Follow up of my Shell Helix Ultra 5w30 at 14,000 km.

19 hour blot:



37 hour blot:



What do you think?

learnt something new today, blotter test is totally new for me, tq TS

I think its time to change your engine oil.. Looks brownish already. My guess is the brownish color particles are combustion soot.

EO: Pennzoil Platinum Velocity 5w-40
Car: Perodua 2014
Engine: 1.3 auto
Millage: App. 22000 km
Odometer: App.91,000
Driving Condition: 50% City; 50% Highway

Wow, obscenely good 22000 km blotter spot test ......
and still showing absence of centre zone perimeter ring, indicating the used oil detergency/dispersancy properties are on top of situations.
The centre zone is generally not greyish dark for its long 22000 km usage, indicating clean engine oil condition with not much of contaminants and combustion byproducts.
Slight indications of fuel at the outermost zone.
My take is this used oil is still serviceable, yes I know it's already 22,000 km in use.
This Pennzoil Platinum Velocity 5W40 really don't play-play, as our bahasa says.
Strongly recommend this oil to lowyat readers here .
Thank you for posting , Senscents and you're adventurous and looks like in control of situations .

Hi Sir, do you replace oil filter after, say 10k km usage ?

Where you buy 5w30 helix ultra, local all i see is 5w40 version.

Vanli also sells it at slightly cheaper price

nice, thanks

It's good to know that our oil drain interval can be of much longer, ever since i found bitog forum. The forum discuss the EO extensively thw good, bad, extended and normal oil change interval.
It's been slightly more than a year since the last oil change, so it's time for me to change as it recommend so by most sifu out there.
Next change, one of the World recognise OIL. Castrol

Hi. Chemistry, Did not replace the oil filter at 10k, as i find that it will do the job as suppose to.
There are lots of debate out there on the oil and filter change interval, where two camps of people will advise on different effect of the interval of changes.
It's just me and mine opinion that lead me not to change the oil and filter so soon.

Your driving style is easy on oils , in a 2010 City the engine oil should 'well behaved' , but ......

Hi, alphaz ,
Very good blotter spot tests performance, and there is no signs of centre zone perimeter ring developing indicating this oil detergency/dispersancy properties are still in good shape, despite the mileage .
The slightly greyish zone indicates increased level of contaminants and combustion byproducts at 14,160 km which is well dispersed and good .
But that's nothing to be alarmed about as I believe this used oil Helix Ultra 5W30 is still in serviceable condition.
Should the oil be still in use, may be take another blotter spot in 2000 - 3000 km and see how the centre zone goes .....

Hi zeng,

Here's a 24 hour blot test result at 16,000 km, Shell Helix Ultra Fully Synthetic 5w30 Made in Hong Kong, in Elantra 1.8 2002.



It seems to me that it might still be good for another 2000 km I suppose?

Hi alphaz, that's a very robust 16000 km blot.
There is no sign of centre zone perimeter ring (of 8-10 mm diameter) indicating great capacity of dispersancy/detergency of this used oil sample.
Btw, there is some fuel dilution as indicated in the outermost zone but the oil is strong.
2000 km ? I would speculate shouldn't be an issue if you wish to go for it.
Btw, my SHU 5W40 is currently at 16500 km.
Time to locate my 14000 km blotter picture that I promised prior.

i'm also thinking of submitting a blotter, would like to know the sample should be taken when engine is cold or after a drive?

Wkc,
If alphaz sample above was taken after a drive of say > 30 minutes, then the outermost zone or ring indicating fuel dilution may attribute the source of problem to ill tuned fuel injection system, in particular in a carburrettor engine or gasoline direct injection engine.
If the sample was taken cold or < 5 minutes of driving, it's quite normal for most (or any ) engines to demonstrate this phenomenon.Therefore it's hard to point to out-of-tuned fuel system timing as the cause .
Hence it's best to take the blotter sample after driving for say, > 20 minutes to rule out the above 'confusion' .

Hi Zeng..... will appreciate your insight in this blot test. The blot was taken more than 48 hours ago, 15mins after engine switched off.

Since we have seen mostly fully or semi synthetic blot tests, I think we might be curious how ye olde mineral oil will fare Thanks in advance.

EO : Formula Shell 10W-40 SN (Mineral)
Mileage done : 5,466 km since Oct 2018
Car ; Wira 1.6 year 1999

Hi Speedy,
What's the ODO total mileage ? Is it carburrettor or fuel injection ?
There isn't any center zone perimeter ring which is good news for this 5466 km blotter spot test, for it indicates this used mineral Formula Shell 10W40 dispersancy/detergency properties are still in top shape .........
meaning there is still life in this used oil.
There isn't much contaminants as the blotter spot is not darkish or greyish. It may indicate a well maintained engine , never mind it is 1999. IDK.
However I will bench mark this Formula Shell 10W40 against Senscents Formula Shell 5W30 8500 km blotter spot and I would like to speculate they share similar additive package.
Not sure if there is any fuel dilution, as I couldn't 'magnify' the image or see clearly its outermost zone.
I would recommend continue its service for another 2000 km or so and see how its next blotter spot performs.
