Useful tips on filling petrol in cars/bikes

 

Tips to save your petrol :

 

1. 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.

 

2. 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.

 

3. 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.

 

4. 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.
