ED35 took half a litre when 4000 miles old...only 3k after it's checkup service. I imagine it'll need some more again before the next service! As they bed in over their first 10k they tend to get better and seal more effectively.
With regards to coolant, I've found on the plant we used to operate that coolant levels tend to find their own level, and this can sometimes be right on the low level mark, but isn't a problem. If it continues to drop it's worth investigating
