說的是油槍自動跳起的時候,其實有部分油倒流回去了,但這部分是已經付過錢的了。

有興趣的,看一下吧。
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.

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!!!

好在每次都沒有加滿

除非有很好的deal, 或者很明確預期未來多少天要漲價,否則不加滿

都是加滿的

i never get full tank..... the car is lighter...

這點油沒多少吧?

+1 沒想過這個問題

再繞回來加油也是要消耗油量.

偽科學。

灌滿自動停泵,與你主動停泵,是一樣的。

剛剛加滿的人路過。
