Hello everyone. I am new in this forum & this is my 1st posting. I own a Proton Waja (Campro, 2006). Since the warranty has expired, I do the minor service at ordinary workshops, but the major service is still done at Proton Service Centre.

The main reason why I do minor service at ordinary workshop is because of the very long queue taken at big Proton Service Centres. Initially I went to an ordinary workshop empty handed. However that workshop tried to sell imitation white colour oil filter with Proton logo to me while trying to change the engine oil. I told the tauke that all this time I only see the blue colour oil filters at Proton Service Centre. Then the tauke claimed that Proton has 2 colours for genuine oil filters, which are blue and white. I told the tauke that I would like to have some time to think & will come again next time (but I didn't come). Few days later I went to Proton Service Centre to double-check whether the 'so called' genuine white colour Proton oil filters really exist or not. The workers at Proton Service Centre replied "mana ada?" while laughing at me.

From that point onwards, I bought genuine oil filters at Proton Parts Centre (or Proton Service Centre) & engine oil at petrol stations for minor service, then ask the worker at a tyre shop nearby my house to replace for me. If the tauke at ordinary workshop can try to cheat on me by selling imitation oil filter, I'm afraid that the engine oil sold at their place might also be imitation. So far I bought engine oil at Shell and BHP petrol station (all are semi-synthetic, 10W-40). In the future, I would also like to try Petron & Caltex engine oil (semi-synthetic, 10W-40).

Since the tyre workshop that i go is situated in city outskirt (Kampung Melayu Subang), the tauke only charges me RM10 for engine oil & oil filter replacement. I will consider to replace myself if the price goes higher, but I need to consider where to disposed the old oil properly (without harming the environment).

There was also 1 time I brought my own genuine oil filter (that I bought from Proton Service Centre), but decided to use the engine oil sold at the ordinary workshop. That workshop sold Liqui Moly engine oil. After replacing the engine oil, I notice that my engine pick-up became slower than usual, plus my engine sounded noisier than usual. I suspect that the Liqui Moly sold at the workshop is a counterfeit product. After that point onwards, I never go to that workshop anymore. My friend told me to try Liqui Moly again from another source to verify about this, but so far I have no idea where to purchase Liqui Moly from trustworthy sources.

Since there are too many items need to be replaced for the major service, I still send my car to be serviced at Proton Service Centre. After the imitation parts incidents (oil filter & engine oil), I don't want to take the risk of purchasing imitation parts for major service.

Beside the engine oil that are sold at petrol stations, I would also like to try the other brands (semi-synthetic, 10W-40) that are sold at trustworthy sellers, such as Tesco & Eneos. Some of the brands that are sold at Tesco & Eneos are:
1) Mobil
2) Castrol
3) Repsol
4) Elf
5) Total
6) Tesco brand itself
7) Pennzoil
8) Eneos brand itself
9) Bardahl
10) Eni
11) Prince
12) Q8
13) Aurotech

Hi all,
I've been buying branded EO from Tesco for years. Just came back from one continental shop in Bertam, Penang. The mech said that the same brand and SAE EO from Tesco is different with the similar brand bought from petrol station. I didn't argue with him. But I prefer to do some homework here for the next time I meet him. 

Here is my EO that I bought at Tesco last year for RM 199.



It said clearly that the EO is 0W40, MB-Approval 229.5/229.3, API SN/SM. If anyone is wondering, EO has a shelf life for 5 years.

Can anyone that use the same brand, same spec but bought this EO at petrol station/workshop that people said it is GENUINE post the EO pictures here? Just want to compare.

For info, this is my car's EO spec:


MB-Approval 229.3/229.31/229.5/229.51

There was someone in this thread that post about the API of the Tesco bought EO that is not in par with Malaysian standard. Do you see the above picture? It is API SN/SM. What is Malaysian standard? SO? SP? SZ?

Without discount/promotion, this EO cost around RM250 - RM27x if I'm not mistaken. I firmly believe that any branded EO at Tesco is genuine. But, I don't want to try Tesco's brand in my car. I always stick with car's manufacturer requirement.

One time, I brought my car to a workshop and the mech have a quick peek under the engine cover and he surprised that the top portion of my engine is very clean and not look like an over 10 years car.

For performance, morning startup is easy and smooth. There was one time I tried 5W40 EO and I wasn't satisfied with the smoothness. It was Shell if I'm not mistaken.
