Additive to gas

ever since ethanol has been added I am getting less MPG

Is there any kind of additive available to improve this?

Nope. Sorry. Ethenol simply contains less energy than gasoline.

Yes, gasoline.

Dilute the gasoline/ethanol mixture with a large quantity of gasoline, and your mileage should return to normal.

Sorry–The devil made me do it!
