Possibly, probably. Fill it when the light comes on and you wont have to worry.
All this worrying about minor details. Fill it up, go somewhere, fill it up again.
If I had to worry about fuel consumption I would ride a bike.

So you don't care what brand you use?
The thread is 'running out of fuel' not economy, or have I missed something?
It does happen.

I usually use one brand and make sure I never get the level too low. Prefer to fill up earlier than later. However if needed I dont mind using another brand except Ethanol added ones. Your reply 8 refers to economy or did i miss something.
Have just done a 990km trip in the Passat and neither ran out or brought the low fuel light on.
It does happen usually by unobservant drivers who dont watch the instruments or ones run it too close to the wind.
It's not a problem if live in a large city but sometimes in the country a brand can be difficult to find in more remote areas, particularly the Vic High Country touring.

In my fuel guzzling TSI the light comes on at 1/8th of a tank. This is usually about 100km DTE after having already done 600km.
I think if I was tooling about a remote area I'd ensure that I topped up with fuel when I got to just below 1/2 (about 400km running). On AU roads, 400km is about 5 hours driving so it's probably sensible to stop & have a break.
If you owned a Holden Craptiva V6 or similar you'd have no choice but to fill up after 400km as you'd be on empty anyway. Anything above that is a bonus.
The only other suggestion I can make is fill a 20L jerrycan with fuel and see how far you can get on a tank.

That's what the OP was thinking of doing and why he asked about consequences of running a diesel empty.
Pretty close - I once put 55.5L in my 55 litre tank, filled it right to the brim tho. The car hadn't stopped yet when I filled it, so there was some more in there still. (It happened because I believed the km to empty on the dash display ... not recommended! It said 200km when I left home, 100km later it is reading 0km remaining. Should have been sceptical because the l/100km is also wildly optimistic.)
".....wildly optimistic"
I'll say.....reality strikes home as you say in the last 100km particularly in mine with a tuning box which indicates better economy at 100 than 80 and makes the maxidot figures a joke.

That's really interesting that you don't trust the MFD. Mine is within 0.1L/100km of the calculated figure.
You realise that you can tweak the L/100 average with VCDS?
