Gas Cap and Calculations
COBESGT, what's that gas cap you have? Can we see a larger photo of it and your car?
If I remember my college chemistry, toluene is a solvent, used for cleaning metal.
The gas cap is a UPR Product. Gezz, I'm impressed that someone else would like to see more pictures of my car. I'm attaching a picture of the gas cap and if you would like to see more pictures of my car, just let me know what angle.
As far as the Toluene goes, I did some simple equations using a dilution calculator and found that you would need to mix 3 gallons of Toluene with 12 gallons of 87 Octane gas to get a mixture of 92 Octane. See my simple calcs below:
Toluene = 112 Octane rating x 3 gallons = (336)
Reg Gas = 87 Octane rating x 12 gallons = (1044)
Desired Gas = 92 Octane rating x 15 gallons = (1380)
(112x3) + (87x12) = 1380, thus giving you a 92 Octane Rating mixture.
Now let's say a 1-Gallon can of Toluene = $5 (I really have no idea what it costs), 87 octane gas costs $3.73/gallon and 92 Octane Gas costs $4.13/gallon.
($5x3) + ($3.73x12) = $59.76, Toluene & 87 Octane mixture cost
($4.13x15) = $61.95, 92 Octane cost
So, to make a long story short, after I did all the calculations, $2.19 is not worth my time, effort, or worries.
