Just recieved this in an e-mail, I wonder if there is any merit to this?

Please feel free too add comments on what you think about this:

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 t emperature 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. In slow mode 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 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 wh en 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 d elivered, and you might pick up some
of the dirt that normally settles on the bottom.

It's probably mostly accurate, but what they fail to mention is that even if you follow every single one of these it will probably only net you about .0000000001 gallons of gas.

how much can one REALLY save by following these rules... a dollar for all the extra effort. I will pay an extra buck just to get the hell out of there in less time...

Tip - Don't buy fuel in Switzerland (cost us 93 frank today to fill my tank with diesel...that is about $80 USD)

That's all I got.

i think gulf gas sucks...

Its been passed on with slight changes.. It wont do any good following that the sludge in the gas tank is over played it doesnt matter anyways since you have a fuel filter.. But if you want to save gas check your tire pressure.

+1...and take all that excess junk out of your trunk (pun intended and meant both literally, and figuratively...btw..I can say that b/c I am a fat ass)

[iPodAddict]

Most gasoline stations use corrected temperatures for their storage of gas.

I.e. 15 degrees Celcius is about the norm.


If you go to a ghetto/run-down station, you're asking for trouble I'd say lol.

Go to Costco.

Yea if you live close.. I worked out that driving to costco and back would use a little over a gallon of gas for me. Dividing that out over the 16 gallons of gas let assume costcos gas is $2.89 a gal and the gas station down the street is $3.00. Well I am burning a gallon to get to costco and back at $2.89 so divide that out over the 16 gallons since its really costing me $2.89 + 18 cents, which is 3.07 a gallon so it actually ends up costing more. But I cant tell you how many times I have worked this out for folks I know that have to drive even further, but it must be psychological of seeing a lower number.

Just put water in your tank and see what happens if gas costs too much...lol.

No matter what, you need gas and that's the bottom line. I love the folks that drive around looking for cheap prices...umm duh.

I like the analysis, but need quantification. One thing is for sure, the premium gas that is usually priced $0.10 + 0.10 = $0.20 more than regular gas is a better bargain at $3.00+ a gallon than a couple years ago when it was $2.00+ a gallon. (% change)

I have heard this too, not sure how true it is though.

So catch the bus or walk? Or pay loads for a taxi?

He said don't buy it, so I'm thinking steal it then...

or maybe drive to a near by country if you live near the border???

those tips are useful (except for number 1 since most stations are regulated at 15 degrees C)

but for those who live in Canada, the best idea is to sign up for a petro canada mastercard.. not only do you get the 3.5 Cent deduction/litre, but you also save an additional 2 cents with using the Mastercard.. thats a total of 5.5cents per litre.. also i like the fact that petro canada has the point system, so that after around 40 gas station stops, you get a free car wash.. normally i don't take my E90 to the carwash , but i give it to my sister, who does not really care about touchless or normal carwash systems...



But in the end, the best and most efficent way of saving gas is your driving style.. always check your tire pressure daily if possible, make sure to take out heavy items that you might not need (i take out my spare tire, since i live and work near my home, i see no point in a spare tire) , and drive within the speed limit to reduce burning extra gas.
