Hi; I recently purchased a 31000 Mike divvy 900. Have changed the oil to 10-40 shell advanced synthetic based and fitted a genuine filter. Somehow she seems noisier Am hoping someone could advise me if the oil I have used is suitable or not. The oil issue seems to be a minefield. Some are saying it should be SE oil due to age etc. Wondering if I need to drain and start again. Many thanks for your help in advance.
