I know about the compression and burning capabilities, I'm just trying to understand what is actually in the fuel that makes the difference. Sorry if I wasn't clear in my original question.

So if I want to make regular gas a premium, I just add more of the octane family of hydrocarbons, but what does it replace? According to HowItWorks, there are different families like the octane family, so does regular just have more of the other families like hexane, heptane etc.?
