A few interesting suggestions:
Only buy or fill up your car in the early morning when the ground temperature is still cold.
In the petroleum business, the specific gravity and the temperature of the petrol, diesel, jet fuel, ethanol and other petroleum products play an important role. A one degree rise in temperature is a big deal in the business but the Service Stations do not have temperature compensation at the pumps. All Service Stations have their storage tanks buried beneath the ground. The colder the ground the denser the fuel, when it gets warmer petrol expands, so buying in the afternoon or evening your gallon is not exactly a gallon. This time of the year where I live and most of the people reading this live we don’t have to worry about it getting warm in the afternoon.
When you are 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 you are pumping on the fast
rate, some of the liquid that goes into 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 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 petrol and the atmosphere, so it minimizes the evaporation.
