I use Motul 5100 10w-40 runs decent, change every 3000km, i have reached 20,000km for a while... you need to change the factory oil quick, 1st change like 500km, it's crap they put it in.

but be really careful when replace the oil filter, contra to common sense, the hole must facing out... if you mix up oil flow direction, the result could be blown oil filter cap and possible more damage. so a pre warnning

I bough a few spare factory oil filter, both front and rear have rubber seal attached to.
