if it calls for 5-20 your alright, ford motors do like ford oil thats for sure, another good one i have found for the 4.6 is castrol syntec, been having good luck with ours

Stick w/ motorcraft oil & filters.

I have the same car. I've tried both Motorcraft 5W-20 and PP 5W-20. Both work very well. Right now I'm using the PP! I always use the Motorcraft filter.
I make three or four 800 mile round trips a year (San Diego to Phoenix) and both oils work fine - even in the middle of summer in Ca. and Arizona deserts!

The PP with the 15.00 rebate from Wallymart is hard to beat. Great oil and an excellent price!

Ford recommends 5W-20 for this car/engine/year. You could use 5w30, but in my personal opinion, I don't really see much benefit from it.

Stick with 5W20 either way.
