I've Bolded the tips. read and execute.


I'm not a scientist so I can't verify the total accuracy, but this makes sense and it helps save on gas, why not try it.


I don't know what you guys are paying for gasoline.... but here in Canada we are paying up to 132.5 at gas stations (means $1.325/Litre - $5.02/Gallon), so here are some tricks to get more of your money's worth for every Litre/Gallon:

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.

A 1-degree rise in temperature is a big deal. 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.

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.

Sorry for all that reading but I hope i at least helped the people that read all the way through

It's all true

ive been doing this for a couple months now and ive been filling up less at the pump and getting more milage as well... but it is a little pain to pump slowly LOL

cranemaster

I put $20 at a time in, so im car is fast - and gets better mileage.

Been that way for 4 years... ahahah. Oh well.

Good write up just the same, if I get a Pruis I will definitely follow these rules.

hmm good info. thanks!

jsscooby

have seen this before and it dose make sense.

good stuff. another thing is to move the hose around a good amount and hold it up and look like a jackass haha because a good amount of gas stays in the hose.

denlou

All pumps are corrected to 15*c BY LAW (In Canada anyway)

Yes they do, read above...

Except that's all negated by the fact it's a closed system, vehicles can't vent fuel vapours into the air, emissions law...

You have heard of a fuel filter right? Gasoline stations have them too...

Hey i've did the lifting the hose up above ur head and found out that u shouldn't do it when u have someone with cause they will tape it with there phone. Looked like a dip ****

BPacak

its worth it haha. i work at a gas station and when we change a hose gotta get a bucket and drain the gas out and there is a good amount haha.

denlou

With the exception of MAYBE the last one, there really is no argument to had...

XxSNAKExX

im not even gonna spend my time arguing with your everypoint...

from one stand point u r correct, from several others your wrong lol

Tank Temperature doesn't fluctuate much if at all from morning to afternoon.

06SS ALL DAY

repost from like 6 years ago lol

plaxton

did you know that the ground around the pumps never goes above 15C, thats why the companys base there prices off fuel flow at 15 instead of another number. atleast where i live it never goes above 15.

at least it'll be a good reminder

I don't think that you get any more gas out of the hose once it shuts off at the nozzle.

BPacak

oh you do try it out haha

denlou

shhhh... There's no place for logic here. For some reason people here think that when let go of the handle it closes a valve inside the pump. Carefull, telling them that they're closing the valve on the handle with the lever on the handle might cause their brains to implode.

You do realize in ground temp stays fairly constant, and all tanks are below the frost line (which is pretty deep in canada I'm sure) there is more mass per unit of volume in the ground vs air, therefore air takes less energy to change temp (pick up a physics or chem book). The amount of energy to change soil temps is much higher, the surface my change temp readily, but dig 6in (or like 12cm) and the temp will drop. Time of day has no difference (and liquid volume is not that temp dependent, small changes less than 1percent)
