What you're really getting when you mix your own E40

I went on vacation the other weekend. Because I've got a minivan full of kids, overloaded with all their crap, and I love to drive fast, I fill up the van with premium fuel.

I want as much power to pass as I can get!

So on my travels, I stopped at Shell to gas up.

Lo and behold... Shell sells 94 octane gasoline. It was 10 cents more per gallon than 93, which is 10 cents more than 89, which is 10 cents more than 87.

What do I get when I mix my own E40? 94 octane.

I'm going to have to redo my cost savings calculations to reflect that 94 octane is 30 cents a gallon more than 87, instead of doing it based on the 20 cent premium that 93 costs.
