Actually 3 oil changes over the last two weekends but the Twingo behaved itself (apart from disgracing itself with a weepy sump washer).
My point is having drained (very drained) both the Citroen HDi and the Volvo, changed oil filter cartridges, and refilled using EXACTLY the manufacturers oil capacity; both cars showed a shortfall on the Dipstick they were both reading about 80% full and always on dead-flat ground after hours of resting.
I'm not too bothered about it but it did leave me feeling like I should top them up to "full" on the dippy.
Any thoughts out there?

Max and Min on stick are just that. I always like to run mine a few mm below max.
Many many years ago I was a powerboat mechanic, and due to different angles of engine installation or operating conditions we found that in severe cases with a very full sump the crank would splash in the oil, causing foaming, lack of performance, aerated oil entering the lube system, causing all sorts of probs. Not such a problem on road cars but thing stick in your mind from years of experience

Is this the oil level capacity including the oil filter or without?
I sometimes wonder if you're on the level Mr Welton.
Seriously though, I've done many an oil change on mine - sometimes I have about half a litre left over from 5l, sometimes it swallows the lot. Only thing that makes sense is if the quantity indicated on the container varies a bit, or something.
2002 HDi 2.2 Exec Estate, (2008-12) (wonderful)
2003 HDi 2.2 6-speed Exec Estate (2012-19) (also a gem)
2009 Citroen C5 2.0 HDi VTR+ Estate (godawful heap)
2008 BMW E91 330i touring (great fun - murdered by a reversing SUV)
2007 BMW E91 325i touring (slower smoother quieter)
To be fair I'd rather keep the level just below Max because max really is max so why risk going near it.
Conversely if most folk took a car to a garage for an oil change and saw it was short of max they'd likely complain they'd been short-changed. Perhaps garages over-fill cars for this reason. Be interesting to hear what Jasper used to do.

I have a method of filling and engine with oil....
Put in 3 litres then start the engine until the oil light goes out ...wait a minute then check the level, top up in half litre stages until the level is between min and max then wait a couple of minutes before checking again.
Finally top up to the max line...unless the car is a Volvo diesel then I would leave it between min and max as there have been problems with engines running away after diesel gets in the oil and raises it to a dangerous level.
Modern cars with the 924 drain the oil change the filter prop the oil can up with the spout in the filler hole wait for the can to fully drain then cap back on and done. None if this 3.75lt or 4.25lt nonsense like the passat or other cars I've had. A 5lt jug of oil takes it right up to the fill line on the dip stick, it's the same every time.

My experience with the PSA 'DV' engines is they always seem to take exavtly 4 litres to the max line.
I get the feeling a lot of manufacturers list the maximum capacity as being somewhere in the middle of min and max, maybe to stop people getting it seriously wrong?

Just looked up the 3.0tdi, 8.2l,,, better start saving.
I'm guessing that's just so Audi can achieve 2yr/20K service interval, at the expense of engine life of course.
2 years or 20k is a crazy amount of time / distance for oil no matter how good or well developed it is. Our passat is on 10k oil changes and the 924 is changed every 6 months.
