Tips For Pumping Gas - Good Info
Got this email yesterday, it has some pretty good info on how to save some money at the pump and how to make your gas last a little longer 
... Thought it would be a good idea to share with you guys since our cars inhale gas like crazy, Especially us guys with the V8 !!
Interesting information from a Gentleman in California
I've been in petroleum pipeline business for about 31 years, currently working for the Kinder-Morgan Pipeline here in San Jose, CA. We deliver about 4 million gallons in a 24-hour period from the pipe line; one day it's diesel, the next day it's jet fuel and gasoline. We have 34 storage tanks here with a total capacity of 16,800,000 gallons. Here are some tricks to help you get your money's worth:
1. Fill up your car or truck in the morning or at night when the temperature is still cool. Remember that all service stations have their storage tanks buried below ground; and the colder the ground, the denser the gasoline. When it gets warmer gasoline expands, so if you're filling up in the
afternoon or in the evening, what should be a gallon is not exactly a gallon. In the petroleum business , the specific gravity and temperature of the fuel (gasoline, diesel, jet fuel, ethanol and other petroleum products) are significant. Every truckload that we load is temperature-compensated so that the indicated gallonage is actually the amount pumped. A one-degree rise in temperature is a big deal for businesses, but service stations don't have temperature compensation at
their pumps.
2. If a tanker truck is filling the station's tank at the time you want to buy gas, do not fill up; most likely dirt and sludge in the tank is being stirred up when gas is being delivered, and you might be
transferring that dirt from the bottom of their tank into your car's tank.
3. Fill up when your gas tank is half-full (or half-empty), because the more gas you have in your tank the less air there is and gasoline evaporates rapidly, especially when it's warm. (Gasoline storage tanks have an internal floating 'roof ' membrane to act as a barrier between the gas and the
atmosphere, thereby minimizing evaporation.)
4. If you look at the trigger you'll see that it has three delivery settings: slow, medium and high. When you're filling up do not squeeze the trigger of the nozzle to the high setting. You should be pumping at the slow setting, thereby minimizing vapors created while you are pumping. Hoses at the pump are corrugated; the corrugations act as a return path for vapor recovery from gas that already has been metered. If you are pumping at the high setting, the agitated gasoline contains
more vapor, which is being sucked back into the underground tank, so you're getting less gas for your money. Hope this will help ease your 'pain' at the pump.
5. Do not top off your gas tank, when the pump shuts off, do not keep trying to add more gas..................a friend who owns a gas station says that by doing th is, you are actually giving the next customer a $1.00 worth of gas. The gas you pump stays in the hose and never makes it to your tank...........good to know.

Lol yea when i first got this in my email I was like yea yea, i hear "tips" on how to save gas all the time ... But when i read this i was like damn I do everything wrong except #1 ... I DO fill up my tank at night (usually around midnight when I'm on my way home), but i also have filled up when the tanker was there pumping gas into the station, I always wait till my gas light comes on and the needle is on E to fill up, I ALWAYS have the gas pumping at full blast, and I ALWAYs try to top off the tank

This was posted on the 2IS forum a while ago I believe and some of it was proven to be untrue and some were proven to be not worth the savings for all the effort needed to do.
Like for me, if I filled up when my gas tank is half way, i'd have to put gas every 2-3 days and that's just too time consuming for me.

The rest of the tips were cool, but there is no way I'm pumping at the slow setting to save a few cents of gas. It already takes long enough to pump gas as it is, especially when you're paying in cash at a station that makes you pre-pay (I can't stand this!). If you give them a $20 the gas comes out fine for the first $19.50 and then the last $0.50 takes FOREVER to come out of the pump!

the density of gasoline barely changes b/t night and day temperatures, I doubt it even matters, look into gasolines coefficient of expansion and I bet you it wont matter in the end
