Thanks bro Zeng. I will wait for at least 48 or 72 hours to repost my engine oil test. Btw i think that i read somewhere you are from Pandamaran ka? Pah Sang people?

Your pleasure .

Hmm .... my go to workshop is in Jalan Pendamar , Pandamaran for his trustworthiness and quality workmanship .

I'm from USJ/Subang Jaya .

Hello bro zeng. I have waited the blotter test (72 hours) 3 days plus for your review. with approx 6500km travelled with the oil. Appreciate your advice on the blotter drop i did.

About the oil dilution, i check my dipstick level still same as i change my oil. No sign of oil level increase. However, Can this Petronas Syntium 3000 5w-30 oil last until 10,000km? I m thinking to stick one brand for long term though.

Hi Bro ,

These 72 hour blotter spot test pictures should have been 'matured' by now , and it clearly demonstrates they are free of (or lack of) structures or zones like centre zone ; aureole zone /perimeter ring and diffusion zone which are good news as it indicates the superb condition of this Syntium 3000 5W30 used oil at 6,500 km .

Generally, the diffusion zone is very transparent and light yellowish in colour indicating very low levels of combustion by-products or contaminants .

The jagged edge is not darkened , indicating a very mild or negligible level of water moistures which is of no concern .

Yes, this blotter indicates 'severe' level of fuel dilution by looking at the very visible translucent annulus of 80 mm and 65 mm diameters on my screen (of Right Hand Side of Top picture measuring in North/South alignment) .

This 'severe' level of fuel dilution is somehow not reflected in your so-called engine oil level increase .

IMHO, this 6,500 km used oil is fit for continuing service and IME 10,000 km is a non-issue and poses no problem whatsoever .

Is the oil changed ?

Edit: IIRC, Mazda3 OEM recommended oil change intervals is 10,000 miles (16,000 km) in U.S. for a 2013/14 .

Hi bro. Thanks alot for your reply and comment very much. Now i am confident that this Syntium 3000 is good to go until 10k km. This oil is not change before and infact this is my first time to use this syntium 3000 in which previously i tried mobil 1 ep and shell helix ultra 5w30 (ACEA A5/B5). As for the syntium I suppose it is a ACEA A3/B3 oil? Since its never stated (only SN plus/GF-5)

hi zeng, just wondering if im interested to share my oil here, I just need to drop a few on paper right? doesn't need any specific sheet is it?
I'm using duron now on both my scooter and car.

The local Syntium 3000 5W30 SN plus/GF5 (with or without SE) in question does not have/meet ACEA A5/B5 specifications .

However, European sourced Syntium 3000 FR (Ford & Renault) 3000 SN (plus) /GF5 , which are available here on online stores , carries much demanding and tougher Renault and Ford OEM approvals like Ford WSS-M2C913-C, 913-D & Renault RN0700 , whose specs is ...........
over and above than that of ACEA A5B5 specs , which in turn is over and above API SN(plus) /GF5 specifications .

As regards your expressed confidence in 10,000 km usage for this SN plus/GF5 , I consider it as well placed and appropriate .

For comparison purpose , you may wish to refer to this @90Boyz Syntium 3000 FR SN/GF5 blotter of 11,680 km in a Kia engine in post #1 .

Add :FR spec sheet ......

Yes, any non-glossy paper such as A4 size letter head or printing paper would do .

Some people here uses coffee filter paper that seems to 'differentiate' the blotter contrast better , IMO .

As suggested, sample is best taken after more than 20 minutes - an hour or more of driving and ..........

within 20 minutes of engine shut down while engine oil is hot/warm and not cold .

This technique may be used on gear oils etc , other than engine oils or saloon cars .

thanks bro will find the coffee paper and a syringe, so I could drop without messing the paper haha.

if i check this thread earlier i might be sharing more cos i regularly change different type of oil previously . sighhh banyak rugi haha

For interim and periodic checks , you may drop the blotter spot from the dipstick whilst checking/ascertaining correct oil levels .

Btw, I wish you would benefit from reading post #1 in this thread .

Hi Zeng, would you able to share your thoughts on this 5w30FR blotter that just done about 5,218km in a 130k mileage turbo engine?

The left top blotter was done after warming up for 10 mins while the bottom blotter done about 20 mins driving.

Both are about 48 hours by now.

Mind sharing what is the engine model here ?

It seems to place quite a demand on its engine oil , IMO .

Edit: If I may speculate , this engine may not give you good fuel economy in relation to a Japanese Port injection engine .

This post has been edited by zeng: Nov 2 2020, 11:01 PM

It's actually a Proton CFE engine running higher boost.
Fuel economy is average I would say, about 10L/100km, if driven lightly about 8/9L/100km.

Is the oil nearing the end of life?
I actually planned to change out the oil to try out on the Aisin 5w30 PAO, perhaps would able to share the blotter for you to analyze so that we could learn more about it?

The centre zone of this 5218 km Syntium FR 5W30 is not light yellowish but slightly grayish indicating presence of some levels of larger size and/or heavier density contaminants/metal wear particles .

It is not yet darkened black or opaque , which we would like to avoid .

However , this low mileage blotter seems to suggest emergence of slightly darkened aureole zone / perimeter ring , indicating agglomeration of contaminant dirts though detergency and dispersancy performance is something to monitor and watch out for .

Diffusion zone is yellowish and good with low levels of lighter density dirt .

Water moisture is negligible if any, and fuel dilution seems to be absent .

Overall this 5218 km used oil is fit for continuing service in this Campro CFE , IMO .




Ok, this higher turbo boost may explain the emergence of centre zone and aureole zone in this lowish 5218 km blotter , I don't really know .

Of course higher boost may relate to slightly 'lower' fuel economy .



No, the used oil is fit for continuing service IMO , never mind the higher turbo boost which may whack the engine oil in your driving .

You may want to consider taking a blotter spot test after another 2000-3000 km from now for monitoring purpose if you have not yet decided to get the oil replaced .



I am quite impressed with a Aisin PAO 5W40 (not 30) blotter performance in a Kia engine in post #1 .

You may also have a look at a non-PAO Aisin 5W30 blotter here .

Thanks alot for sharing. Appreciate that 👍🏻 Any possibility that the slighty darkened aureole zone caused by leftover of flush cleaner that I used before oil change?

Oh yes, leftover of flush cleaner surely is a major factor contributing to the emergence of darkened aureole zone/perimeter ring in this lowish 5218 km blotter spot .

Seafoam products by @ cempedaklife in post #1 also corelates the phenomenon .

Btw, what is the name brand of flush cleaner in use ?

This post has been edited by zeng: Nov 3 2020, 09:10 PM

Thanks for the highlight, definitely an interesting find. I think the brand is DPS engine flush, somewhat cheap engine flush purchase along from EC Auto shopee.

It was quite shocking to find the aureole zone to be honest as I usually change my engine oil around 5 to 7k for fully and estimated every 2 to 3 months to reach that mileage.

Would like to know this Aisin 5w30 PAO stated in the bottle that it is using VHVI base oil, does that mean it's a Group 3+ with added PAO and Esters and not group 4 or group 5 engine oil?

Replacing fully synthetic after 5 or 7K km oil life every 2 to 3 months in a Proton Campro should not have come across the emerging darkening aureole zone in a 5K 'ish km oil blotter as is in your case , IME .

I'm of the opinion that this DPS engine flush contributes mainly (if not wholly) Edit: 'responsible' , for the emerging darkening aureole zone in this 5K'ish km blotter spot , with or without higher boost turbo , with hindsight .

Question now is , does this relatively 'dirty' 5K'ish used oil life being shortened ?

I would think so , according to media articles .

Does this used oil not fit for 10,000 km usage , and be condemned soon ?

I don't think so when one evaluates with high ringgit and quantitative Used Oil Analysis or an foc qualitative blotter spot test IMHO .

VHVI base oil is a grade or two lower than a Group 3+ aka (Shell) GTL base oil .

I would classify it as Group 3 or Group 2+ mineral base oil .

Btw , PAO is Group 4 and Ester is Group 5 .

Hence, this base oil combination of Aisin 5W30 PAO should be good for high temperature application .

However, it does not have a certain Euro OEM approvals though it claims to meet or exceed the specs IMO .



Its PDS claims 'Low SaPS' though , which is a good feature .

Hi Speedy ,

This Aisin PAO+Ester 5W40 SN claims to be a Low SaPS oil , which may partly explain its superb blotter spot test performance here at 12,000 km oci IMHO .

Dear sir,
I have a doubt , does this Aisin fully synthetic comprise of 100% PAO+Ester ?
As far as I've known, most fully synthetic usually contain some 5%-20% PAO (based on MSDS , though not 100% accurate due to trade secret perhaps). If 100% PAO isn't it very expensive to produce
