Gas Pumping Tips [MERGED]

[chua_riwap]

I received these tips from my email (ewan ko kung meron na kayo). But anyway, I did a search on the Tsikot threads, and found none of the same topic, so I decided to share this with you, guys. The email reads "as is" and I just did a cut & paste on the item. However, I intentionally deleted the email sender.

Gas Pumping Tips

.......from someone in the Petroleum pipeline business!!


I've been in petroleum pipeline business for about 31 years, currently working for the Kinder-Morgan Pipeline here in San Jose, CA. We deliver about 4 million gallons in a 24-hour period from the pipe line; one day it's diesel, the next day it's jet fuel and gasoline. We have 34 storage tanks here with a total capacity of 16,800,000 gallons. Here are some tricks to help you get your money's worth.

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'

It's the first time that I heard/read #3... will check that out... from my observation there seems to be some truth to that.

Thanks, il remember these tips the next tym i fill er up!

Does this apply to all types of fuel?

Thanks for sharing. They all seem logical to me....

I'm practicing item #1, but not really going in for full tank. Half, yes.

my brother who works at Shell USA mentioned the #1 and 2. I do always follow the #3. what makes me think is about the #4. Do we have different trigger settings here? Hope so. Another is the pump calibration sticker authenticity.

I know #1. but do not follow the advise. I often gas up early evening when I go home.

Natutunan ko ang #2 dito sa forum.

#3 - I do not know this. I get fuel when the meter says less than 1/4.

#4 - we do not pump our own gas, so I think there is nothing I can do about this.

[red07]

I practice #1. Morning ako palagi nagpapa gas.

#2 Dapat pala maging observant ako, ni minsan hindi ko napansin na nag a-unload ng gaso yung mga tanker na kasabay ko sa gasolinahan.

#3 Nagpapagas ako pag malapit na sa empty line, pero hindi ko na hinintay na umilaw yung gas gauge.

Just like what meledson said, hindi applicable yung #4 sa atin.

Thanks for the tips.

nice post sir

totoo po iyan
