My wife got this email and forwarded it to me so. I don't doubt the actual science stated but I do doubt that it would make any difference in how much gas you get when you fill up.
I don't know what you guys are paying for gasoline....

actually the exact amount. Another reminder, if there
is a gasoline truck pumping into the storage tanks
when you stop to buy gas, DO NOT fill up--most likely
the gasoline is being stirred up as the gas is being
delivered, and you might pick up some of the dirt that
normally settles on the bottom. Hope this will help
you get the most value for your money.
