the moment you start the engine, it is already "breaking in", only it is very very slow. Normally, breaking in has two different approach, one is soft and another is hard. Soft break in involves driving slowly (usually for the first 1,000km) at speed not exceeding 110-120kmh. Hard break in is the complete opposite of soft break in, usually stretches the car to its upmost limit for hardcore drivers. Both has its pros and cons.

However, both types of break in shares a same basic rule: Do not let the engine to stay on a specific rpm for too long. This is especially important for those taking their new car for a leisurely drive/outstation trip. It is important to vary the engine rpm throughout the entire journey.

How to break in? Just drive. To go below (soft break in) or beyond (hard break in) 120kph, that's your choice.

simple word..'Lenjan' your engine to the max..

break in to keep our engine at the best performance, overlasting..and the engine very smooth to accelerate our desired speed..
give u example:
1. a new 100cc cub chai = once get the car, no break in, just drive like others cub... one day the rider ask why his cub only can go max 110kmh?

2. a new 100cc cub chai, same model with no.1 = 1st 1000km he control the speed below 80kmh..after 1st service, he do proper break in, and he realized that his engine very smooth and easy to get 135kmh even a standard 100cc cubchai...

for a car, by break in the engine, we allow and give A STEP TO STEP EXPERIENCE to the piston and engine to achieve maximum speed.. i dont say go for maximum 200kmh.. if got chance to get 160kmh for few minutes ok already..then slowly reduce the speed constantly...

maybe..one day someone claim he got maximum 240kmh with standard preve..  and when we ask them, they will said they do proper break in when their engine still virgin.. 

p/s : i can give u 18SX example for better understanding, but im respect silent reader here, maybe women,girl, is reading and learning how to be Turbowoman..ohhhh..hoho

so no solution ?

"the moment you start the engine, it is already "breaking in""

from the very first day you got your car.

If you do it after 1000km, you probably wont be getting the full benefits of doing hard break in from the beginning.

its up to personal preference. I dont like engine lembik, therefore I am a hard believer of hard break in.

then, original Lancer vs Inspira standard incident at LPT story on previous month give the answer... when the Inspira later say bye bye to Lancer..

maybe Lancer soft brake in then Inspira already poison by Proton do hard break in... then we see who beat who..

p/s: Fast & Furious mode, but seatbelt still must use one..

Yes,this is what a man who's well-versed with engine oi would say!Thx bro!
Damn, its Inspila yo..At least not Persona Test Drive...
Hahaha..Just kiding kiapreve
I literally ROFL at this statement..
Wahlauweii...Not u too saying my name twice..

Wow.. So far u're te 2nd person I saw that FC.Nice bro!

So nice    you inspira wor...
I got Persona Test drive car only last time when mine car stayed at MD Service Centre for 4 days 3 nights.

Hope, they can fixed all of your major problems. 

Later, this thread will become a test drive car story...all posting their test drive car instead of preve.

Hi there, I have a few question here.

1) there are some rattling sound on the driver door panel. Are they able to solve it?-i think so
2) GPS on preve cfe. Any updates? I can't enter coordinate. And there's a lot of road which are unavailable.-see the latest firmware at the 1st page,most probably not yet
3) the double din touch screen Memang cannot play DVD?-cannot
4) boot lid self open. DIY or send it to proton.send sc,known issue
5) fan doesn't ON even at 1/2 temperature unless AC ON-this 1 i dunno
6) noisy radio. Other media ok.what do u mean noisey radio?poor reception?
7) over cranking sometimes during start up.send to sc,most probably owv problem
8) blinking LCD display. Any fixing???-somepne suggested not to set the brightness to auto,just set to night or day manually

Sorry for all the question above. But can anyone enlighten me????

Thanks and appreciated.

Just gv my white tiger a bath...a lot of small small brown spot cannot be removed...

c pillar they add wat silicon at wat place o? cos i am kinda annoyed by the wind noise edi, gonna fucuk them gao gao if they cannot fix it. Cos the dealer boss even ask my dad for breakfast and give us 2 Isuzu jackets to say sorry, cos the dealer boss is proton and isuzu showroom together one.

Guys.. Any regrets buying preve? My colleagued wanted to place booking, but looking at this topic looks like so many problems laa
