What is your experience with audi 2.5 TDI (103kW) engine oil capacity?

The manual says:

-5.5 liters (without oil filter)
-6.0 liters (including oil filter)

I have done it 6 times with my 1996. engine, since I bought it a few yrs
ago, and it always swallows almost 7.0 liters incl. oil filter (I always
change the filter). Did it yesterday, and can't live with the mistery
anymore :-)

THNX very much.
