My 8.1 does use about 1/2 quart between 4000 miles changes..
ya its about a quart every 5,000 miles so far.
about a quart every 2k-2.5k for mine. 2001 6.0l with 150k.
I aquired some synthetic oil at work and will see if it uses less but I doubt it.
A good synthetic should aid in slowing down oil consumption.
I switched over to a 10w-30 valvoline synthetic and a can of BG MOA yesterday with the oil change. We will see if that slows it down using a little thicker oil.
