HI all
I recently received this from one of my friend's co-worker who works in the petrolem industry. I am not sure if anyone out there like a Chem Engineer or chemist out there that can verify this. Please read on and let us all know if this is true or not?
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.

When you're filling up do not squeeze the trigger of the nozzle to a fast mode. If you look you will see that the trigger has three (3) stages: low, middle, and high. You should be pumping on low speed, thereby minimizing the vapors that are created while you are pumping.
All hoses at the pump have a vapor return. If you are pumping on the fast rate, some other liquid that goes to your tank becomes vapor. Those vapors are being sucked up and back into the underground storage tank so
you're getting less worth for your money.

One of the most important tips is to fill up when your gas tank is HALF FULL or HALF EMPTY. The reason for this is, the more gas you have in your tank the less air occupying its empty space. Gasoline evaporates faster than you can imagine. Gasoline storage tanks have an internal
floating roof. This roof serves as zero clearance between the gas and the atmosphere, so it minimizes the evaporation. Unlike service stations, here where I work, every truck that we load is temperature compensated so that every gallon is 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. DO SHARE THESE TIPS WITH OTHERS!

Its pretty much all true.

I've come across this before.

I do fill up on the slowest setting when it's not terribly cold outside. But I usually forget to fill up in the morning. O well. I wonder how much of a difference it makes?

So folks up north get more gas for their money?

I wonder how true the sediment stirring thing is, AFAIK every pump I have seen has a filter so how would this be an issue? As far as the other tips, I would imagine that it could make a small difference on a large scale but with 10-15 gallons, I don't think so. Ever fill up a lawn mower or any other small engine with gas? You could leave the cap off a tank for hours and the gas tank would still be at the same level.

Here’s some interesting stuff on this topic, which has been debated for some time:
