My mass flow logic is completely sound. I wasn't assuming that the O2 was dissolved in the gaseous state. If a hydrocarbon molecule has an oxygen in it, that oxygen is taking up space (and mass) that could be replaced by carbon and hydrogen. If the amounts are signifigant enough to alter the products, they are signifigant enough to alter power output. C -- Dr. J.
