So meaning the petronas fully syn oil is the culprit here? nazakia csl using petronas syntium 3000 5w-30.

herm, if go back there what they normally do or is there possibility due to the car hardly use, just short route everyday causing the engine part cannot bond with the premium oil

Water refill for wiper is the blue cap.. This is beside the radiator.. Not sure is it a coolant fluid for the radiator.. Anyone can clarify this? 

Ohhh.. My mileage now is 900km.. I heard add tap water not good for long run as it will spoilt the radiator.. But is this what usually people do?

How do we drain out everything? Used it till empty?

Shop dont sell ready made coolant where can just pour in? Need dilute wit boiled water mixed and pour inside? 

Don't be naive ler    ANY water will DO. Even you put distil water eventually the rust inside your engine block will TURN it back to rusty water. What you need is ENSURE its not dry (if its reducing tremendously mean something wrong with engine)

just got my 2013's 1.6SX Titanium Silver on 12012013 from 070. already clocked around 465km so far. always maintaining < 3000rpm. currently got 7.7l/100km. the fastest speed i have drove only 125km/h at Lebuhraya Pantai Timur. very stable on highway. very confident in cornering at Karak Highway. really can feel the stock tyres 'menggigit jalan' the only draw back is the sound from stock tyres.

NO rattling dashboard sound. NO sound from either front doors. NO pulling left or right. so far so good

1. looks like i have to wait for this coming weekend only to found out the answer... or is there any other way to check that we have 6 not 4 speeds?  
2. ok 5 years from KIA (engine, transmission and drive trains)
3. huhu OK

in that 20km have you ever 'dive' into poholes/ bumps etc?

i have tried google but can't find the details old vs new HU like other than improved CPU etc
