wow..I never even though about that. Thanks for sharing, Jim

good luck with those lawsuits (adding the thermostats at the pump)!
I highly doubt the Oil companies are going to willingly put back Billions into the consumers pockets...

who knew they were selling us marshmallows.

Something I never even thought of. It would be interesting to see exactly how much of a difference the temperature makes.

i read something along those lines few yrs back, and btw, got some gas last nite at 1am

every penny counts, so why not....

but its funny, gas prices by my house and by my GFs house are veryyyy different, as much as .30, and i only live 20 mins away

so i always fill up by my house

Smart Houstonians don't wash our cars at spray car washes after dusk or fill up with gas after about 9:30 pm... too many bandits and thugs out after dark around here.

It's become really dangerous since all the impoverished Katrina victims were bussed into town and left here to scavenge for themselves.

Every single night the news reports someone getting carjacked and killed or stabbed by being on the street late at night pumping fuel on one of our major freeways, even near high dollar neighborhoods.

I think I'll start pumping my gas at 7 am when it's still cool so as to keep myself safe and get a quarter gallon more for no extra charge.

Actually, we're overcrowded here and this is my organic attempt to run off would-be move-ins! Besides, the tourism board knows all about our skyrocketing murder rates. I heard rumors of making a new marketing byline for Houston.

Houston: We've got it all:

"A great place to die. Just ask most anyone if they're still alive."
"Our heat and humidity will completely eliminate purgatory in the afterlife as 'time served' "
"Soaring crime and property taxes, not to mention some of the most poorly paved roads in the nation! What more could you ask for?"

Gee, Randall, I really wish I had taken that job in Houston now ! You make it sound like such a great place to live

Gas is stored in underground tanks... which automatically regulates the temperature of the gas. On 100 degree days, you're not buying 100 degree gas, just like the gas isn't 0 degrees when the outside temp is 0.

From an edu website: "If you take the average yearly temperature (see Table 1) of an area, that will approximately give the constant ground temperature at about 30 feet below the surface of the ground in an area which is exposed to the sky."

In other words, if you live in the north, you get a better deal, year-round. If you live in the warmer south, you don't do as well. But there's probably little actual difference from month to month in the same area... at least not as much as that article leads you to believe. And especially not day to day, as the earth many feet down from the surface simply can't react that fast.

Hi,

Yes, but the Tanks are Vented and so pull in Ambient Temperature Air to offset the Gas which is pumped out. How much difference this makes probably depends on the Air Temp, how full the Tank is, etc...

Happy Motoring!... Jim'99

Filling up in the morning!

Of course... then that newly introduced air is quickly warmed/cooled by the far greater mass of gas/metal/air that is already at the underground temp.

The point is that it's not a huge temperature swing, but rather just a few degrees, and it moves very slowly over weeks/months, not over a few hours.

I'm sure there is a minor difference in the quantity I get when I purchase gas in January as opposed to July, but not when the air temp falls 20 degrees for just 4 or 5 hours or even a few days, and the underground temp hasn't changed.

But hey, if it makes you feel good, then do it!
