Motorcraft also has a Full Synthetic. Maybe not carried at Wal*Mart, but is found at Ford Lincoln Mercury dealerships. I've always thought that if you can afford a new car, then put good oil in it. Value comes to mind also. It's a lot cheaper to use a decent Full Synthetic like Lucas, Red Line, Mobil 1, Royal Purple, Amsoil, blah, blah, blah.....and go with the extended oil change intervals. At $4 a quart for over the counter conventional, in 1 year, you go through 5 times as much oil changing it every 3,000 miles. So figure that at $20 per quart for however many quarts your car needs. As opposed to $8 per quart for brand name Full Synthetic. The same rough formula applies to the filters you use. Extended oil change interval with a K&N or Mobil filter, $12 - 5 discount $4 filters, $20.
