I sold my Z4M which has the S54 engine, so I have spare engine oil and filters for sale.
3 OEM filters (11 42 7 833 769) $10/each
17 qts of OEM Castrol TWS 10W-60 oil. $10/each
The pour date on the bottle is Dec 2012, but never opened, so I believe it's still good as far as shelf life goes.
I can ship the filters (with shipping fee), but won't ship the oil.
