Question about oil level

Hello.
After changing my oil ,I noticed something weird. Sometimes in the morning, my dipstick won't have any oil on it and my car's computer will tell me it's time to add some more. Then, after starting the car once or even just turning off MAR and back to ignition, oil levels are back to MAX. The surface is flat.
The bigger worry is why sometimes my dipstick doesn't have any oil on it, usually happens after the car wasn't driven for a while? On a second startup, dipstick is back to full, of course checking properly by shutting off engine, cleaning dip stick, dipping again and seeing the results. No apparent oil leaks whatsoever.

If the dipstick is dry before startup, you need more oil.

The thing is, it happens once in 10 startups. Sometimes my computer says i have a bar shy of max, sometimes empty. I filled the car with 5W-40 ,4.4L as specified when doing an oil filter change as well.

If it's anything like the Peugeot/CitroŽn oil level sensors, it will be somewhere west of vaguely unreliable. Better off using the dipstick as a true indication.

in-car oil level readouts are not always reliable.
Go by the dipstick.
If the dipstick is dry, you need more oil. There should be no argument about that. If it is dry, how can the level be even close to correct...????

What could be causing a sometimes entirely dry dipstick and sometimes brimmed to the max? Flat surface on both tests, even same spot.

I think going by the manual,if it's filled to the correct level there should be a bar 'empty' on the computer.

If it is going all the way up to the top end of the mesh (as in the photo) then it is correctly and fully filled.

It looks like you've tipped the dipstick and the oil has run to the top showing a false reading.

I cannot understand what the issue is here, as David says, the dip stick is your control, not some unreliable electronic read-out.

Check oil when car is cold on a flat surface, or at least well after a journey to allow the oil to drain into the sump.

Dip stick out, wipe, dip, read, wipe, dip read, or if you own a 159 repeat about twenty times until you get a reading.

There is nothing else to it

Filled to the top it should show ALL bars and say "Oil Level". If it says "Maximum Oil Level" instead it means it's overfilled apparently even though you'd read that as being correctly filled to the brim in the usual English sense. Italian translation problems I suspect.

And pull and wipe several times to get a decent reading. This gets rid of the oil that lives in the dip stick tube giving a false reading as it ends up on the mesh bit when you pull the dipstick out.

You (general sense) don't need to consult a manual to interpret the oil level on a dipstick?...... surely.

I know the question was a bit dumb, but i prefer to ask before doing something bad to my car. After all, nothing is more important than oil. I checked it correctly, cleaning a couple of times and checking, always full of oil right up to the end of the mesh part. Guess I'm in the safe.

P.S. Totally unrelated, but do JTD 8V and JTD 16V have the same front left drive shaft? Looking to buy a new one and found a good for sale ,but from an 8V?

Y'know, if I were to make a list of ALL the dumb questions asked by ALL of us on this forum and listed us from top to bottom in order of "who is the biggest horses ass" (myself included) I am sure tishobg would pretty much be at the bottom of the list.

I wasn't suggesting it was a dumb question. My god we've seen our fair share of doozers on here.

I apologise if you took it that way.

As I stressed in my reply, "YOU" was meant in a general sense, not specific to the OP.

I know it sounds daft but occasionally oil does not seem to "stick" to the dipstick.

I've pulled out the dipstick and no level (or oil) appears on it. Wiped the stick, redipped and the level is then shown.

I don't know why but it does happen.

All is good , it's my first experience with cars ,which turns every single thing it makes in a question mark in my head, hence the quantity of threads I start. Thanks you all for your help, better to be safe than sorry.

My 156 TS would give a different level on the dipstick depending which way round you put it in.
If you twisted it, it was different again.

I went for the method that gave the lowest reading, which for that was hatching facing away from me and no twisting.
Fresh clean oil can be very difficult to see. So for that, carefully roll the dipstick on clean tissue/cloth to see the level while being carefull not to tip it up and have it run up the dipstick...

My 159 was an absolute PITA as I mentioned previously, the Lexus is marginally better, Mrs. V's Seat Mii is just about impossible, I need a torch to reflect off the oil and my best readers.

2008 147 1.9 JTD 16v manual on the subject of oil levels. With the dipstick showing 'full', my dash display corresponds with the LH 'normal' 4-bar image in the attached. It's completely consistent on reasonably level ground, I've checked it several times to see whether I could trust it.

I ground the hatching away on 1 side, which makes the level actually a lot easier to see.
