nope.
My thinking is just fine and nearly flawless. Your thinking is confused, however. Look up the word “oxygenate”. Here, I’ll even help you...

The figures below are not lying. No matter how you slice it, the greater the percentage of oxygen (and indeed hydrogen) that is present in the fuel, the lower the amount of energy available in the fuel. It is nearly akin to that particular carbon already being burned. Compare, especially, Ethanol with Methanol, which has an even greater percentage (by weight, number) of oxygen already combined.
