When I worked for a major oil company we figured there was just under a penny extra profit in the "shrink" of gasoline. We never counted this penny as income because it was never collected by the company at wholesale; it was simply a "pennysworth" that disappeared between the refinery loading rack and the retail gas station as the gasoline cooled down.
Heavy oils, including N6 fuel, is sold as "net gallons corrected to 60 degrees" no matter what the temperature is at loading. The API pulishes a conversion scale for these heavy oils based on API gravity and temperature. If Ralph Nader & Company want to increase the cost of gasoline by removing and replacing every gas pump in the US, they might borrow a few of Ralph's millions to help do it.

Why did the movie "Office Space" just pop into my head? LOL!
