An 'ugly' 15600 km blotter spot from Russia ,
do you think it is good to go on ??

Hope you can share with us here the end of life blotter spot , as part of learning .

Hi,
As someone commented above , this blotter spot is very clean and clear .
There is absence of dark centre zone and perimeter ring .
Very little combustion contaminants and dirt .
No sign of fuel dilution and water moisture .
IMHO, this HX8 is good to go on further .

Hi,my comments on 6279 km blotter generally still applies in this 8168 km HX8 5W30 .
Total absence of dark coloured perimeter ring and centre spot/zone .
Duffusion zone has not a shade of grey colour , indicating very very low levels of contaminants and dirt .
I think your engine is super clean to begin with , meaning you had previously very short oil change intervals and consistently well maintained by you .
You may compare this clean 8168 km blotter against other 8000 - 10000 km blotters on post #1, and I would be personally confident to go on for many more thousands of km .

Hi Chemistry,
Wow , fuel dilution seems indetectable this time round compared to previous 9771 blot which is good news with this carburrettor engine .
Yes, the shade of gray colour diffusion zone is slightly darker than before but it remains harmless IMO , because of the absence of darkened and opaque centre zone and absence of darkened perimeter ring .
Generally the contaminants (though slightly higher than 9771 km) has not coagulated into insolubles or semi-solubles and it is well dispersed .
Slight moisture is present , which does not render this used oil unfit .
IMO, this semi synthetic Mannol is still serviceable at 11000 km for further use .

Yeah, it's very hectic close to CNY .
I had done 8000 - 10000 km with Petronas CI4 15W40 in Wira .
Notice the hugh capability of this Mannol HDEO in its detergency and dispersancy property in this 11000 km blot spot , in relation to PCMO's generally .

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 .

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 ?

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 .

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 ?

Thank you, for your feedback .

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 .

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 .

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 .

Hi 90Boyz,

Thanks for sharing .

There is no sign of fuel dilution problem , as seen from the absence of outermost translucent zone/annulus .

There is also absence of darkened centre zone (of about 8 mm diameter) and absence of perimeter zone (of about 10 mm outer diameter OD) ,which are good news, probably due to a very low level of combustion contaminants and still-high performance levels of detergency and dispersancy of the used oils .

The very slight grayish and light colour of the Diffusion zone indicates very low level of dirt/contaminants after 11,933 km usage , with very high level of residual detergency/dispersancy capabilities of the used oil .

I would speculate the internal cleanliness of this 2009 Honda City engine is very clean and /or this HX8 5W30 is performing in top shape/form ,or both .

IMHO, this 11,933 km used oil is still serviceable and fit for continuing service .

Yes, I'm aware you'd replace the oil with Amsoil which is another good (but expensive) engine oil .

Amsoil Signature 5W30 has a substantial and high amount of Molybdenum and Boron additives .
That probably helps with the bold above .

Hi,
Sorry, I'm incapable to tell its performance from virgin oil blotter spot which is form of qualitative test .

However this Long Life oil has super duper specifications and OEM approvals in VW 50400 50700 MB 229.52 ACEA C3 etc , if genuine .

The approvals carry with it OEM approved oil change interval up to 30,000 km in respective OEM applications .

Hi mate,

There is absence of darkened centre zone (typically of about 8-9 mm diameter) and darkened perimeter ring surrounding it , which is good news in itself .

The diffusion zone is very lightly gray indicating very low levels of combustion contaminants/dirt within the used oil .

It also indicates high capacity in detergency/dispersancy properties .

However, the translucent outermost zone indicates there is sign of duel dilution which requires monitoring in this 1020 km used oil .

Anyway this Helix Ultra 5W40 has very high specs in MB 229.5 VW 50200 50500 A3B4 and it has plenty of life to go on in your Vios , IMHO .

Assuming you are a beginner in oil blotter spot test, you may do tests at intervals of say 2,000 km to 'see' and learn the process of oil being 'damaged' or 'condemned' for further use .

Finally depending on your comfortable oil change intervals of 5000 or 8000 or 12000 or 15000 km , do another test say 1000 km before intended mileage giving yourself another evaluation seeking further opinion and most importantly, a bit of time to plan your next oil change date .

IMO, 5000 km oil change interval for a Helix Ultra 5W40 A3B4 or Syntium 5000 C3 5W30 is a bit too short for the Vios .

For folks who are comfortable with 5000 -8000 km oil change intervals, why not consider any mineral non-semisyn 15W40/10W30 gasoline or diesel engine oils . This position is based on my readings on various Used Oil Analyses so far .

Fuel consumption increases with Ultra 5W40 ?

I don't thick Syntium 5W30 C3 would help much IMHO if perceptible .

Why not consider upping your tyre pressure to minimum 36 psi as permitted by tyre manufacturers for better fuel economy ?

Just my 2 sen .

Edit: On fuel dilution problem, don't worry about it in your context of generally short oil change interval as it is rather academic than practicality IMO.
