>From a friend:
i used to work in this business doing the same thing this guy does, loading and unloading millions of gallons of tanker and barge products. all the consumer-end pumps are accurately temperature compensated nowadays, so it doesn't matter when you fill up - morning, evening, winter, summer. there's little to no difference. very accurate temperature compensation to the consumer, but it's not compensated for the consumer benefit but for the government tax, to make sure consumers don't come out ahead. the pumps are frequently calibrated at every gas station in the country by certified technicians and no one else - guys that go around doing nothing but this for a living. tank bladders are only used on alcohols, not petroleum (at least not that i've ever heard of), and only because alcohol fumes are so dangerous they must be blanketed to prevent even a static spark from igniting the product. nitrogen blankets are as common as mechanical blankets, but it's for safety, not economy. it was determined by the people i worked for that you could fill up anytime anywhere and expect to get an accurate price per gallon, except on those rare occasions when the pump was out of calibration, which wouldn't be for long and wouldn't amount to much. you can have full confidence a gallon at the pump is what you pay for. bob No virus found in this outgoing message.
