Check the Petrol Nozzle Latch?

Dear Reader,

You may have heard that by letting the petrol fill your car more slowly, you will get more petrol. This means pressing the nozzle trigger halfway, instead of all the way. For those petrol nozzles with latches (usually three) you are able to latch the trigger so that the petrol can flow into your car engine even while you are not tending to the nozzle.

Some people complain that having latches on petrol nozzles poses a risk, in that the latch may become stuck. As a result, once the petrol nozzle is removed from the petrol pump, petrol flows immediately, uncontrolled. Even though the latches are required in some states, people have recommended removing the latches for prevention of problems like the type mentioned. (For example, see this article.)

Many writers suggest that we should use the first lever for the latch, i.e. the minimum to keep the petrol nozzle flowing. This reduces the flow of the petrol and theoretically gives you more petrol.

My complaint is that in some petrol stations, the first lever of the petrol nozzle latch is removed, so that you will latch it at the second lever. (There are only three levers). This means that you will be letting petrol flow at a faster rate, thereby giving you less petrol thank if you were to hold the petrol nozzle trigger open by your own efforts. Using the second lever to latch the petrol nozzle will cause the user to receive less petrol...

Please, leave me a message if you think that it's incorrect. :) I'd love to be informed that I'm incorrect.
