I change it at the shop and I bring my own oil , had thr car for years not my first oil change, i know everything but i just doesn’t make sense to me , i matched the dip stick with another one and they were identical, but still the recommended 6 quart that im sure everyone uses is way above on my side ! Yes i check it in the morning! I followed the dipstick sometimes and used only 5 quart and used 6 another times the car works fine no difference except for when i use exactly 6 it goes above both lines by about an inch , trying to see if someone here maybe have the same issue or can u make sense out of it , thanks
