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 minimising 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 minimises 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.

My take!

Mkuu ninakubaliana na mwandishi kwa points zote kama nilivyozighlight hapo juu. Tatizo liko kwetu TZ na haswa Bongo ambako ndiko kuna watumiaji wengi wa bidhaa hii.
1. Kwa mitaa ya Bongo, hali ya hewa iwe asubuhi au jioni bado ni joto, nadhani kwa hali ya hewa wauzaji wanatupata sana!

2. Kwa utaratibu wa TZ petrol stations nyingi kama sio zote kuna utaratibu wa kuhudumiwa. Mteja hana mamlaka ya kugusa mkono wa ile pampu kwa hiyo huwezi sema ati weka kwenye "low mode" jibu utakalopewa nadhani utaambiwa unawaletea watu usiku! Anyway sijajaribu labda ntaanza sasa baada ya kusoma huu ujumbe.

3. Kujaza mafuta wakati tank liko nusu ni kweli ni kitu ambacho nime-experience binafsi. Petrol inapokuwa ndogo inaisha haraka sana. Ila ukijaza mafuta mengi inatumia muda kuisha! Tatizo kwa walio wengi ni uchumi!!!

4. Hili la mwisho ni sawia kabisa! Wakati wanashusha mzigo na wewe unajaza utaishia kupata takataka na mwisho kuua filter na hata injini ya gari lako bila sababu!!!

Hili ni somo maridhawa sana!

asante saaaaana.
kuanzia leo ntakuwa nazingatia yafuatayo:
1 ntanunua petroli usiku sana,wakati joto hamna
2-kwa kuwa bongo lazima uwekewe petroli ntakuwa sinunui in rush hrs-ili iwe on a slow mode
3-ntabeba galons za 20ltrs ,najaza then ndo naweka ktk gari
 
Petrol storage tanks have an internal floating roof. This roof serves as zero clearance between the Petrol and the atmosphere, so it minimises the evaporation.
Kama kuna internal floating roof which "serves as zero clearance between Petrol and atmosphere" ina maana at any given moment hakuna empty space juu ya mafuta kwa sababu roof ya tank inateremka chini na level ya mafuta, au kwa maneno mengine, wakati wote, hata kama una robo tank, tank bado ni kama limejaa! Hiyo ndio maana yake ukiniambia "roof ya tank ina float"!

Sasa pointi ya kusema ni bora kujaza mafuta mengi kuzuia evaporation inakuwa mute, inakufa hapo hapo. Kunakuwa hakuna faida yake. Eleza tena.
