The dealer was supposed to give me an oil change with BMW Synthetic Oil, but I am not sure if they did. I asked, and they said that they did, but when looking at the oil on the dipstick it looks really dark, as compared to my other BMW that has Mobil 1 in it right now. I would think Mobil 1 and BMW Synthetic would have a similar color. Does the darker color represent mineral oil in the car? The car only has 3000 miles on it, and this was its first oil change. Did the dealer give me non synthetic oil? Please let me know if you have any opinions.
