I have not been able to verify but found this interesting. Heres the snopes link
http://www.snopes.com/inboxer/household/gastips.asp I don't know what you guys are paying for
gasoline.... but here in California we are also paying higher, up to $3.50
per gallon. But my line of work is in petroleum for about 31 years now, so
here are some tricks to get more of your money's worth for every gallon..
> Here at the Kinder Morgan Pipeline where I
> work in San Jose , CA we deliver about 4 million gallons in a 24-hour period
> thru the pipeline. One day is diesel the next day is jet fuel, and gasoline,
> regular and premium grades. We have 34-storage tanks here with a total
> capacity of 16,800,000 gallons.

> Only buy or fill up your car or truck in the
> early morning when the ground temperature is still cold. Remember that all
> service stations have their storage tanks buried below ground. The colder
> the ground the more dense the gasoline, when it gets warmer gasoline
> expands, so buying in the afternoon or in the evening....your gallon is not
> exactly a gallon. In the petroleum business, the specific gravity and the
> temperature of the gasoline, diesel and jet fuel, ethanol and other
> petroleum products plays an important role. A 1-degree rise in temperature
> is a big deal for this business. But the service stations do not have
> temperature compensation at the pumps.

> Gasoline evaporates faster than you can imagine. Gasoline storage tanks have
