No.
My site has quite a bit of info relating to this http://www.maintainyourcar.com/ It depends on what car gives better fuel economy. Some cars that were designed to run on higher octane will give you better performance when using the correct fuel and your fuel economy. Check with your manufacturer. With a Mercury Cougar You could try 91 octane or 95 octane, at least 91 octane will give you a bit better economy Consider servicing the car too that can help!

If you want to save on gas get a good fuel economy car. If you want a fast car, get a muscle car. You pretty much have to choose one over the other.
No. The charcoal canister does not have a noticeable affect on fuel economy.
