Filling up at half full also helps with your fuel pump, keeping the pump submerged in gasoline actually helps the pump stay cool and have a longer longevity.

Thanks for the other Tips.

That was true a long time ago, but not today.
These days fuel pump is cooled and lubricated by the fuel that goes through the pump, not the fuel that's around the pump. Many cars have pumps external to the gas tank. As long as you don't run your pump dry, you're fine.

just drive to oregon & let them do it as they are all trained professionals (illegal to pump your own gas in oregon)

FF Drifter · 03-21-08, 06:13 PM

Found out the hard way it's illegal to pump your own gas in New Jersey too. I believe Oregon/New Jersey are the only states. Good tips =)

great post

This is a repost from earlier this week. After much discussion and further web research it was determined that some of these tips would give minor improvements, and others may be false. Here is more info from the previous post....Fuel Mileage Improvement

Not completely true, while i attended WyoTech I ran a test comparing 2 walbro 255 pumps from the g1 legends. The one that i filled up when it was 1/5 empty ran dead at almost 10,000 hours earlier

i need tips on how to pump gas outta other cars ...

^____^ save money !

WRONG. This was true a long time ago but with the advent of modern electronic pumps it is no longer accurate.

Quote:

Gasoline pumps compensate for density variation that occurs due to temperature, and in doing so, they measure the amount (mass) of gasoline dispensed.

Quote:

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 vapors that are created while you are pumping. All hoses at the pump have a vapor return. If you are pumping on the fast rate, some of the liquid that goes to your tank becomes vapor. Those vapors are being sucked up and back into the underground storage tank so you're getting less worth for your money.

WRONG. Not all pumps have a vapor return. I've seen many more in California and the Northern States, but never have I seen one in North Carolina. Even then what do you think has more surface area and more able to flash off to vapor, the small amount of fluid running down the filler neck or the surface area of the entire fuel tank. Even if those vapors were being sucked up and back out, the more time you have the cap off the fuel tank (by pumping slowly) the more time the large surface area of the fuel in the tank has to vaporize.

I'm not even remotely saying that this vapor theory is worth anything, I'm just refuting the statement and the logic.

Quote:

One of the most important tips is to fill up when your gas tank is HALF FULL. The reason for this is, the more gas you have in your tank the less air occupying its empty space. Gasoline evaporates faster than you can imagine.

WRONG. Modern cars have evaporative control systems and are sealed except when the OBDII system decides to purge the vapor from the tank. Where would that gasoline vapor evaporate to? If it's sealed in the tank... I think it'll stay in there. I will admit that on a hot day with a nearly empty tank you'll get a hiss when you open the cap...

But that means that the vapor isn't escaping unless you loosen the filler cap.

Quote:

Unlike service stations, here where I work, every truck that we load is temperature compensated so that every gallon is actually the exact amount.

WRONG. See above. All new pumps for some time now have been required to be electronic and fill at a corrected volume to ensure the correct mass of 1 gal is dispensed at any given time.

Quote:

Another reminder, if there is a gasoline truck pumping into the storage tanks when you stop to buy gas, DO NOT fill up--most likely the gasoline is being stirred up as the gas is being delivered, and you might pick up some of the dirt that normally settles on the bottom.

This is the only even remotely helpful thing in this whole post. They do have filters on the pumps themselves, but it is true, if there is a worst time for filling up is while the gas stations pumps are being topped up.

Quote:

Hope this will help you get the most value for your money.

Nah. Next time you get an email forward do a little research before just dropping it on us.

Next we'll see the "don't everybody don't buy gas one day and all the oil companies will go bankrupt." Suuuuure they will. Shell oil alone is making $75 million dollars a day in PROFIT (as of January 2008). They profited $27.5 Billion dollars last year...and that's just one oil company.

That's not a statistically relevant sample. What if one pump was simply defective? How do you account for potential quality/ build variation?
Time to go back to WyoTech.
