Default Tips on Buying Fuel

Got this sent to me today, anyone out there able to confirm, it certainly does make sense!

TIPS ON PUMPING PETROL



I don't know what you guys are paying for Petrol.... but

here in Melbourne we are paying up to $1.30 to $1.50 per litre. 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 Litre:



Here at the Shell Pipeline where I work in Melbourne, we deliver

about 4 million litres in a 24-hour period thru the pipeline.. One day

is diesel the next day is jet fuel, and Petrol, regular and premium

grades. We have 34-storage tanks here with a total capacity of

16,800,000 Litres.



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 Petrol, when it gets warmer Petrol expands, so

buying in the afternoon or in the evening....your litre is not exactly

a litre. In the petroleum business, the specific gravity and the

temperature of the Petrol, 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 Petrol

tank is HALF FULL. The reason for this is the more Petrol you have in

your tank the less air occupying its empty space. Petrololine evaporates

faster than you can imagine. Petrol storage tanks have an internal

floating roof. This roof serves as zero clearance between the Petrol 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 litre is actually the exact amount.



Another reminder, if there is a Petrol truck pumping into

the storage tanks when you stop to buy Petrol, DO NOT fill up; most

likely the Petrol is being stirred up as the Petrol is being

delivered, and you might pick up some of the dirt that normally settles

on the bottom.

I always thought the floating roof on the tanks in the refineries was to minimise the space for fumes which are a bigger risk for explosion than the fuel itself.
I like the theory on filling up in the morning.
Cheers,
Andrew.

I would have thought that underground tank temperatures wouldn't change all that much between day and night. It would depend on how deep they are. The ground above the tanks is usually shaded for most of the day at most of the service stations near me. I can understand that it would be a problem for above ground tanks for sure.

But if the fuel is delivered at one temperature, and the underground tanks equalise at another temperature, there probably would be a time when the fuel would be the coldest and most dense. Either just before or just after a delivery would be my guess without knowing the details. It's all food for thought though.

Question

Good read but where the area i fill up in is cheapest on Thursday or Friday buy over 10 cents a litre! This difference in price will not make up for any fuel temp diff etc.

Maybe you can answer how fuel can go from $1.26 to $1.39 in 12 hours.

the temp in the underground tank will rise thru the day , as for every litre of petrol pumped out to a customers car one litre of warm air is returned to the underground tank. dont know how significant this would be tho.

i would pay 10 cents a litre for the right to buy petrol at 1.39 a litre - you guys have it good.


cheers

Im prety sure that tanks are at least 2 meters undergound and the temperature variance would be minimal hence why people live underground at places like cooper pedy etc...and if you look around a petrol station you will notice venting pipes to allow air and gas flow once the air is underground it would equalise as air does not hold temps all that long. Having said all that the density difference would be measured in millilitres not litres. You will save more using your coles and woolies vouchers!
