🤔 your statement kinda got me curious too bro zeng, maybe I should try to extend it's usage & see how it develops over time, blotter test every 1k km

No need to debate on Euro 2 or Euro 5 diesel anymore. All diesel at all pumps are now Euro 5 already. Now difference is whether there is 7% of palm oil, 10% of palm oil or even 20% of palm oil in the near future.

All the 5 oils above are properly certified/claimed Heavy Duty Engine Oil HDEO diesel (CI4,CJ4, CK4, ACEA E7 ,E9 ) with various truck OEMs' approvals whose detergency/dispersancy properties requirements are very much higher that of a properly certified/claimed ACEA A3B4 PCMO meant for Light Duty Truck.
May I know what is the Euro spec of current 'normal' diesel fuel here other than the Euro 5 diesel on offer?
Euro 4 of 50 ppm sulphur ??

I used to hear horror stories of later model diesel truck engines having very pricy fuel injectors being damaged by Euro 2 (?) diesel fuels then.

Not sure if current diesel engines and its injectors are totally fine with current 'normal' Euro 3-4 diesel fuel.

Is it a waste of money for current later model trucks using Euro 5 diesel, which is supposed to be friendly providing good cleaning to fuel injectors ? Or it makes no difference, in practice ?
At 5000 km oil change interval, any of the above mentioned mineral HDEO 15W40s would be good for 10,000-15,000 km usage no sweat. If I were you, I would ignore any semi-syn or full-syn HDEO for any oil change interval below that of 10,000 km.
Speaking of Fuel Economy, I think you should seriously consider this Caltex Delo 400 MGX 15W-40 API CJ-4 (Mineral) whose UOA from @e-lite above displays tonnes of friction-reducing additives like Moly and Boron.
Not sure whether the other semi-syn or full-syn HDEOs would contain Moly and Boron too.
At 5000-10000 km oil change interval, I would give them a miss as it is not value for money.
I would agree with your position and Bitog's (where I used similar username) that your Hilux Revo diesel engine is good with the ACEA B spec'ed PCMO oils.

Your continuous usage of the current Helix Protect 0W30 A3B4 at much higher mileage of say, 8000-12000 km would be interesting suggesting a B oil is fine.....

However, at this preliminary stage of full-syn Helix Protect blotter, I'm unimpressed really with its blotter 'performance' thus far vis-a-vis that of a properly spec'ed HDEO CI4,CJ4 (E7,E9) mineral oils.
The used oil at 4810 km looks good on the dipstick.

Question: Are the diesel soot particles and combustion contaminants having agglomerated into larger/heavier size lumps , and getting stucked/sticked onto internal engine components and its surfaces while NOT being adequately cleaned off by detergents with a view of aggressively dispersing the suspended soot/contaminants around the body of lubricants?
Hence, the dipstick used oils looks 'clean'?

Thanks bro zeng for detailed suggestions. I'm kinda on the fence right now, whether to use back HDEO at 5k km or continue to extend current oil & observe it's performance. I've done some research on other 4wd model oil recomendations, ACEA B3&B4 or C3 for Mitubishi Triton, Ford Ranger, & Chevrolet Colorado, API CI-4 for previous Isuzu D-Max, no idea on the new 1.9 model.

In your honest opinion bro zeng, should I continue with ACEA B class engine oil, or should I use diesel specific HDEO, better spec-ed ones like Shell Rimula R6 LM 10W-40 full synthetic API CK-4 or Shell Rimula R5 LE 10W-40 semi synthetic API CJ-4, for extended interval, in which only available in 20L pail here.
The only diesel specific 30 weight oil available here is this one

Total Quartz Diesel 9000 5W-30 full synthetic API CI-4

From my observation, at 5000km, these oil tend to show soot "particles", by particles I mean something like a full-stop sized particles, too bad I don't have pictures to show..

Like I said, your oil actually looks very clean but the oil is not doing its job in terms of detergent and dispersants. My diesel oil is black in color even though it's 1000km used only. If I got time, then I will take some pictures for you.

It is worrying that you can see soot particles in your oil sump which means your oil filter is not doing its job too.

Someone's UOA for Delo sports synthetic blend 10w-30 (credit to Winko Industrial):

I'm inclined to agree with your suggestion that the Helix Protect 0W30 A3B4 may not be doing its job in terms of detergency and dispersancy properties.

'Seeing particles' in the HDEO CI4 by Gin87 may mean the 'dirty' mechanical conditions of the 2019 Hilux Revo diesel engine, however I would like to assume this 2 year old Hilux engine is not 'dirty' per se but in very clean condition , what more its previous oil change intervals of 5000 km is too short and 'premature' imho.

Hence, I would speculate 'particles' as seen or felt by Gin87 inside the CI4 HDEO used oil sample is a strong indication of the excellent and top form detergency and dispersancy properties of HDEO CI4 vis-a-vis this Hilux Protect 0W30 A3B4.

Thank you for sharing a 10,000 km UOA of a HDEO in Chevron Delo Sports 10W30 in a Ford Ranger 2.2L diesel.
This UOA performance is fantastic but, its top up volume of 7.6L may have distorted the complete picture, no?

Btw, I wish you don't mind me sharing this Delo 10W30 CI4 UOA in Post #1 of this thread?

The picture doesn't belong to me though. You can use at your own discretion.

Most diesel pickup trucks have about 7-8L oil change capacity. The 7.6L figure should be oil change capacity.

I forgot to mention that I've used Liqui Moly Pro-Line engine flush prior to this oil change, not sure if it affects the dispersancy of current oil...

A typical engine flush like the said Liqui Moly Pro-Line Engine Flush prior to an oil change would have helped cleaning out or dislodging carbon dirt contaminants previously stucked on the engine component surface, hence this is supposed to 'lessen' the workload of the detergency part (not dispersancy part) of the new replacement oil in this Helix Protect.

With 'increased' amount of loosened carbon dirt particles within the new replacement oil, the new Helix Protect should have been able to dispersed the carbon dirt contaminant, which I think it did.

However it seems to me from the 4810 km blotter spot test performance of this Helix Protect, whereby the centre zone AND aureole zone/perimeter ring are generally darkened but the diffusion zone remains very light and transparent leading me to speculate that the Dispersancy part of this Helix Protect may be struggling very hard to dispersed off or spread out the 'added' load of carbon contaminants further 'outwards' towards external zones like Diffusion zone.

No need to debate on Euro 2 or Euro 5 diesel anymore. All diesel at all pumps are now Euro 5 already. Now difference is whether there is 7% of palm oil, 10% of palm oil or even 20% of palm oil in the near future.

After searching around, I've found these 2 oil in my local workshop that sells 'high end' brands like Motul, Morris, & Liqui Moly. Penrite HPR Diesel 5 5W-40 & HPR Diesel 10 10W-40, both semi synthetic & satifies both ACEA A3/B4 & API CI-4. A little bit thicker in viscosity but I think it's a good candidate for next oil change.

Hi bro,

Thanks for uploading your blotter spot test images.

There is a shade of gray/dark-gray in the centre zone, indicating presence of some heavy particles not being dispersed outwards away from centre zone.

Looks like aureole zone/darkened perimeter ring is about to emerge and being formed, indicating commencement of agglomeration of quite big/heavy particles. Is the detergency/dispersancy properties of this Shell Helix Protect fully synthetic 0W30 struggling with 4810 km usage , albeit with some off-road application?? IDK.

The diffusion zone is clear and not grayish, which is a good news IF there isn't much dirt particles to disperse to begin with.

However do note Diesel engines are typically prone to soot production, question being may be this 2019 Hilux Revo Diesel engine is so good that it releases very little soot in relative terms vs others?  IDK.

There is absence of jagged darkened edge surrounding the diffusion zone, indicating absence of water moisture (at 4810 km usage and 8  hour drive probably).

No signs of translucent halo at the outermost zone indicating absence of  diesel fuel dilution phenomenon.

Overall, I believe this 4810 km Helix Protect 0W30 is fit for continuing service.

My concern for now is to monitor very very closely the conditions of centre zone AND aureole zone/perimeter ring as well as diffusion zone.

Edit: Is this Shell Helix Protect fully synthetic 0W30 SN+ A3B4(?) really a diesel engine oil??

Hi Zeng, im not sure if i do this right but here you go

Campro IAFM 6 years old age. Mileage now at 134k km.

Sample taken after 40 minutes engine running, after 5 months after the last service at 130k km

Petronas Syntium 3000 5W30 Fully Synthetic. If possible want to drag the next servoce to 9 months. Thanks in advance bro.

Btw, you have here a rather high quality/spec engine oil in this local Petronas Syntium 3000 5W30 SN+.
It is a mid-SaPS engine oil of 0.8% weight Sulphated Ash (Hence I expect its superb performance, never mind the fact this Syntium is not ACEA spec'ed).
Don't worry about its seemingly low'ish TBN of 8.0 , my dear friend.

Between the Shell HX8 X 5W-30 vs the Petronas Syntium 3000 5W-30, which one is actually better?

I have bought these 2 engine oil before.. The Shell was used in a Myvi. Noted it's clear colour engine oil which looks really clean and pure.

Syntium on the other hand was used in a Honda. Looks like your regular gold dyed engine oil,

How much is the retail price of HX8 X 5W30 at petrol station?

My Syntium 3000 i bought at Petronas for RM180.
Really need someone to convince me if i can drag the service interval to 9 or 12 months. Nowadays, because of mco i dont drive that often and dont want to go to workshop too often. I dont mind paying a RM180+/- oil as long as the oil is good and can stretch as long as possible. But i do drive the car once a week (over 80kmph) for about 20 minutes.
