Black Oil Advice needed

Zedster
in BMW X3 Series Forum

Featured Replies

I am looking to buy a B47 engine. I have found a X3 with 72k on clock with very good BMW service history according to the in car service record. It has 10 stamps roughly one a year. 

Generally the car appears mechanically sound. But when I check the oil it is jet black, like nothing I have ever seen before. No translucency  at all. According to the service record BMW changed the oil 7 months ago at 68k. Is it normal for the oil to be this black after only 4k miles?

    Welcome to the Forum

    Makes you wonder about the service book is it really for the same car? Then again with extended service periods the oil will get very black and thick.

    If the engine is running well first job would be drain some oil then add an engine flushing agent run the engine to clean as much crud as possible then drain and new filter, add cheap oil and more flushing agent and repeat after a couple of flushes it should be much cleaner inside then Filter and a Good Oil
