Sure. It is stated on your hood and also service manual, Mach 5 mineral oil is recommended minimum. And it is approved for use to 10000KM without invalidating warranty.

yeah it was quite loud sometimes, could be suspension but quite unsure. will send to sc this weekend to check.

is it the foldable rear seat doesn't lock properly?
my previous is like that, need close it very hard.

RTFM bro,Mach 5 can be use on CFE, some of SC allow it to be use up to 10k km, some of it 5k km, its depend on preference, if your car rarely use, like 5k km need 3-4 month plus to reach, better use Mach 5, value for money. CFE engine tested/develop by Proton using Mach 5 which running for 15k km without any problem. manufacture try to use the lowest grade of EO to test out their engine.

the semi oil can tahan for 10k then?

upper trim near dash or near door latch?
you can open the whole panel, slow a form tape on it.
i did that for both front door, basically killed the sound. but i have random rattling a front passenger door when idle. the sound is there even without whole door panel.

it can~

Well, that is surprising Proton allows a 10,000km service interval for a mineral oil. Have you used the Mach 5 for 10,000km service, and if yes, which service centre allows that? Seems like double-standards as COSE does not even allow Synthium 800 for the Preve Turbo but Synthium 1000 as a minimum instead.

You can use any oils up to 10,000km service interval if you wish, even mineral oils. The only thing is service centres will establish the service intervals for the types of engine oils used in order to have the warranty intact.

Mineral oils in most cases are used for 5,000km intervals. It's the first time I got to know that Proton allows a 10,000km service interval for a mineral oil.

In order to keep the performance of the car at an optimum level, it is usually advisable to lower the change interval of all types of engine oil, full-synthetic, semi-synthetic or mineral oil. Ideal change interval for semi-synthetic oil is up to 10,000km, but you can still drive the car past this interval if you wish to. For semi-synthetic, recommended change interval is usually around 7,500km to 10,000km.

IN summary, it is the SC that will set the service interval to keep the warranty intact. In answering your question whether a semi-synthetic can "tahan" until 10,000km, it surely can. Even up to 15,000km if you want to do so. The question is whether the SC allows you to do that just to keep the warranty intact. The other aspect is stretching the change interval is not doing the engine too good.

yes i think it came from the foldable seat, thanks i should try to slam the rear seat.

Perodua semi-syn can have 10K KM service interval and still keep the warranty. Wonder why Proton insist for more.

My question is, can you keep you warranty with semi-syn oil doing 10K KM interval? Thank you in advance.

Why we need to depend on SCs whim and fancy which are inconsistent to say the least. Can't Proton set one standard for all SC to follow?

I'm seriously looking to get myself a Preve (preferably CFE), but these inconsistencies on whether or not customers can keep their warranty is just putting me off.

I'm confused now. Can Proton just come up with a single set of rule for all SC?

I use semi-syn oil (Syn 800) for my 1K and 10K service at Seksyen 13 PJ and Senaxis SC. Both said that the semi syn can last till 10K and yes, it will not void warranty.

Previously we can use semi-synthetic oil (Synthium 800) for the Preve Turbo. I was given this semi-synthetic engine oil during my 1,000km, 10,000km and 20,000km services. Only recently when I sent my car for the 30,000km service they informed they don't recommend the semi-synthetic (Synthium 800) for the Preve Turbo anymore after they found out some issues with this oil, and so I was given the full-synthetic (Synthium 1000).

Not too sure if it is true story or not, that the Synthium 800 semi-synthetic is not suitable for the Preve Turbo. I was charged RM502 for my 30,000km service and had sought an explanation from the Customer Service since last month but didn't get any response from them. I just called them up this evening to inform on my three(3) unattended emails to WeCare(Customer Service), and the lady on the phone informed he will get someone to call me. I will just wait for the phone call.


I can see that this is a problem or issue that is currently happening with Proton, inconsistencies not only with different service centres but the fact that the Mach 5 engine oil which is a mineral oil is approved by Proton for a 10,000km service interval, mentioned by someone here. I don't think there is any car manufacturer or service centres other than Proton that will allow a 10,000km service interval for a mineral oil. Since the service guy at COSE did not allow Synthium 800 to be used on the Preve Turbo anymore, I doubt the Mach 5 can be used, and what more up to 10,000km service interval. If it is 5,000km service interval then that is more like it.

That news that Syntium 800 is not supposed to be used, it something I have not heard of yet.

I might be having outdated news for using Mach 5 for 10000KM. Let me try to check with Proton, which I have already made an appointment to go 2 weeks later.

Do keep me updated, thanks. If it is proven that Synthium 800 can still be used for the Preve Turbo, then I am quite sure that my 30,000km service would not have cost up to RM500 but less. That particular service guy that was attending to me must be up to something.

get other car if can

Have anyone using

this Android player? How is the quality? Wanted to buy one.

noob question here

is there a way to rewire the Preve Auto fold mirror to make it like Suprima S?
when locking (fold in), unlocking (fold out)
instead drive at least 10-20km/h to fold out.
