To be fair, Aisin did not claim 100% pao+ester base oil. So one should not assume that as well. If you look at full ester based oil, price goes well above RM250. So what you pay is what you get.

Actually does 100% PAO engine oil exist in market?

Really tough. I only manage to come across 1.

https://www.lazada.com.my/products/kixx-pao...lBrUUM&search=1

On the bottle, it says Fully PAO la

i think no... but Penrite seems to claim 100% (or is it 100% full synthetic je? lol)
https://www.penriteoil.com.au/knowledge-cen...engine-oils/454

out of curiosity, looks like the claim is real

>80% are the chemical based base oil (no petroleum)
rest are esters/(not base oil, zinc based) and additives to make up the rest of the composition

What's the difference between 100% PAO and 100% ester?

PAO polyalphaolefin base oils have negative characteristics such as the tendency to shrink seals and trouble dissolving common oil additives , i.e additives solubility problems .

They are commonly blended or combined with organic ester and/or petroleum synthetic base oils to provide a blended base oil that does not have these negative characteristics.

There may be engine oils claiming or advertising as 100% PAO , but these oil formulations cannot be totally free of ester or petroleum synthetic oils IMHO .

Just my 2 sen .

Item 2 , a kind of ester ? IDK .

Item 3 , ZDDP anti-wear ;

Item 4 , Additive package (15 - 25% )

Mobil 1 New Life 0W40 (Tesco) MB229.5
Oil Life : 19,160 km
14 months oil life thus far .
ODO :312,990 km in
Car model: Toyota Avanza 1.3L
Engine: K3VE Multi Port Injection
Added some 100 mL of graphited engine oil in Elf Molygraphite 15W50 .
Make up oil added : Nil

48 hour blotters ,





Absence of darkened and opaque centre zone .

Absence of darkened aureole zone / perimeter ring indicating no agglomeration of contaminants , yet .

Diffusion zone darker than before , indicating increased levels of dirt/contaminants/combustion by-products but appears harmless for now .

Darkened jagged external edge indicates presence of moisture in used oil , which is supposed to aggravate corrosion wear .

But centre zone/aureole zone, perimeter ring and diffusion zone do not indicate alarming levels of wear/dirt/contaminants caused by moisture corrossion .

Fuel dilution seems to be absent from blotter sample .

and ....... going , for now .

The difference is :
100% PAO base oil formulation must have some ester or petroleum synthetic base for additive solubility .
100% ester base oil formulation may NOT have some PAO or petroleum synthetic base .

I am interested source and citations please?

Sorry , no citations or source but laced with ambiguity opposite that of certainty .

Persons who had done research rather extensively on 100% ester formulations may be able to throw some light on this .

Hi ,

If not for your disclosure of its 2330 km usage , this clean blotter would have been mistaken as that of an un-used virgin oil blotter from HGEO semi syn 5W30 SN .

There is complete absence of 'structures' in this 2330 km blotter , which means good news as it indicates 'near new' condition of the used oil sample with minimal or negligible amount of combustion by-products or contaminants/dirt .

The very light colour of the blotter also indicates very very minimal oxidation of oil .

You may scroll through Post # 1 of this thread for a 4.5 years usage at about 6.8K km blotter of similar Honda oil uploaded by @Trony for comparison , though of differrent engine models (?) and driving pattern .

Item 2 Long Chain Alkaryl Amine is NOT an ester . It performs as anti-oxidants .

Item 3 Zinc Alkyl Dithiophosphate /Phosphorodithioic Acid is an ester . It performs as anti-wear additives , but it is not ZDDP which is also another type of anti-wear additives .

Hi bro zeng,
Thanks for the explanations
This bottle of oil sit in the closet for quite some times , maybe 2years ?
also i also bought a Aisin 5w30 pao + ester on 11.11 promo
will drain out the Honda Oil when reaching 6k

So we have known that 1-decene is PAO (base oil).
Do you have any idea ester base oil appears as what chemical name?

Yes, any -decene displayed in typical msds is always a PAO .

Ester as the little I know of , is a general terminology comprising numerous varying combination of elements such as Zinc Alkyl Dithiophosphate etc above . Very unlike PAO chemistry .

It's sad that Motul 300V does not disclose much about ester component in their MSDS. Otherwise we would at least have some clue.

Hi Zeng, just sharing my 1800km blotter test with the same engine but with Aisin 5w30 pao+ester with ceratec.

Should I be worry about the silver lining around?

Mind sharing engine model and odometer km ?

Is the blotter hour matured , i.e 48/72 hours ?
