High oil level

High oil level
I got my oil changed about 1800 miles ago but today it gave an alert that the oil level is too high for the first time...anyone seen this happen before?
Temps have been consistent 30-50deg the last couple months..

For peace of mind suggest you drive the car for 20 minutes at highway speeds and then check the oil level. This will cause water and other high boiling liquids that accumulate to evaporate and and provide a true read. Had this same issue with a brand new Mercedes after driving short distances.

Yea this happened to me about 2-3 days after I bought my first 992 (2021 C2). Brought it back to the dealer just in case and they said no issue, but I made them change out oil just in case to reset the level and the issue did resolve itself. It never came back on again.

A good way to ensure that any moisture has been removed from the oil is to drive the car until the oil temperature is greater than the boiling point of water at your altitude. (213*F+ @ Sea Level)
Unless/until all of the moisture has departed from the oil, the temperature of the oil, along with any moisture that is present in the oil, will not exceed the boiling point of the water.
Just to be really, really sure, an oil temperature 10*F above the boiling point of water makes for a nice Insurance policy. FWIW, This increase above the boiling point is called Superheat.

Who did the oil service?
992’s are finicky on oil capacity. If you had someone who just read the oil spec capacity and dumped it all in, then you probably have too much oil in the car. The right way to do it is add incrementally, start with about 7 quarts. Run the engine to temp, turn off and measure. Then add. Repeat the above, never adding more than a quart at a time. Takes a while, I usually do thee cycles before getting it right on the upper mark.
the sump is huge on a 911, it doesn’t all drain out. Sometimes you get an 8 quart drain, other times 9, or maybe 10. Depends on how lever the car is, how hot the oil, and how long left to drain.

That's seems tedious and time consuming... no shop or dealer would ever do it this way due to the expense.
Just get the oil warmed, open the drain plug (use caution), level the car until the oil is fully drained, replace the filter, and add the 8.3 liters (8.77qts) of oil as specified in the factory procedure. One and done every time - no need to 'over engineer' such a basic procedure.
From the 992 factory service procedure:

I have done seven oil changes on 991,s and 992’s, the dump and go method you suggest doesn’t work well, and usually results in an overfill dash message.

Two changes on my 992, and changed oil on a zillion cars for 40+ years. Ppl can make their own choices, but I personally don't have time for superstition.
I submit three points for review:
1) 992 oil change at what appears to be a foreign dealer. At 3:13 the tech ads a pre measured quantity of oil. One and done.
.
2) Silliest oil change ever. Painters tape all over the spoiler? Ridiculous funnel? Why would anybody knowingly underfill the car with 7 qts to start? 'Critical oil 'level'? no thanks. The internet at its very worst.:
.
3) A review of the factory procedure merely states 'Slowly pour in new engine oil using a clean container or filler nozzle'. My strong suspicion is that most ppl don't actually know the 'official' capacity (8.3l) since it's not published in the owners manual, which leads to the 'incremental approach'. In this case the data will set you free.
>>I have done seven oil changes on 991,s and 992’s, the dump and go method you suggest doesn’t work well, and usually results in an overfill dash message.
I submit that if the car is leveled properly during drainage, the oil is pre-warmed, and sufficient time is allowed for all the oil to drain there's zero need do the incremental fill IMHO. Again, YMMV, but this is the procedure I've been successfully following since I had hair.
Regards.

Jlegilis is right. A lot of people purposely over complicate things just because they need to tell everyone how special and esoteric our expensive toys are.

Re: High Oil Level.
I’ve had it come on if parked on a very steep incline. e.g., if you have your 911 flat-bedded and drive it on and off of the flat-bed, it can cause the oil level sensor to read erroneously.

I kind of had the opposite problem for more than a week... the oil level displayed "oil level unknown, no measurement"; it's only been 4 months since my last oil change. I did notice it started happening when temps started getting really cold here in Dallas. But luckily today, after several days of daily driving, the display is reading the oil level properly again... coincidentally when the local temps are warming up a little lol.
