Best engine oil for BMW - Castrol vs Liqui Moly vs Shell
Time for an oil change and cant decide between:
- Castrol Edge 5W-30 LL04 (BMW recommended)
- Liqui Moly Top Tec 6200 5W-30
- Shell Helix Ultra 5W-30
All meet BMW LL-04 spec. Is there actually a difference or is oil just oil? Car is F30 330i B48.
