Hi,

New development as stated above.

The current generation of Shell HX8 X 5W30 with a newly acquired OEM MB 229.5 approval status would beat the hell out of the relatively 'lowly' Petronas Syntium 3000 5W30, in terms of performance specifications.

I believe the current HX8X in market circulation are the still old stock without the MB229.5 approval. Probably have to wait until next year before we start seeing the newly enhanced HX8X.

On July 2020 after 18 months and 27k kms later at Odo 306,197 km another ATF drain and fill was carried out whereby one bottle 473 mL of K&W High Mileage Trans-X 75K Automatic Transmission Treatment was added, for the fun of it rather than related to any transmission shift problem then.

The transmission shift has smoothened and improved especially during everyday cold morning first shift.

Attached below is a 13 month 'dirtier' looking ATF Blotter Spot Test K&W mixture after 18,896 km at Odo 325,093 km and going......

Hi bro Zeng, pls help to review .
Suzuki swift 2007 1.5l, using Petronas 5w30 Syntium 3000 FR Fully Synthetic

Last changed EO on 3-July-2020
Current mileage clocked at 98k
EO only run for 3K

1st photo: 24 hours
2nd photo: 48 hours

This car is only used for short distance travelling.
EO still can continue to use?

Hi Bro,

Short trips is said to be 'bad' for engines apparently due to tendency or promotion of corrosion wear related to cold engine oil operation.

This corrosion wear is being 'reflected' in your low'ish 3000 km blotter spot of a rather high specs (with Ford and Renault OEM approvals) Syntium 3000 FR 5W30 here.

There is absence of grayed or darkened Centre Zone, which is good news.

However there appears to be emergent darkening of Aureole Zone/ Perimeter Ring, which imho remains harmless for now.

You may want to monitor and watch closely the potential further darkening of this Aureole Zone/ perimeter ring with continuing usage of this 3000 km FR oil.

The Diffusion Zone is light and clear indicating very low levels of combustion dirts/contaminant , another good news meaning it still has a rather large capacity to further adsorb further release of combustion by-products/contaminants with continuing usage of this used oil.

No signs of water moisture or glycol coolant contamination in this blotter, again a good news.

Thers appears to be very slight fuel dilution issue with very light coloured and translucent halo at the outermost zone which I believe remains harmless, despite the short trip driving patterns .

Overall, I would rate this 3000 km FR oil as fit for continuing service with very close monitoring of its trending of darkened Aureole Zone if it ever surface in due course.

that is good news. currently, I am using Syntium 3000 5w30 which is already due for change since July. I thinking about whether to continue the same oil or
switch to Shell HX8 X? For my past experience of Shell oil like HX7 5w30, the oil is on the heavier side and throttle not so responsive vs other oils I tried like Mobil, Petronas. Just checking how does this HX8 fare?

Hi Zeng,

Do you have any info on the minimum oil specification to meet the requirement for MB229.5?

I can't find any info on the MB 229.5 minimum requirement.

Yes, it used to be very very difficult to find.
Give me sometime please, I will come back to you.

TQ Zeng.

Hi bro,

Generally no 'structures' in this Penrite ATF FS Multi-Vehicle 21k kms blotter spot which translates as good news.

My 19k kms blotter with Trans-X ATF oil treatment in Type IV looks 'dirtier' .......
probably due to some dirt being dislodged from the ATF fluid system?

I'd phobia in extending oil change interval of regular mineral ATF (like Type IV, Dexron III etc) beyond 20 or 30k km ....
even though US guys are doing it at up to 100,000 km, with a fully synthetic ATF though.

This Penrite FS Multi Vehicle has a solid parameters/specs and should do well in applications calling for Dexron III or Toyota Type IV, imho.



Edit: Bro, mind sharing the odometer reading ?

Odo on blotter time were 145,570km
oil age about 1year 3moths old
btw i will redo the blotter as i felt that the engine wasnt warm enough for the test.
sunday morning will posting another 48hrs test .

Hi bro zeng, with regards to the new updated specs of HX8 i tried to find about the oil whether is it mid saps or high saps. Seems like no info on this. While Petronas Syntium does stated clearly is mid saps. In between both which is more suitable for Direct injection? Typical driving is city drive and occasionally highway drive only.

Hi Bro,
This 21k kms Penrite ATF FS blotter shows total absence of centre zone, aureole zone etc , which implies good news or as new condition.

It is clean and transparent indicating nearly absence of contaminants in wear and/or absence of oil oxidation phenomenon etc.

This FS ATF should last longer than factory oils, I suppose.

Btw, what ATF oil does Honda recommends for this model , and what's the factory recommended change intervals if you don't mind sharing?

Hi bro Zeng,

Honda always recommend using their Honda genuine DW1 ATF oil which manufacture by Idemitsu Lubricants for Honda Auto transmission


As taken from Honda Website were the oil change interval for ATF.

Wow, 60k km oil change interval for DW1 according to Factory.

I'm not sure whether DW1 is always a fully synthetic from factory, other than Honda approval (which Honda isn't issueing, I guess) and appropriate DW1 additives, this Penrite fully synthetic ATF base oil should equal if not better than factory DW1.

What's your typical oci for DW1 as practised?

May be time to read out more on DW1.

Shell HX8 w/wo X MB229.5 is a high SaPS oil.

European OEMs like VW/Audi do recommend a high SaPS VW 50200 oil for their Direct Injection engines. However, I am not certain whether the same applies to MB.

May be someone knowledgeable on this can help throw some light on MB practice.

I wouldn't be surprised if MB recommends high SaPS oil in their Direct Injection engines, just my speculation.

On Direct Injection engines and SaPS content I do buy the idea that a Mid or Low SaPS oil is preferred to a high SaPS in a DI, though VW/Audi seems to deviate from this at times.....

In your general context, if the fully synthetic oci is say 14,000 kms and less I would likely pick a Petronas C3 to directly benefit (hopefully) from its 'friendlier' relations with DI engines.

If one is adopting say, 16000 kms or more oci I would likely pick any MB 229.5 high SaPS over a Petronas C3 for its assured performance in extended change interval.

So, at the end of the day... there is no right or wrong oil really especially if (typical Asian) car OEM specifies SN/SM only.

Thrust, I still owe you the MB 229.5 thing yeah..

Edit: Approved Mid/Low SaPS oils for MB engines are MB229.51, 229.52 and 226.51 approved.

Previously was having issue with the AT pressure switch back in May 2020 that time mileage for the oil just only 18k KM, then foreman recommend me change the pressure switch as well replace the old oil and ATF Filter.

Here's continuation of total 10w-40 semi syn oil at about 9.5k km. 48hr blotter.
180k km proton inspira.

Will arrange to change oil in 2 weeks time.
