Im not sure if i posted this thread at the correct place and no entry was found regarding this matter (maybe i overlook). I own an e60 523I, I am wondering anyone of you who owns this particular model have the same problem with me. The engine oil level will be low after a few months of driving and owes need to add in new engine oil. Is this normal or maybe leaking? And also, can the microfilter be changed by DIY? Cauz Im lazy to make appointment with auto bavaria to send it in for microfilter replacement only. Thanks ppl for your input! Cheers!</p></blockquote><p></p>
