This is one you'll hear a lot of conflicting stories from "ALWAYS use the same brand and weight motor oil at each oil change and top off with the SAME brand and weight" to "if the API rating is the same mix 'em to your heart's content". I'm in the middle for my pick-up, it gets an oil change every 5,000 miles most of the time I use Castrol, Motorcraft or Valvoline and since I'm not as stubborn as I used to be I use the recommended 5W-20, not the 10W-40 I used to like.
