i use motorex 15/50 semi syn in mine.. seems to do well.. at 12 months and 4000km my oil does not even look dirty and still looks new.. so i wonder if i should bother to change it... baghira manuals sez every 4000km, yamaha manual for the same engine/filter size and oil capacity sez every 6000km... and that assumes using regular car oils... i never pay attention to the every 6 months thing.. good moto oil does not go bad that quick.
