My own GT86 back to back reports trying out new Valvoline SynPower Eco , next up, trying out MoS2! additives

some Q&A for my own samples:
1) Does wear in general increase exponentially? Reason for this is that my latest 2 samples did not run half as much compared to the previous Petronas, however the wear is indeed half in general.
Wear metals normally increase as the oil is run longer. Iron tends to change depending on the kilometers on the oil the most directly. Your iron levels on these two reports are indeed lower than the levels on the three reports before them, even when you divide the parts per million by the kilometers on the oil. In spite of the increase in spirited driving you mentioned on the information sheet with the sample, steel parts are truly wearing less than they had been.

2) This Valvoline is very intriguing that, it is a very slightly thinner oil, lesser shown additive package with lower, just about everything (moly/ZDDP etc) compared to the Petronas, seems to be on cheaper Group 3 base oils, with an Eco labeling seemingly for Asian or Emerging markets: https://www.valvolineglobal.com/en-th/synpower-eco-0w-20/ (in future samples please correct the Oil Type and Grade info) the website is pointed to Thailand, and the oil is made in Singapore. Our distributor in Malaysia does import it, but not widely marketed yet. Said Malaysian distributor website is still on the old "non eco" SynPower https://greatoceanauto.com.my/product/valvo...npower-sn-plus/ no actual API donut/cert and EOLCS also shows the same: https://engineoil.api.org/Directory/EolcsRe...ame%3DValvoline
I will create a new oil type in our system specific to SynPower Eco 0W/20. The "should-be" values for the oil's physical properties will be the same as what we have for the"non-eco" SynPower 0W/20. If you think they should be different, let me know, and I will look into changing them. The link to the Eco product you shared clearly shows the API donut sticker and API SP on the front of the bottle. The API license you linked to has the effective date 01 April, 2024; maybe this particular brand was brought to market after that date, and that is why it is not listed on the license. Regardless, the results suggest this oil has performed very well in your engine.

3) In relation to question 1 and 2, why does Valvoline perform better?
I do not know why you have less steel wear with this Valvoline oil than you were getting with Petronas.

4) How is my thought process that this current Valvoline being lower on Moly, adding Liqui Moly MoS2 additive should generally be only positives with no downside besides the additional cost?
It would be hard to get better results than these, so I would not expect any positive changes from adding Liqui Moly MoS2 additive. It should not hurt to add it if you want to, though.

5) Does MoS2 contribute to LSPI?
I have not seen any research linking MoS2 additive to LSPI.

follow up corresponding email

I have learned some things about MoS2 and LSPI... but not enough to draw a conclusion. This doctoral thesis is the most comprehensive study on LSPI that I have seen that is available for free. The section that is relevant to oil formation is on page 26, which cites several other research articles that have been done on the topic with very interesting findings, including some conflicting information about the impact of Molybdenum additives. I do not usually send links to scholarly articles to our customers, but I have a feeling you will appreciate it! If not, that is okay too

I'm going to run out of first page posts soon available for [img] tagging.

how do i work around the [img] tag limitation?
just posting img link without tagging it as image?

If you do not warm up/drive it long enough to at least reach 90c temps, you're better off leaving it cold storage never start up.

Otherwise, You'll do more harm than good through fuel dilution.

No good

Most cars needs between 20-30 minutes of idling even in Malaysian weather to get to 90c

If you drive right away normally, you can cut that time down by at least 5 to 10 minutes+ so at least still need between 10-25 of driving to get 90c (operating temp, and hot enough to prevent fuel dilution)

just go with fully synthetic, reputable brands, can be gotten for cheap.
and for your application, can definitely be more value than mineral/semi

oil change between 6 months to 1 year is fine.

Back with our Honda Integra this time using Motul 300v
the additive package is quite interesting in this 300V, especially the Moly, more than doubled even my purposeful additional additive usage

My own GT86 with Valvoline SynPower Eco 0w20 and now with Tan Chong MoS2 additives,
strangely... it seemed that visually black MoS2 only amounted to just...less than 200 moly PPM...?
https://www.quazacolt.com/uoa/gt86/20241014...Eco_mos2_01.jpg

no Q&A yet as it's been a bit slow for the folks at Blackstone labs. maybe through winter cold and going through changes with their new president

I've topped up twice within my oil interval to finish up 6 liters

No idea on my friend 2T usage, I don't drive his car enough to be able to properly assess.

I'm only using RON95, to my knowledge he too

Q&A
I'm interested to find out more about Molybdenum / MoS2 - how can we tell if the additive is on basic moly or the latest tri-nuclear moly?

I'm curious about my friend's Integra oil sample as his 300V has more Moly compared to my Moly additive, i still have 300less ppm compared to his moly that's originally in the 300v engine oil itself.


I've also noticed the increased in viscosity and flash point.
Considering my application that the car will see higher RPM/load/stress:
1) would the thicker oil offer better protection?
2) is the changes caused by the MoS2 additive treatment? (Such as the additive carrier oil)
3) would this MoS2 additive usage be considered positive , negligible, or even negative?

finally. lol.

not to mention various typos and errors compared to information provided from my oil slips. (all 3 reports also contained typos and errors)

This post has been edited by Quazacolt: Jul 7 2025, 12:15 PM

Molybdenum is very popular these days because it's one those additives that doesn't have any obvious detrimental issues.

The only problem is that they aren't like zinc or phosphorus that's able to cling to metal surfaces. Hence their benefits are also very limited.

Another "issue" is how there's differences in MoS2 similarly to base oil
https://bobistheoilguy.com/forums/threads/w...ar-moly.314523/
I'm not sure if there's any tests or analysis that can determine or differentiate the various MoS2 types.
(Base oil you can)

The insolubles are negligible and it's apart of my previous Q&A and recent Q&A/notes
Regardless, you can also refer to
https://www.blackstone-labs.com/all-about-insolubles/
Basically, the MoS2 are smaller microns than the test, as well as oil filter. (Otherwise they are all caught by the filter and just clog it up)

I've got enough data of TBN so didn't pay extra for it
But through experience and also my previous report, no it doesn't affect TBN

I don't have any way to tell as sulphur is not tested for all my samples from Blackstone labs.

I would like to think Sulphur is added minimally considering the potential issue on oil becoming acidic (faster), and/or cat con poisoning.

And of course, the EU low SAPS agenda.
But I could be wrong since the MoS2 engine oil additive I've been using (also 2 sample reports done, 3rd Sample with Penrite and Sepang track day is coming very soon!) is by Tan Chong, and may very well ignore any EU regulations, despite it's been OEM/produced by Liqui Moly Germany.

Yes the additive is indeed in very dark grey/black colour. Visibly very powdery.


No idea with Bardhal. Never looked into that brand.

Finally Q&A from my end

Engine
1) Can we consider the up trend of aluminium and iron be related to the Moly additives? or just a negligible difference that's probably just from the slight increase of mileage ran?
I think this is more just a negligible difference based on changes in mileage/use.

2) What does Trace (TR) mean in the report? Specifically, what % of fuel is present as opposed to a number value of previous samples such as <0.5? Or is it a binary value "yes or no" that is either trace or below 0.5?
It means "trace" — not enough to quantify. So, yes, there's fuel present, but the way we measure fuel, we can't get precise enough to say how much.

3) Would throttle body cleaners contribute to fuel trace?
I'm not entirely sure. Depends on when you used them and how much you used, I would guess... but this isn't something that, to my knowledge, we've isolated as a variable and tested.

4) From what I've mentioned in the notes, would the increased Silicon be a result of the vacuum leak?
It could be, sure.


Manual Transmission
1) What does Boron and Magnesium do for transmission additives?
I'm not entirely sure. In engine oils they serve as anti-wear/anti-corrosion additives and detergent/dispersant additives, but I don't know that we know for sure what purpose they serve in transmission fluid. Might be the same purpose.

2) Considering the additives are quite identical, the only difference between Mobil and Motul is just the base oil?
I don't know that I'd call them identical, but very, very similar. There could be other things that are different between them — things we don't test. Like, for example, the base stock of the oil.

3) Does Blackstone Labs have any tests that can identify any samples's base oil?
Not at this time.


Rear Differential / LSD
1) As this is my first rear differential sample, and the car was manufactured in 2013, with a significant amount of mileage, it seems like the differential is still kinda running in from the wear trend? (nickel / silicon amount)
I'm not sure — I guess it depends on how many oil changes have been done. If it's been more than a couple oil changes, I wouldn't expect this metal to still be from wear-in.

2) My friend's previous report highlighted a lot more Nickel as I was slightly worried, and referred to his report [omit]
His unit was considerably newer; probably that was a break-in sample.

3) It does beg the question: Why do the universal averages differ quite a bit from both our differential sample reports? It's as if the universal average does not contain nickel at all while ours have a lot more.
Because our differential average files aren't as precise as what the engine average files are. Most people have no idea of the make/model of their differential, so anything that comes with a Toyota name is put together in the average file — Anything from Tundras and other pickup trucks to sportier cars. It would be ideal if we separated the units out a bit more and had precise averages, but we don't see as many differential samples as we do engine oil samples, so the number of samples (and the lack of information about the samples) prevents more specific averages from being created.

4) My friend's (assuming) factory fill seemed a lot thinner. How much does viscosity contribute in reducing wear?
I don't know that it does, necessarily. For differentials, this isn't something we've explored a lot. We've explored it a bit more in engine oil samples just because we get so many more engine oil samples than differential samples, so there's enough data to come up with some meaningful reults. Also, the frequency of sampling engine oil vs differential samples lends itself to a bit more comprehensive examination. It's hard with differentials when they're only sampled every 30,000 miles — and sometimes they're only sampled once or twice within a vehicle's life. It's hard to get any hard-and-fast data on how viscosity affects wear patterns.

5) Considering probably the only downside for thicker viscosity oils in a Torsen differential is only fuel consumption or efficiency, if reducing wear is the goal, just go as thick as possible?
I don't know; we don't have enough data to say. (see previous question)

yeah i find it weird myself too as i never noticed that eco labeling Valvoline in Malaysia.
closest thing i found is Valvoline Thailand lol

i got it directly through a friend, through direct distributor or uh partnership?
