Fuel Pump Calibration!!!!!!

[JPW#]

I found I get the most miles with Sasol fuel, second , BP and then Shell and then the rest follows. Filling up early morning is best , u get more fuel.I also heard a rumor that it costs the gov a million rand each time , to have the pumps set.

Received the following via e-mail: TIPS ON FILLING YOUR VECHILES  (Good information) I don't know what you guys are paying for petrol.... but here in Durban we are also paying higher, up to Rxxx per litre. 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 litre. Here at the Marian Hill Pipeline where I work in Durban, we deliver about 4 million litres in a 24-hour period thru the pipeline. One day is diesel the next day is jet fuel, and petrol, LRP and Unleaded. We have 34-storage tanks here with a total capacity of 16,800,000 litres. Only buy or fill up your car or bakkie 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 fuel, when it gets warmer petrol expands, so buying in the afternoon or in the evening....your litre is not exactly a litre. In the petroleum business, the specific gravity and the temperature of the petrol, 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 vapours that are created while you are pumping. All hoses at the pump have a vapour return. If you are pumping on the fast rate, some of the liquid that goes to your tank becomes vapour. Those vapours 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 tank is HALF FULL.  The reason for this is, the more fuel you have in your tank the less air occupying its empty space. petrol evaporates faster than you can imagine. Petroleum storage tanks have an internal floating roof. This roof serves as zero clearance between the petrol 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 litre is actually the exact amount. Another reminder, if there is a fuel truck pumping into the storage tanks when you stop to buy, DO NOT fill up--most likely the petrol/diesel is being stirred up as the fuel 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.

Personally I feel that the amount of expansion / compression is so small I don't worry about it. And there is no way it can cost the government 1 mill to set the pumps as they don't own them and have nothing to do with them. They are owned by either the garage owners or the oil companies.  The government is more likely to make money every time a pump is set - from the tax on the workforce etc.

Something like half the price of petrol goes to tax. The other interesting thing that I checked this morning is that a barrel of crude oil is about $46 I think it was this morning. In 2005 the price was $49 plus minus. At the same time the petrol was R5.22 compared to R8.64 If I have it right (depends where you are).

This is also why I love my Vuka 43km/l

i think this is a query for NASA

I believe it is comming down to around R7.20 next month - given inflation over the last 3 years it sounds about right. But 10 cents difference on the up when it comes to this means huge bucks in somebodies back pocket. MuXmAn2008-11-24 06:04:44

The effect of the drop in the oil price has been negated by our Rand weakening against the Dollar, but the petrol price should drop next month again, just in time for the summer holiday. But ja, we are still paying through our teeth for fuel.

does a Prius need petrol.......

it actually needs "quite a lot" - I was stunend when I found out how much it uses!

Fill your 5 litre bottle with water and weigh it,  it should weigh 5kg. If more your bottle is bigger or your scale is out.

what about altitude and temperature?

And what does the bottle weigh,  that will also influence the weight/reading
