That was a very interesting read. I have three questions that I've been wondering about.
How do fuel companies produce gas with different octane ratings, and does it cost anywhere near the extra thiry cents per gallon that we pay, to propduce?
So if the octane rating is the way gasoline behaves as opposed to a mixture of octane and heptane, does 113 octane fuel take 13% more pressure to detonate than pure octane?
Also, how approximate are the ratings at the pump? I assume that it's impossible to make a perfectly uniform mixture, but how close is it?
