Getting Gas

[accordoholic]

I was just getting gas for my car and my friend said it is bad to pump gas because the gas truck was there pumping gas at the same time. Said something like you get all the bad gas or something.

It all depends on where you go/how busy they are. Most pumps will tell you the dates.

i heard its best to get gas late at night or early morning when its the coolest out cause its denser then. but dunno about the truck thing.

i don't think it makes a difference. and if it does, it probably won't be anything noticeable. hence, not even worth thinking about.

You get more for your money, but not much, so it really doesn't matter when you get it, unless you're OCD.

The myth is that there could be air bubbles that are caused from the filling from the truck to the underground tanks that could get in the engine and cause damage. Rule of thumb is just try to catch is before of to wait until after the truck is done so that the old and new gas is mixed. It doesn't really matter just preferences.

air bubbles wouldnt matter at all those tanks arent air proof and when u pump the gas into your car if you had it its just gonna sit on in the top of your tank lol, that has nothing to do with it

Your friend is wrong.
It doesn't matter because the truck hooks up to the underground tanks which are pressurized, and it is then distributed to your car.
Not just straight from the truck.

haha you get the same gas that hes pumping in, it doesnt matter.

if you're paranoid then figure out the schedule when the gas truck comes in, and get there after to fill up with fresh fuel.

The only issue I can see is that the truck is stirring up the gas in the underground tank as it fills it. That means any sediment that was at the bottom is now floating. When the truck is not there, that sediment remains undisturbed.

If you're going to a quality station, they're less likely to have a significant amount of sediment... so I wouldn't worry. If you went to some crappy cheap-o place with the same two foreign guys running it 24/7, THEN you might have reason to worry!


MOST stations should filter their gas at the pump anyway. There are some that are supposedly better than others (Sunoco and Exxon, I think I once heard? Never confirmed that). If any don't, it's probably the cheapie no-name ones.

Newer electronic pumps are temperature compensated, so temp doesn't matter.

Not sure what you mean by "airproof", but all pumps have air eliminators, so air is NOT metered.

always fillin with mobil..keepin it safe.

UST's are not pressurised. When testing them after installation, we can only test them to 5psi, which isn't nearly enough to provide the flow required for a busy station.

Gas stations are either a pressure system, with pumps in the tank pressurising the lines, or a vacuum system, with suction pumps in the dispensers.

All pumps have internal filters, and they don't have a bypass. Slow flow usually means a clogged filter, or a tripped leak detector on a pressure system.
