Gas/petrol filling tips

  1. Fill up your car or truck in the morning when the temperature is still cool. Remember that all service stations have their storage tanks buried below ground; and the colder the ground, the denser the gasoline. When it gets warmer gasoline expands, so if you’re filling up in the afternoon or in the evening, what should be a gallon is not exactly a gallon. In the petroleum business, the specific gravity and temperature of the fuel (gasoline, diesel, jet fuel, ethanol and other petroleum products) are significant. Every truckload that we load is temperature- compensated so that the indicated gallonage is actually the amount pumped. A one-degree rise in temperature is a big deal for businesses, but service stations don’t have temperature compensation at their pumps.

  2. If a tanker truck is filling the station’s tank at the time you want to buy gas, do not fill up; most likely dirt and sludge in the tank is being stirred up when gas is being delivered, and you might be transferring that dirt from the bottom of their tank into your car’s tank.

  3. Fill up when your gas tank is half-full (or half-empty), because the more gas you have in your tank the less air there is and gasoline evaporates rapidly, especially when it’s warm. (Gasoline storage tanks have an internal floating ‘roof’ membrane to act as a barrier between the gas and the atmosphere, thereby minimizing evaporation) .

  4. If you look at the trigger you’ll see that it has three delivery settings: slow, medium and high. When you’re filling up do not squeeze the trigger of the nozzle to the high setting. You should be pumping at the slow setting, thereby minimizing vapors created while you are pumping. Hoses at the pump are corrugated; the corrugations act as a return path for vapor recovery from gas that already has been metered. If you are pumping at the high setting, the agitated gasoline contains more vapor, which is being sucked back into th e underground tank. so you’re getting less gas for your money.

Hope this will help ease your ‘pain at the pump’

Wow…Nice…Really helpful

very useful. but I don’t think much of us will follow the guidelines as when the fuel is empty, we just fill it up and go. As for guideline no.4, I’ve actually tried it, but get a housewife/auntie who has nothing to do at home to fill up your tank, or a busy person like me won’t have the time to wait for it to slowly fill up.

Thanks for the tips.

On point 4…I thought if you fill slowly more petrol evaporates,but now I know its not.

I heard from my friend,if you smell strong petrol smell while filling up,there is possiblity there may be leakage in the pipe or the nozzle,you will loose petrol…Is this true?

thanks for the idea… point 1 & 4 i usually practice… i will buy the gas at the early morning when i on my way to work… is will take some time to fill up with the slow delivery, but at the morning… no wrong to relax ma… even i m not housewife/auntie… :P:P

HI Guys

Another good idea. Drive across the border and fill it up full-tank. Have been informed that its many times cheaper

:slight_smile:

well…i had been try b4 this trick long time ago , i think is since last two years ago. all i have to say is TRUE!!
last time when i pump in the fuel i will press as fast as i can. my car full tank is $95 and can run about 350++km.
after i know the trick then i try to use it and it really works!! it will give me more KiloMeter! now i filling same $95 for full tank but i will get around 410++km. it mean i will get extra more about 60km.
let say i pump fuel one month is 4 times = 60km x 4times = 240km x 24months = 5,760km <<----this is what i earning Kilometer for two years. heheheee…hope u guys can try it. it will no harm to u but it will let get a little benefit to u. dont look down those just little km as like malay guys say “sikit sikit lama lama jadi Bukit” hahahaaaa…c u guys!

tip 1 and tip 4 are extremely useful…

Very very useful. I’ll make a mental note to try it on my next fill up.

it wont take u too long time just about 5mins to fill in $95 for full tank. try to fill in night time. :stuck_out_tongue:

Thanks for the tips…
