Hello everyone,
Looking for your opinions and insight. Recently took my 2017 Alfa Giulia 2.0 to the dealership for an oil change. The OEM filter is the Mopar 4892339AB also known as the MO-339. The dealership did not have these filters on hand when I came in (backordered with no ETA), and used a Delco PF48 filter, which cross references the Mopar 4892339AB filter.
The Giulia 2.0 does not have a physical dipstick; you check the level using the electronic display on the infotainment. You can also view the oil level using a scan tool like wiTECH but it is not ”live,” per se, and works the same way as the infotainment display reading … There are a variety of parameters for getting the oil level (both the display and ECM data) to update, but to keep it brief, the car needs to be up to temperature, on level ground, idling for several minutes, etc.
When I got into the car in the service drive, oil change completed, the oil level display showed it was at the max level. I drove across the street, stopped, and noticed it dropped one notch (there are six notches shown on the display, each notch is 250ml). Then it dropped another notch while driving (bizarre, to me), and then the following day, dropped another notch (3 notes, 750ml total). This is when I used a borescope and took a look what filter was on the car (no leaks, thankfully), and what was on the invoice … PF48.
2 days and 139 gentle miles later, I returned to the dealership. Ironically, the oil level display goes up one notch, just before I have the oil change entirely redone anyway, and gave them the correct MO-339 I sourced online. Fresh oil, new filter, done.
I monitored the car closely over those days and there were never any DTCs or warnings, etc. Car never told me that its oil level was insufficient. Oil pressure and temperature were normal, too. The car has been entirely normal and without its oil level display fluctuating once the OEM filter was on the car.
What could possibly have been going on with the Delco filter to have caused these fluctuations in the oil level reading? Speculation is welcomed. Lastly, do you think any damage has occurred during this experience? Based on my understanding, it seems quite unlikely? I have done a Blackstone analysis previously, and will do another on the next oil change.
TL;DR -- Alfa dealership installed PF48 filter instead of MO-339 (OEM). Oil level display showed slowly decreasing oil level over 2 days / 139 miles, up to 750ml based on reading. No leaks, warnings, DTCs. Oil change redone with OEM filter. Curious why this occurred, and potential for damage.

Thank you very much!
