1.25 quarts in 1100 miles. This is on a new 408 engine. I have never dripped one drop so I know its not a leak. Should I assume its just blowing by the rings since my tail pipe is completely black along with bumper above the borla tips? Anything I can do to reduce the blowby if thats what it is? The last oil change was on 10W-30 and now I just went to 10W-40.

Any ideas?
