Too bad I didn't learn of your thread when I had my Camry hybrid.  Would be nice to compare the blotter.  Generally at 10k KM oil colour is lighter colour then my 5200km one.

Speaking of Hybrid, here is a 3262 km Toyota 0W20 blotter from a Gen 3 Toyota Prius at Odo 180k km, courtesy of @abubin .

I haven't really 'read' much on UOA's of hybrids like Toyota's, but I would speculate a hybrid engine oci's could easily be further extended by a factor of say, 1.3-1.8 times that of non-hybrid siblings, for quite similar wear particles count in ppm per 10k km or miles.

Basically Factory recommended oci's of Asian engines are very conservative with plenty of margin, imho.

Edit:
Attached below is a low'ish 5136 km UOA of Idemitsu Zepro Advanced Moly 0W20 in a 2011 Toyota Prius Hybrid 2ZR-FXE 1.8L Odo 304k kms .
Look at its impressive low ppm count of wear metals with a residual TBN of 6.2!

Based on the 30% fuel economy for Toyota hybrid, my estimate will be 30% more mileage for engine oil. So agree 1.3-1.8 times is achievable.

Hi Zeng bro,

2016 Estima 2AZFE 53700km
Oil brand unknown, recond dealer changed it.  Most likely mineral oil as the sticker show change after 5k.
Oil mileage 5200km
I had added about 20ml of Toyota engine flush at 52500km.
After that my per trip fuel economy range 11+km/L to 15km/L.  Before was at 11+ KM/L to 12+km/L.  Oil colour is slightly darker now. 

I am planning to change it to Toyota synthetic formulation 5w30 soon.  And 60k km change to full synthetic.  I have recond warranty so will need to follow the 10k KM OCI.

Thanks for your input.

Walaooo.... super high Moly and Boron counts. This oil is really geared to fuel economy. But dont think this EO is available officialy in Msia.

Hi Bro,
The very dark black 'dots' in a triangular shape looks a bit odd to me as a proper blotter is typically round or circular in shape.
Before depositing the blotter, did you make sure the paper was clean and white and the dipstick was not touching/in contact with the paper?
What's is size or length in mm of the 3 sides of the blackish triangle in its original form/sample as kept by you?
Wish you could throw some light on the blackish triangle things, assuming proper steps in depositing the oil drop onto the paper has been taken by you.

Yes, Mo and Boron are good for fuel economy as their compounds are basically friction-reducing in nature.

They are sort of solid lubricants thickening up the Minimum Oil Film Thickness at the same time generating relatively lower oil temperature assisting lower viscosity oil grade to withstand better in high stress areas in cam lobes etc.

Besides, Boron performs additionally as an oil detergent/dispersant too.

Hi Bro,
It is somewhat odd to me as well. I had collect it myself and didn't see it on the paper before.

Doing another blotter today. Will see how it goes. Hopefully nothing to do with the fiber balance shaft breaking down.

Ahhh.... Bro that makes some sense that the blackish stuffs may be potentially of fibre material, who knows?

Ok, for now let's make the assumption that the blackish particles is 'foreign' and not part of the emulsified oil sample from which you took blotter spot test samples.

Other than the blackish 'foreign' particles stuff, the Centre zone is transparent and not darkened which means there is almost no large size or heavy metal wear contaminants within the oil sample which is good news.

The slightly 'clearer' second blotter picture here of 6000 km usage (compared to previous first blotter picture posted on Oct 7) points vaguely to the very preliminary stage of potential emergence of increasingly darkened aureuol zone/perimeter ring.
Fact is the slightly darkened aureole zone has not formed, yet!

This is something important for us to monitor for the eventual possible formation or emergence of (very) darkened or greyish aureole zone/perimeter ring with continuing use of this 6000 km Castrol 20W50.

The Diffusion zone is clear and transparent, clearly pointing to the negligible or very low levels of fine size contaminants or combustion by-products within the oil sample.

There is absence of darkened zigzag jagged edge at the outside edge indicating absence of moisture and/or absence or low levels of oxidation phenomenon, which is really good news for a mineral oil at 6000 km usage.

Very slight halo phenomenon at the outermost zone pointing to some very slight amount of fuel dilution in this 54.5k kms 2016 Estime engine.

Overall I think this 6000 km Castrol 20W50 mineral oil is fit for continuing use if you do desire, as I believe the detergency and dispersancy properties of the used oils are basically intact unharmed and there is very little oil oxidation if any.

On fibre balance shaft in an Estima .......


Note: I would estimate the size/lengths of the 3 sides of the 'blackish' triangle as about 2.5mm X 2..5mm X 1.5 mm in the real physical sample. Is the estimate off?

Bro Zeng, good estimate. Actual is 0.5mm bigger at 3mm x 3mm x2mm. Subsequent blotters are clean and looks similar. I tried to drain some oil as it is overfilled and I found bubbles when checking dip stick. Unfortunately the drain plug dropped in the oil and I end up draining the whole pan. So ends of this oil use.

My initial blotter at 53k there is something that looks like metal bits. But it fell off the paper as I was shuffling between other papers before 48hr.

Hi Bro,

For a very short usage 1172 km blotter spot test of a fully synthetic 5W30 Kaito oil, the degree of greyness/darkness indicates a rather poor blotter spot performance.

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.

Just my 2 sen.

Thanks for the detailed analysis. I have since done oil flush and changed to another old which I will use for maybe 1 month. This is to clear the engine from the harmful engine flush that may still linger after the first flush.

Bro Zeng...... this is SHU 5w-40 API SN from Giant.

Done 12.6k kms. Used on Elantra 2.0 NA (G4GC). Pic shows 48hrs blot, sample taken hot.

Last service 05 Jan 2021, drained out 16 Oct 2021. Took 10mth to reach 12.6k km due to MCO. Piled up around 6-7k km during the 1st 3mth coz still can travel. MCO came in Mar 2021 and all were down to short distance drives to buy groceries. Then travel resumed from end-Aug till drain out date.

Appreciate your analysis.

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 laugh.gif 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. laugh.gif

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).

For more information on Daimler MB229.5, contact your Lubrizol representative.

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

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?
