Guys, i just done my first service.. (i opted for the 5 years free service during April), and the service center girl told me the engine oil they provided is semi synthetic which can only until 5k mileage.. and as for the free voucher for the 5 years free service are cover for each 10k mileage only, the girl asked me to come for service on next 5k mileage and i need to pay myself on the service..
As a first time own a proton, i didn't know that actually the semi synthetic oil actually can run until 10k (which the HQ CS claimed so), and i buta2 asked for upgraded to the full synthetic oil to be 10k mileage and paid more than 100, which i don't want to pay for the next each 5k mileage service.. after service only i checked with Proton HQ regarding this, and they said actually the semi engine oil is able to use till 10k mileage..

Really disappointed with the service center didn't explain clearly, and what they just want is to earn more money from the customer..

For the first owner of proton, please check clearly first before you do your first service, check with HQ before agreed on anything.. dont be like me...

Technically, semi syn oil best change at 5k- 7k.
Why Proton let you go back at 10k interval because the computer is already fixed to reset at 10,000km, cannot set to 5,000km So no matter what oil you use, is 10000km. Some service centre will do this: if they see you use semi syn they will give you another sticker to stick on your windscreen and ask you to come back at 5k. Actually they are good because semi-syn is really not designed to last long mileage. And if you tested the semi and fully in Persona, you will know the difference. Car is heavier in semi.
After my first service with fully syn, it was quite ok, then i decided to use my preferred oil on the second service. So on the second service, i ask for semi syn (since the counter told me it's 10,000km anyway because they can only set 10k in the computer regardless semi/fully) . I drove about 1000km on the semi syn and I already start complaining. I drove to a service centre outside, ask them to suck the oil out without touching the oil filter, then i change to my preferred oil. Drive becomes so smooth after that. No complaints now.
I wasted the RM100 semi syn oil but i don't care. I use my car everyday and i don't want to complaint about it.
