Do not Pump Full Tank of Petrol......READ THE REASONS !!!

Recently I came across a very useful tip. I was surprised to know it but had a doubt so I talked to one of the pump technicians and he too accepted it as a fact. I think apart from providing space for the gas generated inside the petrol tank this is yet another reason why we shouldn't fill the tank to the brim. Many of us are not aware that the petrol kiosk pump has a return pipe-line (in Pink).
When the petrol tank (in the car) reaches full level, there is a mechanism to trigger off the pump latch and at the same time a return-valve is opened (at the top of the pump station) to allow excess petrol to flow back into the pump. But the return petrol has already pass through the meter, meaning you are donating the petrol back to the Oil Dealer.

Also only 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 liter is not exactly a liter. 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 vapours that are created while you are pumping. All hoses at the pump have a vapour return. If you are pumping on the fast rate, some of the liquid that goes to your tank becomes vapour. Those vapours 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. petrol 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.

hmmm 145/ltr one need to research like Neva before Sai Baba hear its still going up.

Okay

Hmmmm.. ...

The economic hardship in Nigeria makes filling up your car at full tank a golden opportunity.

This will only work in countries like South Africa and developed countries.

Really?

Just buy the damn petrol and hit the road. Which kain economy is this

I don't believe that return valve whatever, the siphon used produces a jet of petrol in one direction only.
BTW, the volumetric expansion coefficient of petrol is 0.000095 ^oC^-1 meaning that 20 litres of fuel will expand by 20*5*0.00095=0.0095Litres with a change in temperature of 5^oC. Which is not even up to 1 percent of a litre. So, fuel wouldn't expand so much in the afternoon or evening as writer claims.

Well, in a time of recession, people would find means of saving the minutest of money. This is what we call buhariconomics

Noted

I see. No wonder.

great info

I just buy 2500 dis morning . Who get money for full tank btw . I have noticed dis thing too. Sometimes 34litres -5k go almost full person tank

No be who get car, go buy full tank?




Thanks for the info anyway

I never get Moto

wow! my village people must hear this.

This is a wonderful piece #babayoutoomuch you're too much truly!!! Thanks on our behalf!

Very informative but if petrol scarcity dey we country and your motor spend two days for queue for filling/gas station this theory fit no work o

Nah U should fill up at every opportunity .
What you should not do is let your car run out of fuel.

Odi egwu

Thanks Kumar!

good one

Useful information.

this info is much needed at this time...
make i rush go inform chibuzo for Oando

This is really helpful and educative. This kinda piece should make front page not what we get to see like 95percent of the time

Great info.. Thnks

I think I will try this. I am always fond of filling up my tank. I was surprised how I spent about 75k on fuel only last month! This month only, the petrol bill is already well over 40k. I need this fuel economy now more than anything. Thanks OP.

I dunno what this indian man researched to write this... As clearly the much talked about fuel you'll save is very meagre.

But trust nigerians...nobody would oppose..you'll see how dense most people are.. They just accept anything take it as a fact and pass it on to the next person.

Do we not have objective or intellignet people? This APC and PDP thing have really rewired some peoples brain..because the thing inbetween their ears has gone rusty from lack of use.

Good information.

Since this 145lt, I have never filled my tank, highest is 3k

To achieve half tank sef no easy @ 145/litre.....abeg save your teaching till we can buy fuel @ 50/litre
