My 525xi is burning oil. Also the engine now makes
more noise than when I bought it, now It has 107k
miles I use 5w30 oil. Should I use a thinker oil?
How is the CCV system? Maybe you have a leak and that is why it is making noise.... http://blog.bavauto.com/5434/bmw-m54-6-cylinder-crankcase-ventilation-pcv-diy-325i-328i-330i-525i-530i/
Do not use thicker oil! The problem needs to be properly diagnosed. Take the car to a BMW specialist.
Bob is right- find out why it is burning the oil- but if you are not prepared for the expense and hassle that a worn out BMW will give you, go ahead and try the higher weight oil- but DO NOT throw any of those fancy engine additives in there-
Thank you all for the advice. I appreciate your help!
