10 quarts of oil is usually fine, no?
If I let mine drain for a full 30 mins, it'll take 9.5+ quarts and still read half on the oil gauge.
What oil was used and what was the spark plug interval? 37.5k per BMWs rec? This kinda case supports the hypothesis that main bearings might be behind this. Nik Saran might be right about plug interval factoring into this.
Sorry for your loss & wallet.
