General rule of thumb for oil change, 10,000km or 6 months, whichever comes first....

So even if the mileage is not there yet (4,000km) the oil would have started to break down inside the engine and will start to lose the lubrication properties, so its advisable to change it if you have reached 6 months...

You can always opt not to change at 6 months on the dot la... one more month (or two) may not harm the engine that much, it could always be marketing ploy by the oil companies....

But... saving RM200 for one two month later then change, versus the cost of engine.... i say change at 6 months....

Your choice....

Right.... so i need V1.2 oso.... maybe you can adjust the Mivec timing back to match K3 beta (wafark V number is this, so we can be really clear) to offset the throttle response??

Hang on....

Recommended using semi syn (S800) schedule = 1,000km -> 5,000km or 6 months after 1,000 (whichever comes first) -> 10,000km or 6 months after 5,000 -> and so on...

Recommended full syn (S1000 or S3000) schedule = 1,000km -> 10,000km or 6 months after 1,000 (whichever comes first) -> 20,000km or 6 months after 10,000 -> and so on...

I would NOT follow Proton's schedule of 10,000km intervals if using them semi syn S800, esp if you do plenty of short stop start drives, like morning jam to office, park till lunch, then park till jam back home type drive.... like in your case...

You should inform the SC when you register that they must not remove the K&N filter, so they remark it on the service sheet....

And stick the "Do Not Remove" sticker very near the K&N filter or at the air filter box, so that they dont "accidentally" remove it and blow air....

HSK was in shackles that day la....      me car had only two person, me be driver, navigator AND hunter.... lucky still manage to get 2nd place....
