Tips on Pumping Gas (VERY IMPORTANT INFO)

I don't know what you guys are paying for gasoline.... but here inCalifornia we are also paying higher, up to $3.50 per gallon.But my line of work is in petroleum for about 31 years now, so here are sometricks to get more of your money's worth for every gallon..

Here at the Kinder Morgan Pipeline where I work in San Jose , CA wedeliver 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 andpremium grades.We have 34-storage tanks here with a total capacity of16,800,000 gallons.

Only buy or fill up your car or truck in the early morning when theground temperature is still cold.Remember that all service stationshave 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 andthe temperature of the gasoline, diesel and jet fuel, ethanol and otherpetroleum 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 afast 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 onlow 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 other liquid that goes to your tankbecomes vapor.Those vapors are being sucked up and back into theunderground 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 HALFFULL or HALF EMPTY.The reason for this is, the more gas you have inyour 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 andthe 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 storagetanks when you stop to buy gas, DO NOT fill up--most likely the gasolineis being stirred up as the gas is being delivered, and you might pickup some of the dirt that normally settles on the bottom. Hope this will help you get the most value for your money.
