We just received the first report for my brother's new 335D, I am happy it looks very good for an engine still breaking in. We plan on doing 7,500 mile changes between the dealer scheduled 15,000 miles. With a TBN of 3 after just 5,000 miles this looks like a nice interval. Filter was OEM Mann. Oil was M1 ESP, not the EP formula as Blackstone wrote down.
