What happened to gasoline in the mid 1970s?

The quick and easy answer is that you get more energy out of ethanol than you do with methanol.

Yes methanol can be made from the things that you mention.

As an aside, the addition of ethanol to gasoline by mandate from Congress resulted in more farmland being used for corn production in order to supply the food stock for ethanol for gasoline. This resulted in higher food prices in both produce, dairy, and beef.

Yeah, that’s just one reason why I’m not for using corn for fuel. Just roughly (because I’m lazy and I don’t want to look it up) how many BTU’s less is methanol?

I know in the small test sample I’ve tried I can go 25% methanol and not change a jet or anything.

Seems it would be more cost effective (if we are set on using an alcohol additive in gasoline) to use a bit more methanol and send it rather than use less ethanol and waste all that farm land to grow it.

What do you think about that??
