hope is that crank sensor lar... anyone here encounter this kind of syntom? battery ok but cannot start the car?

Have you ever upgraded your ECU's firmware? Because mine is May 2010 and one day I couldn't start my engine. It cranked...but died off after that. I had to fully press the throttle, let off and crank. It could start after I tried a few times...and I drove to SC straightaway. They said I need to upgrade the firmware because early batch has this problem. I'm not sure how true is that, but I had since upgraded and never had the problem anymore (had been a month). I had this problem three times already before upgrading.

For me is hard to start the car during hot day..
They replaced crank sensor for me already..
Until now it happen only once after replacing the crank sensor..
Yup. Crank sensor is common problem to persona.. 

My persona also the old one..
Today officially 2years old and no more proton warranty 
Please beware that crank sensor.. It will cost you RM 360 to replace it 

Are you sure 3years?
I thought persona come with 2years warranty plus extended warranty another 3years?

You better double confirm..
When you bought your persona? mine is august 2009

Hahaha nice one 
How old are you wor?

Haiz.. why mine only 2years.. 

Oh ok. DIN45R is stock size right?
I get extended warranty.. It cover only engine and gearbox.. Mostly there only 

Step harder on the accelerator pedal

depend normally ur car carry how many passengers geh...
for my previous car, saga 6years suspension still good...
but persona dunno y, now 4 suspension also have guak guak sound whenever got passenger go in/out.

dun wan change car to proton ady lo next target car will be MPV lo..as family car lo

To clarify, when I say engine oil black, it is not really black. More like light or dark brown BUT still transparent. That is normal.

If it is really a non translucent black.....its time to change oil. Usually the non transparent black also comes with a bit of honeylike feel already and contaminant is over the oil suspension limit. If only 3K mileage, maybe its a low quality lube or a fake.

If used lube at 8K mileage only a bit brownish....I not sure if its detergent function or contaminant suspension is working very well. So still have doubt but maybe magnatec has a different tech for that.

Btw...I mention a few times liao. Magnatec in Malaysia is a semi. Should use up to 5K only. If FS, still debatable..

Autofoam add quite a lot of weight to the car....if our low end torque already underpower liao...don't know how it will turns out for your FC and pulling power after that. Gain silent, loss acceleration power?

waja cps sound insulation better than PE?is it serious?i feel my PE h line can compare wit my fren waja cps lo..hehe

v can view the foam 1st at his shop..then juz decide..according the comment from the user,it is good and the product similiar wit autofoam or profoam..dun wori..i will ask his sunday got open or not..if open,then u can join us..

bulk order for EA form:

my tyre is 17inch,potenze RE001..my tyre oso very noisy lo..still got 70% thread

5k KMs lo. 5k-7k KMs lah.
Can. Remove the whole plastic scope, fit sponge at the joints before refitting the plastic scope again.
Potenza very quiet when new. But u must also take into account that he's using 215/45/17, which is actually quite thin compared to stock tyres. The thinner the tyres are, they're bound to be noisier.
Economy not good lah.. Backside also he sell..

SIEN AH!!!

Tie rod problem? U verified this at SC or what? But ur car still considered quite new rite?

Yes.

If it is still very dark brown (almost black) BUT still transparent looking, still ok but if its black and practically non transparent, its best to start planning for oil change. If waited too long, it might start to become honeylike..

Normally if change at 5K, it will rarely hit this level unless its an old engine with lots of deposits inside. However if exceed 5K, better check constantly. Note that this relates to contaminant suspension that can form sludge. Addictives will still start to wear out after 5K in general.

Only exception should be true FS or those extended mileage FS (specifically designed for extra mileage, more longer lasting addictives).

Ultimate damage to ur engine = always high rev F&F + never service car. Ur engine will become like lorry engine in no time

If u wan comfort, then stock tyre thickness is good lah. It comes down to the tyre thread as well.

Change around 8k = void warranty. If u dun mind then go ahead lah. To be safe, dun drag ur engine oil more than 7k KMs lah.

Which rubber become sticky? Rubber sticky = it's starting to melt. And rear view mirror loose? our rear view mirror is clip-on type. Maybe it's not secured to it's latch properly.

I dun care man.. I shall burn petrol till the very last drop there is on earth..

On leave today, spend whole day out till now.

Weight 30 on borderline maybe ok, maybe not, can always try then see 1 or 2 years later engine need to change or not. I also don't know, so why risk it to save some FC. Not worth the price of engine. Last time i say if use weight 20, SURE 1 year later need to upgrade engine to CPS version. As Zen mentioned a few times, our engines are long stroke engine (whatever that means), high rev, higher heat generation requires at least weight 40 to be safe.

CPS uses weight 30, but its designed might have lower the heat generated by engine, so not as hot as original non CPS version.

As for recommended engine oil.....really no recommended wan, I do know even if 2 PE using same lube, they might produce slightly different result. Most swear by semi syn Castrol Magnatec. Shell they say get black fast no good (thats misconception, get black fast might also mean lube doing of of its function to clean engine and suspend contaminants). Unless car lose power before 5K change, I would say lube still working very well....as long as its still dark brown and transparent, not superblack.

Personally, I think most branded lube also ok, just don't use China-branded wan unless you're very sure of its quality and qc. Avoid buying branded popular lube in any spare part shops unless you're VERY familiar of the shops trustworthiness...coz the most damage any brand of lube can do is FAKE brand.
