Roger, READ YOUR MANUAL.
Duratec and SVT Duratec both use 5.8 quarts with a filter change.
Rousch racing ran a test on our Duratecs.
At 5000 rpm there is less than 1/2 quart of oil left in the oil pan.
There should be at least a full quart in the pan at that RPM.
That is why they suggest we run with at least 6.3 quarts, which is .5 quarts more than what Ford suggests.
Why do you think so many Duratecs are throwing rods ?
You can run with what you want, but for the extra $2.25 for .5 quart,
it is cheap insurance against having to deal with a blown engine.
I've been running 6.5 quarts for the last 20,000 miles.
MPG is the same and the engine feels stronger with the Mobil 1 than with Dyno Oil.
Now, my next Oil change will be with Mobil 1 with SuperSyn. 5.8 quarts?!?!?! My Zetec only takes 4.5

From the Owner's manual, page 292: "Engine Oil Capacity | 2.5 Liter | 5.5 quarts (5.2 liters) (with filter change)" As for the Roush test/recommendations: There has been much discussion of late as to whether the thrown rod issue is an oil starvation issue, or a harmonic damper issue. I lean toward the damper school of thought, but honestly there's no way I'm qualified to figure this out on my own. (IOW, I doubt we could have an intelligent argument on the subject, and I would be at your mercy.  )

I'm assuming that they are not. Maybe Bill or Jim could verify it for us.
