Would love to run Mobil 1 0w40 but it's not the recommended viscosity and would be a waste at 5k oci during warranty.
I thought the 2011 F-150 spec's 5W-20 oil and your 1998 originally spec'd 5w30 but could use 5W-20 also. The Kendall 5W-20 should run just fine in your subzero temps. Even the 5w30 should be ok. Kendall is made by Conoco Phillips, as is the recommended Motorcraft oil, they are similar. I use Motorcraft 5W-20 in my 2002 F-150, which sits outside 24/7 and it strarts just fine in below 0 temps when using a quality oil filter with a good ADBV material and construction.

The ecoboost 3.5L requires 5w30 for the turbos. Which is why I'm leaning torwards justing using a Full Synthetic 5w30 instead of a blend.
I dont live in Ames anymore, moved to Boone. Used to sell Fords last year in Ankeny and sold several Fords with Ecoboost motors. The difference in the Ecoboost in the Taurus and Flex at the time we were told was that the turbo was not oil cooled, so you do not have to worry about coking up a turbocharger. Id run Quaker State Ultimate Durability. Its fairly inexpensive and passes the old GM "vette" spec so its a decent oil to use for anything that makes some good power. If you are looking for cheaper Kendall, then the place for it is Theisens. It runs about 3.30 a quart.
Thanks for the info, was that at Dewey? I thought i read somewhere that part of the turbo is lubed by oil and it is watercooled. I have some Quaker State Ultimate Durability not sure how comfortable i am running it in the ecoboost even tho it is HT-06 rated. Id feel more comfortable with a top tier synthetic.
