what type (example 10w50) is best to use on a 350i engine ,I am about to change to new oil,just be sure the engine is well maintained, read a few threads that the engine could be turning hot in traffic so ticker oil is an option?
filled it up today and took it for a short drive,oil-pressure was better with the new 20w50 oil, perhaps the previous oil was no good or the new one is much better!
