Quick question. I just got my car with about 9000 miles on it from a dealership. I am ready to do my first oil change. I am going with Mobil 1 5W-30 and probably 6.5 quarts. Is that ok since I am not sure what oil has been run in it before? Just want to make the switch and run that forever. Lol. Any comments would be much appreciated. Thank you.
