αποτι βλεπω αυτο το λαδι που σου λενε δεν υπαρχει στις προδιαγραφες σου:

https://mymotorlist.com/engines/bmw/s50b32/

Recommended engine oil 0W-30 / 0W-40 / 5W-30 / 5W-40 / 10W-40/ 15W-40

θα πρεπει να το αναγραφει και στο μανουαλ σου.

ομως υπαρχουν κιαλλες αποψεις:

'' This engine was designed for 10W-40 and 15W-40 which are towards the higher 40 weight. In Europe, most seem to use 10W-60 when you track it because the engine is essentially the same block as S54B32 (E46 M3).

Well, you will probably have seen us on occassions recommending a 10w-60 but only in these circumstances.

1. If the car is heavily modded and heat/oil temperatures are excessive.
2. If the car is used on track and heat/oil temperatures are excessive.
3. If it's required by the handbook.''
