Oil Companies Are Using a Simple Trick to Bilk Consumers out of Billions
Hello -
Here's an interesting article that we have talked about before : Oil Companies Are Using a Simple Trick to Bilk Consumers out of Billions - August 14, 2007. https://alternet.org/story/59593/ Quote:

Okay, so, hypothetically, every gas station is required to install some sort of temperature compensator. The cost for that is going to be ________... Anyone? Yes, passed on to the customer, that's right. And then in the afternoon someone might get one percent more gas, and who is going to pay for that? the customer or the oil company? Correct, the customer. So, now everyone has a temperature compensated gauge, and customers pay more for gas. Who won? Not the customer. Not the oil company. I guess the compensator manufacturers and their employees win. So if you want to help them out, push for legislation requiring temperature compensation. Otherwise, fill up in the morning and really stick it to the oil companies...

I'm in Oil Refinery. But I'm not in that sales or shipping/loading dept. I know there was a chart which was temperature compensated liquid density, it is used when a tank car is loading gasoline from the refinery. I believe many refineries turned into digital control system.
I guess the refinery and the gas station use the temperature compensation. But I don't know the gas station facility what they are doing. If required, it is not that expensive. BTW, I do early in the morning. |
As a side note, here in Houston/Galveston, they have ads on the radio asking people to gas up in the afternoon, so that VOC emissions due to fueling are reduced in the morning, which helps reduce ozone generation during the day.

Reduce in the morning and increase in the afternoon !!!!!
If that is true, the overall will be increased because of higher vapor pressure at higher temperature. As far as I know, there is not such ad. in LA. |
I stil think this is all a hoax. The tanks are huge aren't they? In the range of thousands of gallons. They are also underground, kept at 55F constantly by the insulation of the earth. So maybe it has some time to warm up when it's in the tube, but that's at most a gallon. So if one gallon is 50% warmer which expands the gas a percent or two, that's almost negligable.

There could be some volume change. For example, one of common gasoline component N-Pentane(NC5) will have 38.676 lb/ft^3 at 80 deg F and 39.359 at 60 deg F. There is 1.8 % volume change over the 20 deg F change.
I have to consider the cooling effect of the ground as well. 80 deg F gasoline may not be practical number, but theoretically possible. |
Anything stored in the ground is going to be roughly 55F
