Motor flush safe for the X?
 

The previous owner hadn't done an oil change in a while, so the oil is pretty dirty, enough to give me one yellow and one red light on the oil service indicator. I'll be changing the oil in a couple of days, and was wondering whether I ought to do a motor flush, and have the oil pan cleaned (I'd do it myself, but it's too cold to be lying on a concrete floor :P).

Are the usual motor flush products appropriate for BMWs? Total noob here. :P

I wouldn't bother with the flush, hopefully the previous owner used Synthetic oil and if so it can go a lot longer between changes than standard oil. I would just change it with synthetic and check it after a few hundred miles.

Don't bother with motor flush. Do an extra hot oil change with a new filter if you want to flush out some gunk, and the top off with a new filter and fresh synthetic and go about your normal interval in my opinion.

Generally speaking, yellow red is when the oil is supposed to be changed. I wouldn't fault the po or worry about a flush.

no no no listen to the guys,just do Castrol syntec,abd check later,be care about the cold weather,really let it warm up.

I would not be against using Liquimoly/Lubromoly motor flush or other well regarded brand name flush (i.e., not marvel's mystery oil or other nonsense -- they have their place and it isn't in our motors). BG chemicals makes good stuff too.

Change the oil at 2x the intervals indicated by the lights if you want to keep things nice and clean.
