Mechanical conditons of this 2006 Myvi auto engine and your driving styles may also contribute to this relatively poor blotter performance. The Centre zone is quite greyish though remains transparent indicating substantial amount of large size and/or heavy metallic wear contaminants for a lowish 1172 km blotter. Emerging darkened aureole zone or darkened perimeter ring too could be observed indicating the oil sample has commenced agglomeration at this early stage. Diffusion zone is transparent but relatively greyish pointing to quite substantial amount of fine-sized contaminants for its low mileage, imho. There is absence of darkened zig-zag jagged edge at the outermost zone, as expected for a typically low mileage blotter spot, points to near absence of moisture and/or oil oxidation phenomenon. External to outermost zone one can see clearly the all too obvious and large size translucent halo indicating a rather severe fuel dilution phenomenon leading to poor/high fuel consumption. Generally, I believe this 1172 km used Kaito 5W30 oil whose detergency and dispersancy properties still remains intact and thus is fit for continuing use imo whilst keeping a close eye on formation of darkened aureole zone/ perimeter ring.

This is to clear the engine from the harmful engine flush that may still linger after the first flush. zeng liked this post

Hi Bro, As suggested by e-lite above, this Elantra 2.0L NA seems to be very well taken care of with a superb 12.6k kms clean blotter spot. There is absence of greyed centre zone which is light coloured and transparent indicating very low levels of large-sized dirts or high density/heavy metal wear dirts at 12.6k kms usage. There is also absence of emergent darkened aureole zone/perimeter in normal blotter, although the second picture with lighted background light has 'exposed' the hidden and emerging aureole zone/perimeter ring which is lightly darkened. This indicates agglomeration of combustion byproducts is very mild and light at 12.6k kms usage . The Diffusion zone is light coloured and transparent indicating presence of very low levels of fine-sized contaminants and dirts indicating superb residual detergency and dispersancy oil properties. The jagged zigzag edge at the outermost zone has emerged in shape but they are not really darkened , yet (unlike my 12k km blotters in general) indicating very low levels of oil oxidation and/or moisture content which I consider as harmless. Besides it may indicate your engine may be quite free of varnish. No, I'm not refering to sludge. Whilst it is hard to identify translucent halo outside the outermost zone, the second blotter with backlight has 'exposed' beyond doubt its presence, indicating presence of 'undesirable' fuel dilution phenomenon but remains harmless for now imo. Overall, I believe this 12.6k SHU 5W40 is still in good working condition and is fit for continuing use for thousands of kms to come, more so in this well maintained Elantra 2.0L NA. Just my 2 sen. Edit: The undarkened emergent jagged zigzag edge at the outermost zone may indicate very preliminary and light levels of oil oxidation phenomenon meaning its residual anti-oxidant property is superb and intact imho.

Thanks Zeng for the analysis. Can't continue to use that oil anymore coz already drained it out Sample was taken right after a 350km outstation drive. I think this should clear doubts over the authenticity of SHU stocks sold/selling in Giant hypermarts. Which will also mean more people will compete to buy and less chance for us to get. zeng liked this post

Hi Zeng. I think I've found the minimum spec for MB229.5 oil. Daimler MB229.5 MB229.5 oils are Upper Mainline high SAPS¹ lubricants designed for use in high performance gasoline and light duty diesel engines without advanced aftertreatment systems such as Diesel Particulate Filters (DPFs). MB229.5 oils are typically SAE 5W-40, 5W-30 or 0W-30 based on API Group III or a mix of API Group III and Group IV base oils. The main physical and chemical requirements for MB229.5 are shown below: Requirement Method Unit Limit HTHS viscosity at 150°C CEC L-36-A-90 cP ≥ 3.5 Sulphated Ash ASTM D874 %wt > 1.0 and ≤ 1.6 Phosphorus ASTM D5185 %wt ≥ 0.05 and ≤ 0.11 Sulfur ASTM D5185 %wt ≤ 0.5 Evaporation loss (NOACK) at 250°C CEC L-40-93 % ≤ 10 Total Base Number ASTM D2896 mgKOH/g ≥ 10.0 Note 1: SAPS refers to Sulphated Ash, Phosphorus and Sulfur, the levels of which are often restricted in the latest performance specifications. MB229.5 is usually coupled with a range of different combinations of other approvals depending on the viscosity grade of the lubricant. The most frequently seen approvals claimed in conjunction with MB229.5 being ACEA A3/B4, BMW Longlife-01, Volkswagen 50200/50500, Renault RN0710, Renault RN0700, Peugeot B71 2296 (5W-40 only) and Porsche A40 (5W-40 only).

The odo now is 133k not 134k as i previously mentioned. And its been 5 months and 1 week simce my last service at 130k km. Curious to know if i can still use it until 140k km or at least can drag to 9 or 12 months. Im not sure what is the black dots on the oil spot but this paper is not a new paper, it is a used paper and already printed With a bit light at background QUOTE(zeng @ Jun 6 2021, 01:45 PM) Hi Bro, Thanks for uploading these 48 hour blotter spot tests which I believe have kind of 'matured' and are not having vastly evolving changes with time, in the image. Basically these blotter spots are lacking in undesirable 'structures' .......... meaning the used oil conditions are in top form with plenty of life to go. Centre zone (of about 8 mm diameter size in real sample) is not darkened and is clean and transparent, which is good news as it indicates very little or negligible amount of heavy and/or big sized contaminants/dirts being present in this 3k kms 5 months 5W30 sample. There is also absence of darkened aureole zone/perimeter ring indicating the oil's detergency and dispersancy capabilities and properties of the used oil is intact and in top form. Besides , there is absence of coagulation of contaminant particles which is good news. Diffusion zone external to 'perimeter ring' (which is not darkened here) is light coloured and transparent showing very very low levels of combustion contaminants/dirts. Darkened and jagged edge outside of Diffusion zone is absent , indicating absence of undesirable water moisture content in this 40-minute operation hot oil. At the outermost zone, there is some slight appearance of translucent annulus called halo which indicates mild level of fuel dilution phenomenon in this hot blotter sample, which remains harmless for now with very little contaminants/dirts in this 3k kms 5 month used oil sample. Overall IMO there is a lot more oil life to go on and this used oil is fit for continuing service. Can this used Syntium 5W30 continue to be in operation till Odo 140k kms, meaning a 10k kms oil change interval or 12 months use in Campro ? Well, I believe this Syntium 5W30 should perform well till then whilst you may continue to take blotter spot test say, at 6000 km and 9000 km mileage with a view of establishing the possibility of 10k kms oci, at a level/mileage comfortable to you. Don't worry about the 'black dots' you mentioned as they are merely 'imperfections' in sample taking on a used/old A4 sized paper and it doesn't distort the 'reading' of blotter spot. Hi bro. Im back after 5 months plus from last spot blotter analysis. So this is spot blotter 10.5 months after my last service using Syntium 3000 5w30 fully synthetic. 136000km total mileage. Which means 6000km after last service and 3000km after your last analysis. Appreciate if you can do your amazing analysis. Thanks bro. Edit: this spot blotter was taken after a 270km non stop 4 hours trips a week ago.

Got no time to write to you until today With little light at the background: Hi Bro, sorry for the slow reply and thousand apologies. This is a superb 6000 km blotter spot with total absence of 'structures' demarcating the various zones of this 10.5 month used oil which is a good news. The Centre Zone is generally clean, light coloured , transparent and not greyed or (slightly) darkened indicating very low levels or absence of heavy or large size insolubles/combustion contaminants within the sample. There is also obvious absence of greyed/ slightly darkened aureole zone/perimeter ring indicating absence of agglomeration of insolubles/dirts probably due to very low levels of contaminants within the 10.5 month used oil sample. Diffusion Zone is generally very clean, light coloured and transparent indicating very low levels of fine-size or light-weight contaminats/insolubles. The above observations would likely give you a UOA (if you care to pay for one) of very very low ppm levels of metal wear element counts and insolubles content. Darkened jagged zig-zag external edge is absent from the blotter indicating very very negligible oxidation level of this used oil or absence of moisture content. At the outermost zone in the blotter sample with back-light 'exposes' the presence translucent halo indicating fuel dilution phenomenon. This fuel dilution phenomenon is sort of 'undetectable' from blotter spot test without back-light. Hence, a blotter spot test does have its limitations or inadequacies just like any other methodologies of used oil analysis, among others. Overall, I would consider this 10.5 months old/6000 km blotter spot as clean and good to go on for further use. Besides, the used oil sample/engine mechanical condition combo is in top shape although I'm actually a little bit surprise to having seen/found fuel dilution phenomenon in this blotter immediately after a 270 km/4 hour drive. Not sure whether a fuel dilution phenomenon in this Campro engine could be improved upon with engine (ECU) 'tuning' and/or application of injector nozzle cleaning fuel additives leading to improved fuel economy?

Thanks bro for your detail analysis. I am actually surprised about the engine oil conditiion. Is this also means my 136k km engine is in top shape? I kinda tortured this car in this 6+ years. Btw i have changed the oil to Proton 5w30 fully because of the fuel dillution marks worrying me. And like i mentioned before, this car been in idle for hours. Could it be because of that? Do you know the symptoms of dirty fuel injector? And any recommendation for fuel additives for Campro again?

And like i mentioned before, this car been in idle for hours. Could it be because of that? Do you know the symptoms of dirty fuel injector? And any recommendation for fuel additives for Campro again? Sorry, I am not aware this car has been subjected to 'long' idling hours which would definitely contribute to fuel dilution problem. Having said that, presence of a typical level of fuel in engine oils would have been 'evaporated off' during a long 270 km/ 4 hour drive, if you know what I mean. In this context, the idling hours and your driving style may have promoted excessively high level of fuel dilution to begin with well before this long 270 km/ 4 hour travel? If so, you should probably 'control' the idling hour duration of this engine to mitigate this fuel dilution phenomenon. Hence your injectors cleanliness may be ok and free... rendering the use of socalled fuel injector additives treatment unnecessary imho. Meanwhile for similar controlled price of RON 95/97 across all fuel/oil companies in this highly interventionist economy of ours, you may want to consider switching to BHP petrol fuel for its claimed (which I believe so) higher fuel additive content of 800 ppm (of German Technology origin) compared to other brands of like 400-600 ppm (???) without expending money on dedicated addtive treatments. Yes, your blotters suggest the mechanical condition of this Campro engine is in top shape if I may speculate. This post has been edited by zeng: Nov 17 2021, 09:32 PM

However the centre zone is not light coloured and truly transparent indicating quite a high levels of heavy high-density insolubels and contaminants in this 15,229 km blotter spot. It is a saving grace that there is absence of darkened aureole zone/perimeter ring indicating absence of undesirable agglomeration/glue'ing of insolubes/contaminants. This means there isn't signs of dirty deposits getting stucked/glue'ed onto contacting internal metal surfaces. The dispersion zone is generally darkened with rather extensive amounts/quantities of light density insoluble/combustion contaminants. The darkened jagged external edge indicates quite a high level of oil oxidation/water moisture in this 15,229 km blotter. There appears to be a possible translucent halo at the outermost zone indicating a certain fuel dilution phenomenon though it is not obvious. With back light, a translucent halo would be much more obvious. Overall this rather darkened blotter spot doesn't look pleasant and raises the need to caution. I wouldn't consider running this used oil beyond say, 17000 km and it is time to schedule next oil change at a convenient time. This post has been edited by zeng: Dec 9 2021, 11:44 AM

Thank you Hi Bro, There is a very light-coloured and transparent centre zone in this 12k kms Aisin FS Pao Ester 5W40 blotter spot indicating there is very minimal or absence of high-density heavy metallic insolubles or contaminants in the used oil. There is no sign of imminent darkened aureole zone/perimeter ring indicating absence of agglomeration of combustion dirts and contaminants. The diffusion zone is clean, light coloured and transparent indicating very low levels of light-density contaminants or soots despite its rather high mileage. At the outermost edge unlike most other >10k kms blotter spots, this 12k kms blotter doesn't exhibit any darkened jagged zig-zag external edge, even slightly, indicating very low levels or absence of moisture content and/or oil oxidation phenomenon reflecting top class anti-oxidation/detergency/dispersancy capabilities of this used oil sample. Translucent halo at the outermost zone is absent, indicating absence of fuel dilution phenomenon. This 12k kms blotter is comparable in performance against the other 12k kms blotter spot, also of an Aisin Pao Ester which together fares so much more better than most if not all blotter spots as found in Post #1 of this thread. Overall, imho this 12k used oil still has plenty of life to go on............. Bro, do note that this Aisin Pao Ester oil is a mid-SaPS (Sulphated ash Phosphorous Sulphur) oil formulation which I consider as generally superior and better than a typical high SaPS oils as commonly found in the market.

I was hoping that you can help to analyse my car's blotter spot test too. My car is toyota vios NCP93 year 2008, current car mileage is 241k. done top overhaul recently in may 2020 due to excessive engine oil consumption. currently for the blotter , im using Aisin FS Pao Ester 5W-40 , age of oil is 3 months, done 12k KM your comment is highly appreciated. Thank you Since you already overhaul the engine, you should use 5w30 oil instead of 5w40. I mean, unless you have tested and found higher viscos oil is better. Else 5w30 will make the engine run smoother and less prone to sludge.

There is no sign of imminent darkened aureole zone/perimeter ring indicating absence of agglomeration of combustion dirts and contaminants. The diffusion zone is clean, light coloured and transparent indicating very low levels of light-density contaminants or soots despite its rather high mileage. At the outermost edge unlike most other >10k kms blotter spots, this 12k kms blotter doesn't exhibit any darkened jagged zig-zag external edge, even slightly, indicating very low levels or absence of moisture content and/or oil oxidation phenomenon reflecting top class anti-oxidation/detergency/dispersancy capabilities of this used oil sample. Translucent halo at the outermost zone is absent, indicating absence of fuel dilution phenomenon. This 12k kms blotter is comparable in performance against the other 12k kms blotter spot, also of an Aisin Pao Ester which together fares so much more better than most if not all blotter spots as found in Post #1 of this thread. Overall, imho this 12k used oil still has plenty of life to go on............. Bro, do note that this Aisin Pao Ester oil is a mid-SaPS (Sulphated ash Phosphorous Sulphur) oil formulation which I consider as generally superior and better than a typical high SaPS oils as commonly found in the market. Just my 2 sen. Thanks for the detailed analysis much appreciated I'm using 5W40 all these while because of small leaks in the engine, causing it to "makan" engine oil, as expected in 1NZ-FE engine after 150k http://mywikimotors.com/toyota-1nz/ However, since the leak is minimal now after overhaul, Will consider 5W30 for next oil change thanks for the advice too abubin zeng liked this post

Aureole zone/perimeter ring is not about to darken/gray yet and there isn't any agglomeration of contaminants/soot of concern which is good news. Detergency and Dispersancy properties of this used oil seems to be in top shape. Diffusion zone is very bright 'white' and transparent indicating this 10,081 km diesel blotter has very low levels of light-density carbon soots and combustion contaminants. There is absence of darkened jagged zig-zag external edge indicating no severe phenomena of water moisture and oil oxidation. Translucent halo at outermost zone is absent indicating absence of fuel dilution problem in this diesel DI engine. The blotter indicates a very clean engine internal conditions which is normal in a 36k kms Odo engine. Overall, I'm of the opinion this Shell Helx Protect 0W30 SN+ A3B4 used oil sample at 10,081 km is holding up very well and it still has plenty of residual life left for further use and continuing service, if you're comfortable with it and mindful of 'loss' of warranty rights probably (Pl clarify with conservative SC). Just my 2 sen. Note: 50% tarmac and 50% off-road usage is considered as severe according to 'passenger' car manufacturers. However a Hilux is designed/meant for such use. At 10k kms usage, this blotter spot test indicates no issue. This post has been edited by zeng: Dec 22 2021, 07:43 AM Gin87 liked this post

New Member Probation 28 posts Joined: Nov 2020	🙏 thanks bro zeng. I've been servicing the car myself since after 2nd service at toyota, so warranty is out of the picture, hahah. It seems that the oil look 'cleaner' at 10k km compare to 5k km, I guess the oil 'cleaned-off' the residue from previous different spec'd oil. zeng liked this post
