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 .

How is this oil doing?

LOL. Didn't know anyone is still using Honda oil like me.
I'm on 110k km now

I think the Honda oil is adequate enough for normal day to day drive. No need oil that are too extreme

This oil is still doing fine and appears to be quite clear of grey dark contaminants, indicating good mechanical condition.
However, there is appearance of a centre zone perimeter ring that correlates with dispersancy capability of this used oil and that's something to keep watch, IMHO.
Having said this, I think this used oil is good to go on.

Cempedak has similar HGEO 0W30 in use and seems to have similar trends in emergence of perimeter ring at rather low oil mileage.

Maybe you should take another blotter spot 2000 - 3000 km down the road and see how the perimeter ring develops ?

Btw, what's the car/engine model in use ?

Ok.. I will update you guys after another 3000KM. The car is Honda City 2010 model with L15A7. I take good care of the engine and seldom rev it above 3,000 RPM. Drive like an uncle in order not to stress out the engine and gearbox. Oil change are usually set at around 7 - 9k mileage.

All the EO masta here ...

I saw there are plenty of Shell Helix Ultra for sale in Giant for 85 each.

They are made in Europe but all the wording seems to indicate its for Russian market. What do you guys think of it ? Authentic ?
