When you fill a 5 gal can in the winter with 5 gal (pump reading) the can appears to be about 3/4 full. When you do the same in the summer the can appears to be about 1 1/4 full. This is due to expansion/contraction of the liquid so you do actually get an accurate MEASURED amount of gas. This same effect is noted on your container (i gas tank) so if it expands in high temperature the volume it holds increases. The expansion of the liquids can be seen by filling a gallon jug to the top with water and the freezing it. You still only have a gallon of water but it will no longer fit in the container. Ever over fill the gas tank only to have it spill out later when it heated up?
Prior to the temperature law came into effect, used to haul fuel up Lake Winnipeg in a barge. We always filled early in the morning, and off loaded late in the afternoon. You would be surprised how much extra fuel came out of the barge... actually paid for the two day trip.
So where in your equation does the underground tank that is at a constant temp come in. Baloney my friend

Temperature compensation is necessary and common when buying fuels…
Weight is the only true measure no matter how it is sold… a gallon of fuel at 60* has a known weight and a known BTU content and at that weight it is true gallon with the same BTU content at any temp… it is the only standard of measure…
however a volume measured gallon could be much different both in weight and BTU content… so a gallon of fuel isn’t a true gallon unless it is kept at 60* or has been temperature compensated…
Propane delivery trucks for home heating are all required to have TC devices connected to their pump, and why weight is the best method of filling small cylinders of propane…
At a retail level some states may require TC on motor fuels and a number of states are considering it they don’t require it already…
I can’t imagine a bulk buyer not using some form of TC when buying their supply, even liquid asphalts are temperature compensated… since we don’t control the outside temps it is the only way to know what you are getting and that you are getting what you are paying for…

Here is a link to a report published by the House of Representatives in 2007 on the subject of expansion and contraction of gasoline and its effects on the consumer.
The report stated that no retail stations in the US were required at that time to sell fuel by weight instead of volume (as of 2007). It also confirmed that fuel is sold by weight at the wholesale level.
What about buying fuel in the dead of winter? It seems to me that we are receiving a discount on energy content when buying at that time.
Read the report as listed by Cedar Hill and/or contact your state weights & measures agency, any consumer group, google gasoline expansion. Do you really think that gasoline in an underground storage tank will stay at a constant 60 degrees when the earth around the tank is frozen solid ( i below 32'F), or coversely heated above 80'F. The top of the tank is only three feet down.In this part of the country frost goes down at least 6 feet in the winter as it does in Alaska and let me tell you that will shrink your baloney.
Fill a 5 gal container with gas, mark the level immediatley then sit it out in the sun for few hours and recheck the level. Thats where the money was on the barge!

I guess in most of Canada motor fuels have ATC pumps… is that correct??? I suppose mainly because the cooler the climate, the more beneficial it is to the seller and you had less opposition from the dealers…
My question is do they have anything on the pump stating that the pump has ATC (automatic temperature compensation)???
Yes the pumps have a prominent label stating that volumes are adjusted to 15'C. It is a sort of toss up because it depends upon the mean average temperature in your area as well as whether they have under or above ground tanks
First off, I hate the fact that fuel prices are soaring. In some cases it seems to be artificial and even pushed by the current administration. That being said here's some facts for thought.
30 day 2000 mile summer vacation.
10mpg
200gal
$3.50/gal
Total cost of fuel is $700.
10mpg
200gal
$4.00/gal
Total cost of fuel is $800.
The difference is $100 over 30 days or $3.33/day.
If my wife and I go out to eat at Texas Roadhouse (yum!) and I have my standard one or two drinks and my loaded baked potato and she just drinks water, our bill, with tip is just under $50. I have to eat regardless, so this cost is probably about $40 more than I would spend for a meal at home. I want to be fair so let's say we have steaks at home so Texas Roadhouse only costs $30 more. $100/$30 is approximately 3. Therefore if I go on vacation and skip eating out three times I've covered the extra cost of fuel. That's 3 days out of thirty and I know many people eat out every evening, in fact I'm shocked by how many do.
I refuse to let my vacations get ruined by $100. I know fuel prices impact people's daily lives and not just vacations, but I plan my vacations many months and sometimes a year or more in advance so I can adjust. I always fudge all costs but especially fuel costs due to the economy lately. My rule of thumb is about 50% more in the fuel fund than I plan on using. Any left over money gets put towards the next trip or vacation.
Someone mentioned extremely high fuel prices in parts of California. I also use Gas Buddy or gasprices.com to scout out prices prior to heading out on a trip. I will avoid places that are excessively high cost and in some cases I even plan on not getting fuel on entire segments of a trip. Often times when I go to San Diego I generally top off in Yuma, AZ and then don't buy fuel until my return. Sometimes I do buy fuel in San Diego because I'm there long enough to need it or I can get a good price at 32nd Street Naval Station...I just have to be flexible. I will never drive out of my way to save money on fuel. That simply doesn't make sense in most cases, I just look for the best deals on my intended path.
I've also learned not to buy fuel in Kearney, NE...I think they add an extra tax to pay for the over-the-interstate museum...lol. (Fuel prices are normal one mile off the interstate, which is likely true at many locations.)

in response to MaxThrust... I believe fuel prices are a hot-button issue with lots of folks, because it has an impact on our daily lives, and it is daily in our faces. We don't see the current price of green beans on a placard outside the local market, and who would drive across town to buy a few cheaper green beans? My point is similar to Max, a few cents a gallon can probably be made up somewhere else, and camping is just too much fun to abstain! So I'll eat a cheaper cut of steak or a nice burger, even, if it means I can camp another night in this wonderful land of ours, and enjoy God's MANY blessings at the same time!! Have a Great Memorial Day, Friends and say "thank you" to a vet, and remember those who gave all for our Freedom!

Yes I Believe a tank buried underground and well below the frost level will stay a constant 55 degrees. It is science not speculation.
