Does this make sense?

Do not Pump Full Tank of Petrol.......

READ THE REASONS -- DO NOT DONATE FUEL
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.
 
Hi

the basic message is don't overfill your tank, especially if it is a petrol car (petrol expands more)

It is potentially dangerous especially in hot weather.

You are also likely to lose sone fuel when cornering with a conpletely full tank.

The rest is conpletely OTT in my view and was probably sent to you as an email (a SPAM email too)

I have been filling up for over 45 years (never overfilled but to the first or second click)
if you fill up when you get to half a tank you are carrying more weight than necessary. You are akso doubling the number of visits to the fuel station.
Also by never running it to near empty any sludge and muck is building up and the one time you do get to the bottom of the tank you will suck up years of crud.

The above message looks like the type that are sent via email and are usually scam messages.

So Josall i think you have received an email with the above message in it and have believed it to be honest and helpful advice.

Please don't forward the email to any of your friends, that is what they want you to do.

I know you are just trying to help, but in this case i really believe that you have been a victim of a scam email.

A bit melodramatic Stephen? :rolleyes:

An interesting post and the science sound logical. On an individual basis I'd wager there's little impact on the advice given. On a global scale probably a significant matter but we could equate that to everyone handing their penny jars ( doesn't everyone have one ) into charity on the same day.

With my work car I have a half tank and fill up policy. As I use the car for response to emergencies and have no idea where I might be sent I'd not ever want to be caught with low fuel in the middle of nowhere. It happened to me once in the Galloway countryside and I vowed never again.

Funny though. My wife has a knack of leaving the A2 on the low fuel claxon till I drive the car and fill up. Smart wily lady :eek:
 
Thanks Steve, you may be right I copied this from a social net work site and deleted some from the end of the post and have now included the full post.

The original site appears to be, LE Journal.

To have an impact, we need to reach literally millions of Petrol 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?

Hi Josall

yes, these emails ate meant to spread everywhere.

The information is based on logic but it is meant to scare people enough to make you want to spread the message.
