recently i heard some rattling sound as well.
then very " ganjeong", cannot find out where is the source.

then i found the rubber clip for the rearview mirror, to fit between the mirror and front windscreen.
after i clipped it on (due to first day of apply tint, the clip has to take out)
then seems like the sound is gone..

tomorrow will go for 1k service, any SC to recommend btw?

To be honest, up until now i am very skeptical towards the idea of replacing air filters and gain accelerations. Improve in a very slight margin, yes but i think the effect will be minimum and most probably negligible.

Unless we are talking about changing more than just the filters.

Theoretically speaking, you have to lose some to gain some. Basic laws of physics. If indeed there is a an increase in acceleration then there's an increase in fuel consumption. I remembered some garage junkie who part owns a workshop around Sunway area told me this.

The items in which the car manufacturer gives you are actually the best there is and everything is tweaked to its optimum performance including the prescribed air filter in which will provide you with the best fuel consumption against acceleration. Any changes in either one of them would affect the balance. Thus:-

"increase air flow = more fuel burn = more power = increase fuel consumption"

The engine cannot be generating more power from air.

Another misconception some car modifiers have is that they thought by installing bodykits, it will increase the aerodynamics of the car hence reducing drag therefore better performance but little that they know, the weight these bodykits actually contributes actually cause more detriment to anything especially to those who installed super huge wings at the boot which is generally used to generate more down force to keep the car at the ground rather than making the car fly -.-

i do the same thing as you start to move when the cold indicator turn off, but my car didn judder, a "clark" sound will produce from the back and can be heard clearly inside the cabin. Only happen on the first start.

If engage to D and hold on the brake for few sec and pedal, the "clark" sound will not produced   

Same here. Have to press the pedal harder if u want to pick up faster. The car is like doesnt want to move. LOL

Had another run through the weekends. Driving work+ going back hometown+ jalan jalan+ back to shah alam. Avg 18.3km/l . it's doable with control footing , and off course traffic too

Wat type engine oil that u using? Semi or fully? Mineral?

i drive this car about 4 years plus, maximum i can go also 450km until the range become 0. how u all manage to achieve 500++ by the way i am all the time fully syn and light footer

Because it's new. Wait after 2 or 3 services then see how the FC.

Same here, dont understand how you guys get so good FC. I already try lightest foot possible on the pedal. But havent pass 5k service yet. Will see after that.

Anyone here encountered that the L15A i-VTEC engine emanates a  light gas blowing sound after the engine has been switched off after travelling for like 30 mins?
