Full tank vs first click

This morning the attendant filled it to the brim, even though I said he needs to fill it up.
It cost just over R800 :D
 
That's why it is there: The first click; the tank is full and there space for expansion.
Similarly: No LPG gas cylinder is filled to overflowing or until it is 'full', the ullage is allowed for expansion.
Don't overfill and be foolish, rather stay alive than save R26.00.
BTW 'ullage' is the space for expansion and the reason why any bottle isn't filled to the brim.
 
I go with first click. I see no difference in my range when throwing in more after that.

At a great cost of safety features.
For example:

You're the guy , you've filled up to the brim, just before the price increase. Lekker feeling nê?
After you pull out from the pumps you hit the traffic and some beggar comes begging at the traffic lights. He has a cigarette butt in his hand.
Some fuel vapour or fuel overflow stems from your car's fuel cap because you did a sharp left.

Goodbye Meraai!!!!!!!!!!!


Just why do think that that fuel pumps have a trigger off on the nozzle????

Yeah, not gonna happen. The fuel cap is an airtight seal.
Also, a cigarette butt will not ignite petrol.

So much wrong with this post:

1. A cigarette butt cannot ignite fuel vapor or even wet fuel.
2. The trigger off nozzle is to prevent human error when filling up your tank.
 
The fuel cap will not contain a pressue build up of a fuel tank. There has to be a pressure release valve otherwise the tank will explode.
While a stompie will not ignite fuel, are you so sure that it will not ignite fuel vapours?

And of course all fuel caps are air tight..... Nooit.

Agreed, but here's an interesting link on Mythbusters Results (Spoiler alert):

Is it possible to ignite a pool of gasoline using only a cigarette?

-PARTLY PLAUSIBLE
A cigarette has the potential to light a pool of gasoline but just doesn’t have enough sustained heat. Gas ignites between 500 °F and 540 °F, the cigarette at its hottest was between 450 °F and 500 °F but only when it was actually being smoked. An ignition is very improbable.

So yeah, probably will never happen. Although this is a "pool" on gasoline, and not just the vapor. lol.

Excuse the derailment; I'm a 'first click' guy too.

The auto-stop is a safety feature... but not for what is posted above

Yup. It stops an unattended nozzle pouring petrol all over the floor when your tank is full. It has absolutely ZERO to do with the capacity of the tank.

In fact, if you look at a picture of my car's fuel tank, you'll see that the designers, being competent, have actually made it unpossible to overfill

So you can't overfill?

Like some vehicles that don't have that design feature.
 
Not quite the same.
But I opened a LPG blowtroch and held a cigarette stompie there and it did not ignite.
I flicked the stompie and there was....................flame.

SPARK does it.

lol
flicking a stompie doesn't make a spark.
Your motion of the stompie, though, increased the temperature due to increased airflow.
LPG minimum ignition temperature is 410 degrees C
Petrol minimum ignition temperature is 500 degrees C
Cigarettes burn at below 400 degrees, unless you're drawing them in which case they go up to about 450 degrees or so.

Hence the LPG igniting. Petrol won't.
