a friend sent me this. Some interesting points.


Buying Gas The Smart Way.

TIPS ON PUMPING GAS
I don't know what you guys are paying for gasoline.... but here in California we are paying up to $3.75 to $4.10 per gallon. 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 mode, 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 of the 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. 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.
To have an impact, we need to reach literally millions of gas buyers. It's really simple to do.
I'm sending this note to about thirty people. If each of you send it to at least ten more (30 x 10 = 300)...and those 300 send it to at least ten more (300 x 10 = 3,000) and so on, by the time the message reaches the sixth generation of people, we will have reached over THREE MILLION consumers !!!!!!! If those three million get excited and pass this on to ten friends each, then 30 million people will have been contacted!
If It goes one level further, you guessed it..... THREE HUNDRED MILLION PEOPLE!!!
Again, all you have to do is send this to 10 people. How long would it take?

they say volume corrected to 15 Celsius, imagine if big rigs filled on low speed?

In them hills.
What was the temperature outside when you filled your tank?
B/C a 120L vessel will hold more hydrocarbon at -15 C than at 30 degree c.
So if your tank is only 112L and you filled with 121L it just means the temperature correction on the pump is working.

That filling on low is BS, the pumps have positive displacement meters whose accuracy is unaffected by the rate of flow.

But then again this Instrumentation consultation is worth what you paid for it, don't believe what the internet tells you ;)

in Dease Lake there is only one pump and in the summer I can fill a 20 litre can with 25 litres , there should be a law where the pumps are calibrated every 12 months just like commercial vehicals

hmmmm now have you ever filled your 20 liter can to the 20 liter mark on the jug? yes it has a mark, if ya get 25 liters then I'd believe ya, you are likely filling the expansion area of the can, could be interesting when it gets warm. may just see all your hard earned money evaporate down the drain.


if you register a complaint, i think they will check the pumps accuracy, at least what i was told.

back in the early 80's I used to work for ICG in Golden pumping gas after school. We were not allowed to say but about 3 inches on the bottom of the tank had water. So, when the truck came and filled the tanks the poor guys getting gas while filling or shortly after got water as well. Many people used to get frozen carbs including myself. Boss would deny any water being present.

Fuel pumps at filling stations have water separator type filters. Years ago before all the modern additives we would get chunks of ice in our tanks just from the condensation from parking inside overnight when it was really cold.

RMK is right about plugged filters & slow pumps. grrr
