I use Mobil One extended performance, $27 for 5 qt container (Mobil One synthetic $25 5 qt container)at Walley Mart, 1998,Taurus has 205150 miles, I drive car for work, changing oil every 3000 miles became a pain in the a**, once a month. I do change the filter after 6K, change oil at 12k, oil is advertised to last 15k.
