agree. will go for fully since fully syn not too pricy compared to semi also

tenkiu for ur inputs. appreciate it =)

no experience with mineral. I'm using fully

when servicing your bike, try peep the colour of oil

initially I tried change at 3k. but the colour I noticed quite dark

and now my usual interval is 2.5k and change oil filter every 2 times oil change

fully. kapcai

3 years ady time flies

i just stick with yamaha fully black 10W-40 (the one on post#1)

brands aside, i think changing periodically is more important

best is to follow the manual, also depends on your riding style

perhaps you can try changing to fully and see if there is any difference in daily ride

if not much difference then probably can switch back to mineral?

but if really sayang engine pakai fully lor
