Tips to save your fuel:
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, fuel 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 fuel play an important role. A 1-degree rise in temperature is significant 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 stages: low, middle, and high. In slow mode, you should be pumping at 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 at 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. Fuel evaporates faster than you can imagine. Fuel storage tanks have an internal floating roof. This roof serves as zero clearance between the fuel and the atmosphere, minimizing evaporation.
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 fuel is being stirred up as it 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.
