I bought this bike new and after dumping the factory fill at 1000km I have used exclusively Motul 5100 10w40 and K&N oil filter
OCI were always 6000kms.Before BITOG I was changing oil filter every OCI,now I don't.
Last oil change before UOA was without touching the filter,so from the total oil capacity of 1,7 liters,about 0,3 liters of old oil were left in which had about 4500 extra km's.
The bike is used from the begining of its life for everyday short trip commuting to work and back (5km's each) and has experienced too much city driving,but also long journeys now and then.
It does not consume any oil at all,its frequently hard driven,and the gearbox shifts quite smooth pretty much at the same manner before and immediately after an oil change.
The oil shearing effect was not noticeable in any way.
In fact the engine seems to like thin oils as it revs happier when its nice and hot.Its a small displacement and low torque engine anyway so you can tell the difference in that.
