[Which oil]

[Which oil]

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.
