brand: Petronas Mach5
model: 20W-50

feedback: so-so. not so good, not so bad... better than Mach5.

brand: Petronas Syntium 800
model: 10W-30
price: ~RM110 (forgot exact price)
feedback: i think this is one of the best oil grade to be used in CPS engine. however, being Petronas I dont think it will last longer than 5k. only used once, cannot elaborate much. and expensive compare to other brand too since it's in 3L and 1L package...

brand: Shell Helix HX7
model: 10W-40
price: RM99
feedback: I think one of the best oil for CPS engine though Proton recommends 10W-30... still, i wouldn't recommend for usage exceeding 5k... might be usable, but not recommended...
