you can say all this till your blue in the face, BMW's specification is a quart every 750 miles is acceptable.
I would not fix a thing, and envy that you only have to add 1 quart ever 4,000 ish miles. Search me and see what my N63 eats on a regular basis.
Why not just do an even 10k change and call it good?
