Octane Booster Fuel Additive

i got ya here i found this info =)
I used a plastic funnel to pour the xylene from its metal can into a 1 gallon plastic "gas can" -- then I used the gas can to put the stuff in the tank using the normal procedure. The xylene wasn't in the funnel or the plastic gas can long enough to cause any trouble, only a minute or two. I have heard that xylene can damage plastic, but over a period of days or weeks, not minutes.

I did spill some xylene on the ground, and a much smaller amount on the car near the gas cap. The xylene on the ground will evaporate within a day or two, and since the temperature outdoors was well below the flashpoint of xylene, it wasn't at any real risk of catching fire. But I did dump a couple of quarts of water on it to cause it to disperse a little -- it's not soluble in water, but I figured that a larger "oil slick" of xylene in the driveway was better than a small (3-4 inch) "puddle" of concentrated flammable liquid.

The spill onto the car, I also flushed with water, and then wiped repeatedly with non-abrasive paper towels until it was dry to the touch. I didn't see any paint damage. I didn't think of it at the time, but I bet that spraying some WD-40 would probably dissolve the xylene and it would clean right off no problem.

Don't mess with xylene in your garage -- do it outdoors where you don't have ventilation issues.


I wouldn't exceed a 1:3 ratio of toluene/xylene to gasoline, even though some will go as high as a 1:2 ratio. The reason is that toluene/xylene doesn't have any lubricants, detergents, or any of the other beneficial gasoline additives.

Q: How much toluene should I use per tank of gas?

A: Octane ratings can be very easily calculated by simple averaging. For example, the tank of an Audi A4 1.8TQ is 15.6 gallons. Filling it with 14.6 gallons of 92 octane and 1 gallon of toluene (114 octane) will yield a fuel mix of:

(14.6 * 92) + (1 * 114) / 15.6 = 93.4

The Audi A4 1.8T is a good example of a car that has very high octane needs if it has been modified to produce more turbo boost. The base compression ratio of this car is a very high 9.5:1 and when an additional 1 bar (14.7 psi) of turbo boost is applied on top of it, the resulting effective compression ratio is way beyond what 92 or 93 octane fuel can ever hope to cope with. Most modified 1.8Ts running without octane enhancement are running with severely retarded ignition timing and boost.
