> TIPS ON PUMPING GAS--GOOD INFO!
>> 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 expands, 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.
>>
>> When you're filling up do not squeeze the trigger of the nozzle to
>> a fast mode. If you look you will see that the trigger has three (3)
>> stages:
>> low, middle, and high. In slow mode you should be pumping on low speed,
>> thereby minimizing the vapors that are created while you are pumping.
>> All
>> hoses at the pump have a vapor return. If you are pumping on the fast
>> rate,
>> some of the liquid that goes to your tank becomes vapor. Those vapors
>> are being sucked up and back into the underground storage tank so
>> you're
>> getting less worth for your money.
>>
>> 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 of the dirt that normally settles on the bottom.
>>
>> Hope this will help you get the most value for your money.
