.02
someone prove me wrong, so i can try it as well
Aren't most 100+ octane gas leaded anyways?
93 octane- $1.50 a gallon
You need to mix it 1:1 which will give you an Octane of about 101, which is $2.25 a gallon.
Here you can buy 100 octane for 6.50 to 7.00 a gallon at the pump or 112 octane leaded gas at the track for around 7.00 a gallon ( which you can only fill up if the track is open.
Overseas they use up to 45% Xylene in their gas thats why they have higher octane at most pumps than we do.
Who makes the 109? I was almost willing to put money on the fact that 104 is the highest UNLEADED you can get. VP and Sunoco are the two manufacturers I am aware of. I can get 76 Race Fuel (100 octane UNLEADED) for about $4/gallon.
Lowes, Home Depot.
AVIATION FUEL I use to work at a body shop and we made a mud truck out of a 57 chevy nomad anyway we were sick of driving to the nearest station to get 100 oct.(45 mins away) So we went 6 miles to a small air strip (really small, grass runway and all) and got 112-116 oct. for $ 3 -$3.50 a gal. This was just 2months ago. Don't know if it's the same every where or we just got a good deal but that's what we do. And oh what a sweet smell!!
It does smell nice though...
(for all you emmision legal guys)
anywho, is this fuel safe for my car? it being leaded and all...
You people kill me with these octane ratings. Who buys Avgas with 112 octane--I don't think you can? 100LL is pretty much the standard, and it has a LOT of lead in it compared to auto race gas (even though LL mean Low Lead).
I'd be concerned if you had a CAT instead of a testpipe.
mix 2 parts 93/94 octane fuel to 1 part xylene(115)/toulene(/114) and you arrive @ (93 + 93 + 115)/3 = 100 if you want to run this fuel all the time i would suggest adding in a bottle or 2 of Marvels Mystery Oil it will add back in a bunch of lubricants that you thinned out mixing in the xylene/toulene and not really affect total octane.
