A few days ago I bought a 94 Ford F-150 pickup with a 5.8 litre(351 cubic in.) engine. I noticed the oil looked black and needed a change. Living over 100 miles from an Advance Auto Parts or Wal-Mart, I went to my local friendly Ford dealer to purchase a couple of Motorcraft fl-820s oil filters. Their price was $7.75 each not including tax. If Wal-Mart can sell them for $2.77 each and still make a profit I figure Ford must have atleast a 200% markup. If they have that kind of markup on something as common and competitive as an oil filter, What kind of profit do they make on parts that can only be purchased through Ford? Does anyone have any idea or any inside information? I realise this is not exactly an oil related question, but after thinking about it I couldn't help but ask. TIA for any replies.
