City drive 70percent. Mostly 60kmh to 90kmh
When I got the car new, the FC is far better than this.

I see. Any 3rd party proton service centre that can recommend? Will this give proton excuse to void our warranty if service there?

Better get them to check on this...
Oh.. and for the engine lube, I heard if at proton authorized service centre they won't allow this... meanwhile those 3rd pt proton service may accept it.

Can't comment on this... never been to any 3rd pt b4...
Bringing own lube is always not recommended by Proton, only at 3rd pt they may let you do this... Your warranty less likely getting void if 3rd party agree to use lube u brought your own... but still its better to double check with them first before deciding... you can find their outlet phone number in proton site and give them a call.

So far those installed this didn't complain anymore... but if the rattling is not caused by the dashboard like wires... then it cannot solve

Regarding your rattling dashboard, is it the same noise as previously before sending to SC? because such a coincidence mine also sent to SC fix, previous sound at passenger side is no more, but new sound appear... sounds like something inside the dashboard is knocking the plastic or what which no longer at passenger side like I previously had, its more on driver side or behind HU

Correct. I'm facing similar issue where the sound comes from the driver side (around steering and speedometer area) and somewhere around HU as well. Can this be fix, though if I'm sending my car to SC by tomorrow?

Wow. That's really bad.
I guess the sound is because u carry the key down and close the door?

300 to 320 full tank is in what kind of driving condition?  if assuming u used RM80 of ron95 to travel only 320km, that convert to a 9.2km/l... that's pretty bad unless you're on 100% city drive with speed not more than 50km/h and lots of jam...

Eh... I am no boss.. but I do agree with the meet up 
I duno how to friendly honk... today just saw one Premium beside me at Bukit Puchong bridge and suddenly think of this
but mana tau when cornering it came makan my lane... luckily I had an eye on it 
The rattling noise at passenger side from before has completely vanished.

But...

New rattling noise like somewhere in the stering or cluster meter appear pula 

But very rare occasion only... like today never encounter any noise

Correct. I'm facing similar issue where the sound comes from the driver side (around steering and speedometer area) and somewhere around HU as well. Can this be fix, though if I'm sending my car to SC by tomorrow?

If i forget to lock my car after i leave ,  will iybe locked automatically?
