Can any one verify the above......
So any synthetic oil which is 0-40w,5-40w, 5-30w should be good.......
Am i right guys......
I have a E87, 118i (2005) ......

No! Not only those oil weights... but the oil
ALSO must meet BMW specs:
Long Life 1 or
Long Life 4 rated, PLUS it also must be of least
API SM/CF, ACEA C2, C3. LL-4 can be used where LL-1 is spec'd for. But LL-1 can not be used for LL-4 areas.
LL-1 = high sulfur fuel (USA/Canada/Mex/Austrailia/ect...)
LL-4 = low sulfur fuel (Germany/ECE)
BMW says to use an oil that meets the above oil specs (
API SM/CF, ACEA C2, C3; LL-1 or LL-4) and that comes in a
5w30,
0w30, or
0w40 weight.
