e 46 engine knock (after oil change to non-synthetic oil) -attached video as well
I change my regular bmw oil to 10w 30 shell non- synthetic oil from bjs and 1 week later my engine makes that noise as you can see in the video. I am concern about this, could you please tell me if you experience something like this. Could this be due to oil change? or is it vanos?
ITS 2001 325i with 184k,
always used bmw fluid until last week
