here are my reviews for some engine oil I have tried:

Eneos FS 5w40: overall it is better than shell and petronas~ engine feels lighter when accelerate but top speed took longer time
LM MOS2 SS 10w40: better than Eneos in terms of acceleration and engine is quieter too, value for money
Motul Turbolight 10w40: a bit heavy when accelerating from stand still, but it gets better at higher RPM, can reach 180km/j quicker than LM but pricey

so, I'm reverting to LM after this, will be buying few bottles for stock~
