You drive?

Assalamualaikum wbt.

You drive? I’ll be driving back too…soon. After 4 years with license, finally abah granted the permission for me to drive after a loooong nag from my mum and me. Mak, “kalau anis drive, dia boleh hantaq ami pi skolah, ambik ami balik awai sket, dia buleh pi pasaq, kalau mak kursus abah tak payah nak balik awai ambik ami...” hehe. finally, abah conceded.

Oil price. Not a good stuff. Tetapi hidup mesti diteruskan. Kepada kawan-kawan PMC yang baru saja mematikan angan-angan berkereta bila balik tahun depan, don’t be. Jimat-jimat mesti.

Found this tips from a friend. Credits to her. Physics and chemistry is a lot fun, yeah?
  1)  Only  buy or fill up your car or bakkie 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 fuel, 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..
     2)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. In  slow  mode you should be pumping on low speed, 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.
  3) One of the most  important tips is to fill up when your tank is HALF FULL. The reason for this  is, the more fuel you have in your tank the less air occupying its empty  space.  petrol evaporates faster than you can imagine. Petroleum 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.

From now on, i must be thinking like Michael Scoffield;-)
