Any good 5w-20 or 5w-30 with a MC filter is what I would recommend. Our 2001 Taurus with the Vulcan motor was happy with QSGB and a MC filter right up to 180,000 miles when the TC went out. If you prefer synthetic blend QS Defy would be a solid choice.
The 3.0 Vulcan in my 2007 Taurus seems happy with Smitty's Super S (either 5w-20 or 5w-30) and a MC filter every 5,000 miles.
I get the Smitty's at Menards on sale for $8 per 5 qt jug. I get MC filters from AAP using an online discount code. Makes for an inexpensive oil change.
