The refiners have caught on to this trick, they're now pumping extra oxygen into the gasoline like a kid at the soda fountain blowing down his straw.

If you weigh a gallon of gas now it would weigh less than last year, and as a bonus you get to pay more!

Ok, I'll bite. How's that work?

How are they keeping this oxygen that they are pumping into the gasoline from bubbling right back out?
The solubility of oxygen in gasoline is quite low.

Perhaps they are making a froth?
That would not last for more than a few minutes after they quit "pumping" the oxygen.

I'm not sure how the safety guys would feel about them pumping oxygen into the gasoline either. Generally they are trying to keep the oxygen concentration well below the level which supports combustion. They tend to lose money when the refinery blows up, you see.
