Hi, Alexei,
Remember me about the Turbo die at 67K km? From the painful experience, I learn
(1) Don't use fully synthetic for 10K, it is best last for 5K only. For your information, my engine oil is Shell Helix Utra at 9+K when turbo die.
(2) In future I will use semi synthetic for every 5K, not more than every 3-4 months.
(3) To check and clean your engine oil pipe to turbo if you are not pratice number (2) above. 1st batch pipe may be smaller (not sure-need confirmation)
(4) Consider to use engine clean up treatment just before change engine oil at reasonable interval.
(5) Consider to change exhaust pipe to direct heat from turbo unit (not sure- need more study)
I can't reveal some of the information, if U follow above, ur turbo unit can last longer
Really thank you for taking the time to share your experience. My mileage is halfway there, would want to do anything within my power to prevent it from happening. Can you PM me those sensitive information that you can't reveal? It's ok if it's personal and I don't need to know.
To be honest, I disagree with you. On #3, the oil pipe size, it that should not matter because it is the oil passage internal to the turbo that cooks engine oil, not the oil line that supplies oil to the turbo...
My car just done 30k. First 1k oil was unknown, 2nd oil is Syntium 800, 3rd oil is Syntium 1000, and 4th oil Helix Ultra.
The turbo that EB use, the KP39A is very established in VW Turbo Diesel since 2005, I have read a few things here and there. Basically, it is a must to use fully synthetic. According to VW service manual, it is good for up to 16k km oil change interval. In other words, for VW TDI engine, as long as using fully synthetic that certified VW502 or better, it can last that long.
Reference:
2006 VW service intervalWhat oil to use for Jetta engines...For your case, what were the oils used before switching to Helix Ultra? Turbo or engine failure can be problems built up over time. If it is sludge, it is formed immediately, and also over time, under heat, engine stress and many other factors. Engine oil needs to have good sludge control. If you use semi-syn, or oil with poor sludge control, eventhough the change interval is short, the sludge will still form. Changing oil more often, vs using a good oil for longer interval, I choose the later. Also, sending to Proton for oil change is bad for wallet. They charge RM60 for labor.
One page I read about poor engine design, specifically dealing with Turbo engines, is using any oil other than fully synthetic, can cause dramatic sludge build up, and clogging up the turbo oil line and causing it to fail. Source:
Engines to avoidAnother thing about oil is, P1SC is giving out older packing Syntiums, which are only API-SM certified. Although it is recommended by Proton service manual, but, at that time, API-SN is very new. Newer Syntium have qualified for API-SN, but not sure if there is any change in formulation or not. The thing about API-SN over API-SM is that, it includes ILSAC-GF5. GF-5 specifically tests for sludge control, among other things. Later, API-SN incorporates ILSAC GF5. If you want more info, can look up how the test method for ILSAC GF5. In other words, anything less than API-SN, or ILSAC GF5 is not suitable for CFE.

ILSAC certificationsNow, ILSAC GF6 is under draft, and focuses on more interesting things that affects our cars...
I just want to share my thoughts and knowledge, no mean to offend you.
If you think I'm wrong, feel free point it out.
