6 litres = 6.35qts for you standard folks.

BTW - don't forget the standard SVT fill was already a higher 5.85qts (due to the oil cooler.)
Don't know the year the standard Duratecs went to that as "Standard" fill, but IIRC it was 99.
You will notice the SVT fill specs did not change accordingly...
Why is that? Why is there more SVT oil failures? When you factor in the rate per vehicles made!!!

hmm...
The 8 oz claim at 5500rpm would go right along the right hand turn failure epidemic. Even with that little oil in the pan, if in a straight line, the pickup would be getting oil...
Gives a lot of merit IMO to this for you that "doubt" it's validity...
