24hr blot

Shell Helix Ultra Full Synthetic 5w30 (Made in Hong Kong)
Elantra 2002 1.8
Oil mileage 10,006 km

Still using Honda fully syn 0w30 engine oil.
This pic taken 60 hours after sample taken.

Last oil change did with throttle cleaning in workshop

Ooops .......... thousand apologies ...
Ok, will respond in due course.

Btw, on API certifications/licensings of engine oils or the lack of it....

Hmm cempedaklife ...... the centre zone perimeter ring appears very obvious, doesn't look good for its detergency/dispersancy.
I thought Honda 0W30 could do much better than that.
It could be due to cold temperature when doing sampling.
Next tests try do it hot, after say 20 minutes of 20 km run.
Check with previous posts from this thread, there was one Aisin oil type very impressive blotter spot test. Try use that particular one if you are going for Aisin.

cant remember if i take this cold or hot.
was thinking to switch, but till now unsure, if to go for aisin or shell. next change should be around jan.

Just before pouring this oil, you did throttle cleaning ?



Edit: Your June 8 post saying sample was taken after 15 min from pasar, not this sample ?

I did the cleaning same day at the workshop and change engine oil. Can't remember what they did first. I yhink change oil first only clean.

June 8 is another sample.

For high mileage engine, should be preferable to go thicker, more so when there is minor oil leaks.
Besides, 5W40 is most likely fully synthetic oils, where as a 5W30 could be just mineral oil, or semi syn, although there is also fully synthetic depending which particular oil type.

Aahh ....may be the remnants of dirty stuff after the throttle cleaning has gone into this oil sample.IDK.
If this is the case, may be we can't 'blame' the Honda 0W30.
Btw, if you are still using this oil sample (meaning haven't change this oil sample yet ), may be can take another blotter spot test after another 2000 -4000 km and see how the oil performs ?

This Aisin fully synthetic (PAO+Ester) 5w-40 API SN used by speedy is powerful, you may give it a try.
On Shell Helix Ultra 5W40, I'll upload a blotter spot say next 1 to 2 weeks after hitting 14,000 km and see how it goes ?

Good blotter spot test at 10060 km, no sign of centre zone perimeter ring indicating good detergency/dispersancy properties close to as new.
No dark grey dirt/contaminants in centre and intermediate zones, indicating contaminant levels not very high at this high mileage.
No indication of fuels in outermost perimeter zone.
Engine appears to be in tip top conditions and well maintained.
This oil is still serviceable and could probably go for another 2000 - 4000 km and test.
Did you go on ?

Edit: Apologies for late response, alphaz.
Edit2: I personally consider this 10060 km SHU 5W30 blotter spot as performing relatively better than Honda 0W30 at 3750 km above.
Not trying to bash Honda 0W30 though.

Thank you zeng for your comments. I'm almost 14,000km on this EO now, I will do another test soon. This EO seems to be very good, it's a bit expensive at RM160 per 4L though. That's almost twice the price of SHU 5W40 one.

Double post.

Comparing my Shell 10099 km blotter spot, Helix Ultra 5W40
against your 10060 km blotter spot ,Shell Helix Ultra 5W30 (Made in Hong Kong)
.... both appears to perform equally well, I believe.

I'm awaiting another SHU 5W40 14100 km blotter spot to 'mature' and will upload in the next few days from today.
This 'Made in Europe' Shell Helix Ultra 5W40 was bought from Giant at RM99.90

Thanks for posting Chemistry, sorry for the late response.
As is typical of HDEO, this 12558 km blotter spot tests doesn't demonstrate darkened centre zone perimeter ring, indicating high detergency/dispersancy capabilities of used sample.
Intermediate zone is a bit greying in colour, but it's still good.
It appears to me this semi synthetic SHP 15W40 can go beyond 12558 km OCI in this carburettor engine.

Many thanks for taking time to comment here.
The HDEO was drained at OCI 13000km and has been in service for 14 months . I think it has done its job very well.

I had used HDEO mineral CI4 15W40 for around 8500 km oil change and found them very robust.
Yours is semi synthetic with CK4 of 'higher' specs.

This Bardahl MXP 5W40 FS blotter spot has very vague centre zone perimeter ring, which is good news at 6829 km.
Detergency/dispersancy capabilities of oil is still strong and probably can still go on for several thousands km more.

Wow, nice blotter spot test at 17000 km, Senscents.
No signs of perimeter ring near the centre zone, I would assess the oil detergency/dispersancy properties are in top form and there is probably still life in this oil.
As you took sample at cold, the fuel dilution can be observed at the outermost perimeter zone.
Btw,I would strongly recommend this Platinum Velocity 5W40 to the readers on lowyat using typical Asian engines .
