is it true you get more gas when the ground is cold?

Since most pumps dispense based on volume, one effectively gets "more" gasoline when the gasoline is cold. Most stations store gasoline in underground tank and, given enough time since last filled, the fuel will be the same temperature as the ground at the same depth. The ground at that depth does not change very much with the season and varies very slowly. You may effectively get a small amount more gasoline in the middle of winter compared to the middle of the summer but you will not see much difference between the middle of the day and the middle of the night.
tattoo666TX Champion Author Texas Posts:2,567 Points:344,480 Joined:May 2011	Message Posted: Dec 14, 2011 7:54:06 AM Ignore tattoo666TX Report Abuse Again, what does fuel expansion have to do with this? It was not asked if it makes a difference if you fuel in cold weather. It was a question about the temp of the road surface, which has nothing to do with how mush fuel you have or weather it expands or not, which is a moot point anyway being that all newer vehicles have fuel injection. So being that the question was about the temp of the road surface, when it gets colder there is more rolling resistance. Same as when the road is wet or has anything else on it. There is more rolling resistance which means lower mileage. Now as for fuel expansion. If a molecule of fuel expands or contracts due to temp, it is still just one molecule of fuel. It does not magically change to 2 or 3 molecules. When it contracts it does not turn into less then 1 molecule. So being that fuel injection basically vaporizes molecules of fuel for better burning, and the computer monitors and adjust to keep it at a constant rate, the temp of the fuel has nothing to do with mileage.

If you fill when it is cold and then drive while it is cold, no difference. no expansion.
CactusBobs Champion Author Phoenix Posts:2,721 Points:485,775 Joined:Jun 2010	Message Posted: Dec 14, 2011 2:12:04 AM Ignore CactusBobs Report Abuse Years ago , when gas caps where vented . If you filled your car and drove right home , the next day when the Arizona sun would warm up the cars gas tank , it would overflow .......So gas does expand when it gets hot , so you have more when it is ,hot than when it was pumped out of the cold ground ......did any of this matter ... not at all , other than making a mess, and the yard smelling like gas , only a cup or two was lost , at the most .

dontuknowOH Champion Author Ohio Posts:2,097 Points:36,545 Joined:Aug 2009	Message Posted: Dec 13, 2011 8:47:28 PM Ignore dontuknowOH Report Abuse I usually get more gas then because of the posibility of a snow and more weight for a rear wheel drive, gives better traction for pick-ups. Snow or wet pavement does make an unloaded truck a bit unstable at times,also a full tank will weigh more because of the larger size 33 gal.+ When the ground is cold,often the air is cold extra gas doesn't evaporate as quick because of that so.... LOL

For Gods sake people think an issue through for once in your life. Kind of like that "Hope and Change" you fell for without asking what he planned on changing.
tattoo666TX Champion Author Texas Posts:2,567 Points:344,480 Joined:May 2011	Message Posted: Dec 11, 2011 1:11:20 AM Ignore tattoo666TX Report Abuse Has nothing to do with weather gas expands or not at cold temps. Why do you think people put cold air intakes on? Nothing to do with the gas, all about the air. As far as the temp of the road, colder surface temp on the roads, or wet roads increase rolling resistance, which translates to lower mileage.

WEPSMAN Champion Author South Dakota Posts:10,503 Points:2,021,750 Joined:Mar 2005	Message Posted: Dec 10, 2011 8:22:13 AM Ignore WEPSMAN Report Abuse There is a little merit to this, but not something to bank on. Gas does condense when cold and expand when warm. When storage tanks are under ground, the temp is not that much different. A majority of people would never know the diffeence since it is so minute.

1OILMAN Champion Author Alabama Posts:2,069 Points:155,610 Joined:Mar 2011	Message Posted: May 25, 2011 6:43:56 PM Ignore 1OILMAN Report Abuse Pour some gas in a jar, mark the level. Put in your refrigerator overnight. Take jar out and check the level. Did the level change? Now throw out all your refrigerator contents. The temperature in UNDERGROUND tanks stays very close to the same temperature at all times. So the answer is NO.
