Leading evidence: 'Use dipstick only' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check after sitting 24hrs, seems' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Suggestion
I've found that Jake's recommendation that the level should be checked after sitting 24hrs, seems to work best as a benchmark.

I always check my oil after its sat for 24 hours and on a level surface.

With my 996 Turbo I can't check the oil cold or with the engine stopped.

But when after the engine is fully up to temperature and I stop for fuel after refueling wehn I check the oil level it is up.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

You would be amazed how much oil eventually drains down in an M96. So the answer depends somewhat on how long the engine was stopped before you took readings.
The manual specifies how much oil to add. While others like to keep the oil in the middle or just below top, I've been filling mine to the top and never had any oil smoking issues (not even on the track).
It's better to add smaller amounts and re-check in the morning, when cold, on a flat surface.
I've found that Jake's recommendation that the level should be checked after sitting 24hrs, seems to work best as a benchmark. When checked after 24 hrs, mine shows about 2 bars below top, then at fuel stops shows full or one bar down. Demonstrates how much is help suspended up in the engine.
I read somewhere that from empty to full on the oil gauge it's about 1,25 liters, so whenever it reaches the bottom bar I top up with 1 liter bottle of Mobil 1 0W40...
Wouldn't it show less full if oil was suspended up in the engine versus when cold?
Oil expands when the temperature goes up (increases in volume) when hot versus when cold, but I'm not sure how much this contributes to the reading on the 996. It did have an effect on the air cooled cars due to the shape of the oil tank.
Shows how the oil level changes with the engine up to temperature.
With my Boxster after the car has sat overnight the oil level will be down a couple of bars. But when after the engine is fully up to temperature and I stop for fuel after refueling wehn I check the oil level it is up.
I tend to keep the engine level at the max line when the oil level is checked hot. This ensures the engine has a full load of oil but is not overfilled.
With my 996 Turbo I can't check the oil cold or with the engine stopped. But like with the Boxster I tend to keep the oil level up at the max line.
Interesting, my car does exactly the opposite. After parking overnight, it will show that it's full (which I can confirm via dipstick), but frequently after refueling with the engine hot, it will show it being very low on oil. I only trust the electronic gauge when the engine is stone cold.
