Sorry Chris. I couldn't resist the pun. I think I've heard all the jokes, both clean and dirty, that can be made about my name too. Technically, you are correct. If there is anything in the fuel other than pure gasoline (Now there's an oxymoron for you.) the mass flow of the combustible fuel is reduced. However, I don't think you'll find that the mass fraction of oxygen in any liquid fuel is enough to reduce gasoline mass flow in any significant way. Good luck on the wind tunnel work. Jim
