Oil level after HPDE

I have a 991.2 with roughly 20k miles. I have done a Blackstone UOA after each oil change and everything appears to be quite healthy. I just did my first HPDE. I checked the display before and after the HPDE event. I drove and pushed the engine pretty dang hard for all 4 sessions. Since mine is a 991.2, it doesn't have the 'lines' on the display but I'm estimating a loss of approximately 1/8-th from max to min. I'm guessing this is completely normal but look forward to seeing what the next Blackstone report tells me. I will probably have one more HPDE done before the next oil change.

I don't track my car and generally drive pretty conservatively. I have put 20,000 miles on it since purchase. I generally keep add oil with the level gauge drops about 1/4 quart to bring it up to the full mark. Never overfill. I generally get a little smoke on cold start up for about 30 seconds. In the first 10K mile I wound up adding a about 1 quart over the course of the mileage between oil changes. After the first oil change I noticed that the level gauge remained at the full mark for the entire next 9500 miles. The owners manual states up to 1 liter of oil every 1000 km is totally normal. I became concerned as a little burn off at start up and 9500 miles of driving later I hadn't used enough oil to affect the gauge even a small amount. Just had the second oil change at the dealer and they replaced the oil level sensor as it just seemed like a good precautionary measure as it didn't make any sense not to burn even a drop of oil in that many miles. They purposely left the oil level in the middle of the range. I drove the car for a week and then added about a third of a quart to see if the new sensor was registering the added oil, which it did. Still on full now after about 500 miles and monitoring. Either I have a car that doesn't use oil (a good thing I think) or I the oil level gauge is not very reliable. FWIW I do check the oil level regularly at start up and after running when the oil temp reaches normal I will shut off on level ground, let it sit for a couple minutes and then check. It does seem odd that Porsche claims a quart per 1000 miles is completely normal as I have never had to add that much between changes 10K miles apart.

I know this is an older post by the original/string creator but it’s NOT 1.8 quarts PER SEGMENT … it’s 1.8 quarts between minimum and maximum. The amount between each segment is about 300 milliliters, or just over 10 ounces … that’s less than a 12 ounce can of beer (remember, a quart is 32 fluid ounces … 1 quart is also 946.353 milliliters)

After an oil change my oil level will read let’s say mid bar level. And I see the reading so I think perfect and done with my oil change. Then after driving another 30 miles or so my oil level drops again a bar or two. Your experience as described sounds like this. And is normal.
I have the same thing. I would just measure it after each time out on the track and see if it's the same or dropping but I would say it's "normal"
