Changed the oil and filter in Nov 2023 and after 1 month the low oil level warning came on. Took it to Subaru dealership and they changed the oil and oil plug on Dec 5, 2023. The low oil level warning came back on 2/2/2024 while driving on the highway. Checked oil and it was fine. Drove it again the next day and again on the return from a highway trip, but off the highway, the low oil light came on again. Oil level checked fine again, but decided to add a little oil to bring the level up higher but within limits. Have not driven on the highway, but the light has not come on yet driving city roads.
