TIPS ON PUMPING GAS

 

I don't know what you guys are paying for gasoline.... but here in California we are also paying higher, up to $3.75 per gallon. But my line of work is in petroleum for about 31 years now, so here are some tricks to get more of your money's worth for every gallon.

 

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 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 other 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.

i knew about the temperature but not the other tips... good effort whoever wrote that!

 

watched a documentary the other day bout petrol (or gasoline) in america and found out all companies buy their petrol in 'time' in the delivery pumps and all get the same fuel therefore. it's only after this that seperates the fuel from each 'manufacturer'! don't know bout this country, but in the usa... each companies petrol is pretty much the same!

 

my american mate also told me that the average octane rating out there is 84... and premium is like 87 ron... how shit is that!

i dont think most of our pumps have the vapour return jobbie, its something the government want to implement, but i suspect it owuld only be on the newest pumps... at the moment those vapours hes on about just get blown away by the wind..

 

the one about not filling up while the main tank is being filled by the tanker is true- underground tanks have water in them (condensation) and it gets sturred up- you then get it in your tank and a crappy running engine.. its happened a few times to me and people i know (mostly diesels though). trouble is the water takes time to settle- could even be an hour or so before your not at risk.

 

unfortunately the tricks hes on about will only pay off over the long term, and how many people will be able to stick to it?

 

good on him though.
