That's some expensive oil, at least around here.

So long as the oil meets or exceeds Fords specs, I'd think you'd be ok.

As long as you meet API and SAE spec for your engine AND you change per the manual mileage intervals, your warranty will not be affected. IOW, no extended oil change intervals while under warranty. Keep receipts and a mileage log.

Good Luck,

I've used both the 5 W 20 and 0 W 20 and don't see a differance in ethier oil.
Got trucks and cars in the fleet with 200K + miles no oil related problems or warranty issues.
