Here at the Kinder Morgan Pipeline where I work in San Jose , CA we deliver about 4 million gallons in a 24-hour period thru the pipeline. One day is diesel the next day is jet fuel, and gasoline, regular and premium grades. We have 34-storage tanks here with a total capacity of 16,800,000 gallons.
Only buy or fill up your car or truck in the early morning when the ground temperature is still cold. Remember that all service stations have their storage tanks buried below ground. The colder the ground the more dense the gasoline, when it gets warmer gasoline e xpands, so buying in the afternoon or in the evening....your gallon is not exactly a gallon. In the petroleum business, the specific gravity and the temperature of the gasoline, diesel and jet fuel, ethanol and other petroleum products plays an important role.
A 1-degree rise in temperature is a big deal for this business. But the service stations do not have temperature compensation at the pumps.
One of the most important tips is to fill up when your gas tank is HALF FULL or HALF EMPTY. The reason for this is, the more gas you have in your tank the less air occupying its empty space. Gasoline evaporates faster than you can imagine. Gasoline storage tanks have an internal floating roof. This roof serves as zero clearance between the gas and the atmosphere, so it minimizes the evaporation. Unlike service stations, here where I work, every truck that we load is temperature compensated so that every gallon is actually the exact amount.
Another reminder, if there is a gasoline truck pumping into the storage tanks when you stop to buy gas, DO NOT fill up--most likely the gasoline is being stirred up as the gas is being delivered, and you might pick up some f the dirt that normally settles on the bottom. Hope this will help you get the most value for your money.
WHERE TO BUY USA GAS, THIS IS VERY IMPORTANT TO KNOW. READ ON
Gas rationing in the 80's worked even though we grumbled about it. It might even be good for us! The Saudis are boycotting American goods. We should return the favor.
An interesting thought is to boycott their GAS.
Every time you fill up the car, you can avoid putting more money into the coffers of Saudi Arabia. Just buy from gas companies that don't import their oil from the Saudis.
Nothing is more frustrating than the feeling that every time I fill-up the tank, I am sending my money to people who are trying to kill me, my family, and my friends.
These companies import Middle Eastern oil:
