Did my '00 Sable Duratec the other day with 5 quart jug of Pennzoil 5W-30, which cost $5.94 and a Motorcraft filter FL-820S for $2.94. Total cost with tax under $10 from Wally world (Walmart). I know it takes 5 1/2 quarts but I had a extra quart or 2 of Pennzoil around here.
And BTW, the guys at Bobistheoilguy.com reccomended that oil and filter for this car. If, you're not aware, go there. They know more about oil and filters than anyone as they test their used oil and cut open there used filters for testing.
Also, if you're inclined to go high end , synthtic oil, Mobil 1 was at Wally's for under $20 for the 5 quart jug.
