E46 what engine oil should I use?
Any oil that meets the carmaker's requirement will do. The most common choice for M54 engines is 5W-40, which must meet the BMW Longlife grade (LL-98). LL-01 is also fine, and LL-04 works if you cannot find LL-01.
E46 330i requires LL-04 oil, what fits?
A 5W-40 oil that meets the BMW LL-04 requirement fits the 330i. Check the requirement on the side of the oil bottle, not just the viscosity.
What oil does the E46 M3 need in winter?
The official oil for the M3's S54 engine is 10W-60. According to the owner's manual, 5W-50 or 10W-40 oil can also be used in temperatures below -20 degrees. In southern Finland's frosts 10W-60 works, but in Lapland it is not necessarily the best choice for cold starts.
