Re: Top up engine oil
Since yours is 4 pot, what was said might not be applicable.
By the way, for N52, it should be 5-30 with HTHS > 3.5.

No choice go to JB "M-One"
They advise that for 5 series Black engine cover use 5W40, Silver engine cover use 0W40
Will try next servicing change to 5W40 original BMW engine oil at "M-One"
If top up is required around 8k km (after last oil change), it is normal. There is no diff btw 0w-40 or 5w-40.C3P0;1010215 said:PML everything also say normal. But luckily they didn't do anything for you also, otherwise sure get tok. You can go to any outside workshop and try to troubleshoot the problem, cheaper also....
