one never really remembers the capacity of their car in the tank and its all guess work as you don't get a reading just a estimate so.... does the pump auto stop or is it manual

The pump has a sensor when the tank has reached its capacity, you'll feel a click in the finger trigger. You can safely fill up to about 3 clicks over just to cram as much in as poss for a long journey.

I agree with Peter G. The pump should detect the back pressure at the nozzle as the tank reaches capacity and trip off; you can squeeze a little more in by squeezing the trigger again, but not beyond the second time it trips.
The Law of Sod dictates that one day the pump won't stop when you're in your best gear and shoes!

The Pump should switch off when the tank is full.
The nozzle of the pump senses the air back pressure coming out the tank as it fills up and switches off automatically so you don't have to worry about over filling your tank.

In UK petrol stations the pump stops feeding the fuel into your car when your tank is full and the fuel reaches the end of the nozzle.
In our council yard the diesel just keeps on going until it spills out all over your boots.
So it depends where you fuel up really.

Providing the plastic seal at the nozzle is in working order, a pressure switch in the pump will shut off the pump motor when a set pressure is reached,, say when the the tank is full and pressure rises.
The pumps are serviced regularly to maintain safety.

A properly operating nozzle will cut off when the tank is full. Occasionally, they malfunction, and you will have gas shooting out of the tank, but I have only seen this happen a couple times in the last 30 years or so.

pumps have a sensor that shuts the pump off when it senses fuel at the end of the nozzle. as far as i know all gas pumps have this as it is required as a safety feature by law here in the US. don't know about other countries. all else fails ask an attendant or other person who looks like they might know at the station.
God Bless

It will stop automatically when petrol starts going back up the nozzle and trips a sensor when the tank is full.

It "should" stop as soon as the end of the nozzle gets under the surface. Also it should prevent the nozzle working unless it is pointed below horizontal. I think this is legislative requirement for self service, as is removal of lock button. However if you rely on this you will get a wet foot sooner or later

We have regulators on ours (in the state of Missouri, in the USA) that shuts off but you can over-ride them simply by depressing the "trigger" as many times as you wish. It's not considered "good" to "top off the tank" but many do. Personally, I like to round off to a 0 or 5. It's almost a superstition; I should stop since it's meaningless.
