Wow, clean and transparent blotter at 10094 km with complete absence of shade of grey colour in the centre zone, the perimeter ring and clean and yellowish diffusion zones .
Another achievement is the seeming absence of signs of water moisture , which I consider as exceptional after having gone through numerous blotter spots .
Personally, I would carry on with this oil up to a minimum of 15000 km , probably more .

Thanks Bro Zeng for the details
Will try to drag untill 12k then will post again the results
So far oil level no changes
But performance wise that acceleration quite draggy

Performance at 10000 km becomes quite draggy , despise potential drop in operating viscosity due to breakdown of Viscosity Index Improvers VII aka viscosity-shearing ?

Am I surprise here ? Not quite really , to the extent you could 'feel' the difference ,if any .

Has this 10000 km gone bad ? Maybe , as compared to virgin new .

Is this 10000 km used oil too 'old' and no longer provide components protection,detrimental mechanically and hence unfit for continuing service ?

I don't think so . In the absence of 'expensive and messy' Used Oil Analysis , your 10000 km blotter spot suggests it is fit for additional thousand(s) of km IMHO , never mind the fact that you may have exceeded the 10000 km OCI (?? ,IDK) recommended by OEM .

Note:
This HX8 X 5W30 contains some Molybdenum additive whose Coefficient of Friction in application potentially increases with use in your context .
Hence your 'feeling' of being draggy ?

Wow hx8 so nice. Value for money!

Note that hx8 x and hx8 is different

To support my contention above , attached below is a chart demonstrating the phenomenon of
increasing engine Coefficient of Friction,
with decreasing ppm(parts per million) of Molybdenum additive ...
in a typical engine oil application which likely applies to this application of HX8 5W30 of voa Molybdenum 39 ppm .

repost here.

daikor zeng, tolong...

which one better? I want to get to for my next engine oil test.

hx8 x better i guess. i no expect.
but hx8 is only SL spec.

Any promo currently at hypermarkets fot hx8 x? Want to get 2 bottles.

hypermarkets only have hx8 la
but i dunno got promo or not now. nowadays the promo always run together with shell helix ultra 5w40.
same price punya.

Sure , your pleasure .

The Centre Zone of about say, 8 mm has not heavily darkened and became opaque, hence it has not formed yet from the agglomeration and coagulation of combustion products .

The Perimeter Ring of about say, 10 mm annulus ring surrounding the Centre Zone has not formed or visible with darkened colour.

Both the above shows no trace of agglomeration and coagulation of combustion products in this Urania LS mid-SaPS HDEO at 5000 km .

The complete circle of Outer Diameter 20 mm of light grayish colour indicating quite an even distribution of all the dirts and contaminants of combustion .

Exterior to the above 20 mm OD circle shows light yellow colour and looking transparent, indicating very low level of contaminants and dirts in the used oil .

Overall, this blotter spot indicates the detergency and dispersancy properties of this 5000 km used oil is still in tip top condition . IMHO it is still serviceable for another several thousands of km .

Btw, this mid-SaPS Petronas Urania LS 15W40 has a very powerful specs in CJ4/ E9 etc .



Note:May I know the (petrol) engine type in use here and its current odometer readings ?

thanks for reposting here

Engine campro vvt, petronas ron95, current odometer 60k

What your comment on normal car using hdeo?
btw i use this car for street race,little modified here and there, sometime redline till rev limit, gearbox manual

I have been using HDEO 15W40 in my wira and Avanza for many many years .
HDEO's are fine for non-Euro petrol engines, IMO .
CJ4 HDEO's is smart selection in your 'harsh' context , and you appear to be well informed .

Note:Lately I switched to readily available semisyn and fullsyn 'PCMO' Euro oils for its frequent promotional price .

zeng, what is the km interval for this oil? interested to try this out !

Before semisyn and fullsyn, I have been on Petronas Supremo CI4 15W40 for several years at up to 9000 km .
This 3000 LS is mid SaPS in CJ4, which is slightly higher spec'ed than my previous CI4 .
Personally, I have no qualms going for 10,000 km oci or more and comfortable about it .
Your comfort level may vary though .

Any comments on the Syntium Fully Synthetic 3000 series 5W30 oil?

If you mean the local Petronas version of Syntium 3000 series 5W30 , it has stronger spec (than SN/SM) in Dexos 1 Gen 2 .
GM approves this oil up to 10,000 miles (16,000 km) oil change intervals in States .

If you mean this imported Petronas Syntium 3000 FR 5W30 , it has stronger spec (than SN/SM) in Ford 913D specification .
Ford US too approves this oil for up to 10,000 miles (16,000 km) oil change intervals .

In Asian/US engines, use these 2 oils with peace of mind even with above stipulated oci .
