Which engine oil suits the BMW E90?
The oil must meet BMW's Longlife specification LL-01 or LL-04, and the viscosity must be between 0W-30 and 5W-40. The brand does not matter as long as the specification and viscosity match.
Which oil suits the N54 petrol engine (335i)?
A 0W-30 or 5W-30 that meets the specifications is suitable. Oils intended for racing cars are not recommended, because the engine's oil circulation may not cope with such a thick oil.
Which oil for a diesel with a particulate filter?
In a diesel with a particulate filter (e.g. 330d) the oil must be BMW LL-04 approved. The requirement concerns protecting the filter. With an oil of another class the change interval may be shorter, so check the approval on the container.
