Bought a gallon of 100% xylene at Lowes this morning for $10.00. - 117 octane. See Danno's racer-x site for more info on xylene. Home depot gets $10.00 a quart.

Tolulene (sp?) makes a good octane boost, is this also what xylene is used for?

And if you have some xylene left over, you can always use it to remove the hood liner adhesive as well.

Check Sherwin Williams. Sometimes they have both Xylene and Tolulene in 5 gallons for around $38-$41.

Yeah, xylene is even better at 117-octane vs. 114 for toluene. Someone actually mentioned a while back that they were asking for toluene at Sherwin Williams and the employee asked them if they were using it for octane-boosting. Then he referred them to the xylene they had that was even cheaper than toluene. The Home Depot near me had toluene in 1-gal cans for $5.50/each.

I get Toluene at Sherwin Williams for $5.35/gallon. $10/quart????? Go to a for real paint store for your fuel additive needs.

Isn't it possible to run higher concentrations of toluene (20%-25% max) as opposed to xylene? (10%-12%)
Can anyone with an EGT gauge verify higher temps while using either of these?

BTW, Sherwin Williams quoted me $208 for a 55 gallon drum of Toluene

Just curious...

Is it possible to mix 40% xylene and 60% gasoline (93 octane) to create a blend? Will it have negative effects on my car?

Thank you. <img src="graemlins/yltype.gif" border="0" alt="[typing]" />

"Is it possible to mix 40% xylene and 60% gasoline (93 octane) to create a blend?"

Hmmm, that would give you a 102.6 octane mix. Considering that the mid-'80s F1 monsters used an 80-84% toluene mix, I would think it's OK. These aromatic additives are actually less reactive than regular straight-chain hydrocarbons (hence the knock-resistance and octane boost). Only issues are fuel density and optimum air-fuel ratio. Like with race-gas, you'll have a denser mixture and the resultant air-fuel mixture will be richer than with normal gas. So you'll have to lean out your mixture somehow to get the most of the mixture.

What ratio mixture would one need of Xylene to get, say, 104-105 octance with 93 gas?

Dave951m - Sherwin Williams has tuluon for $10.00 a gallon also, in my area same as Home depot - $10.00 a quart is for xylene at Home Depot.

Danno

Hey, STOP BUYING THIS stuff !!! You're snapping up the entire supply and driving up the prices for the rest of us...

Levish

I believe the only reason to use Toluene over Xylene is that Toluene would have less (if any) negative effect on the emmissions system

But I forgot that the 951 is more than likely a ODBI car and that most cars have had emissions systems "replaced"

Danno

I think the 951 is even pre-OBD1...
