Buy 5 gals of Toulene from a paint store (if they'll let you).
RON of Toluene is ~118 to 120. From there you can back calculate how much you need using a weighted average formula.
First Eqn.
(93oct)(X gals)+(118oct)(Y gals)/(tank volume) = final octane desired (mid 90s?)
Second Eqn.
X gals + Y gals = tank volume (16.4 gals, IIRC)
From the above two equations (with two unknowns), you can figure out how much Toluene to add based on the final octane you want. I wouldn't go much above 94 or 95...if the ECU isn't programmed to take advantage of it.

Don't buy that junk in the store, it doesn't do anything. Electron Man is right with his
calculations, this works. However, don't do it often cause it could wreck your o2 sensors.
