I am trying with Royal Purple 5W-30. Later might change to 5W-20 and see how different it feels. (lower is always better). I chose this brand because it is pretty cheap compare to others, and I like the oil colour (Purple colour one, hehehe).arechin said:according to u..
wat kind of engine oil u used now?
n how was it?
Usually more expensive full synthetic oil has better protection because they got external molecules which make more oil molecule to stick to ur metal and not easily slipped back into the oil tank if we never ride bike for quite some time. Of course, there are external substances which ensure the oil don't contaminate so quickly at high temperature, so tat we can use the oil for higher mileage.
I heard from frens that Mobil1 and Castrol are good. Motul and Redline are top class in car racing world. Maybe I'll give a try to other brands if I found Royal Purple isn't good. Well, my fren from oil engineering told me it's not good to mix various brands because the external substances are different and not good for engine, so I try not to switch brand unless it gives me bad performance
