To support my contention above , attached below is a chart demonstrating the phenomenon of
increasing engine Coefficient of Friction,
with decreasing ppm(parts per million) of Molybdenum additive ...
in a typical engine oil application which likely applies to this application of HX8 5W30 of voa Molybdenum 39 ppm .

repost here.

daikor zeng, tolong...

which one better? I want to get to for my next engine oil test.

hx8 x better i guess. i no expect.
but hx8 is only SL spec.

Any promo currently at hypermarkets fot hx8 x? Want to get 2 bottles.

hypermarkets only have hx8 la
but i dunno got promo or not now. nowadays the promo always run together with shell helix ultra 5w40.
same price punya.

Sure , your pleasure .

The Centre Zone of about say, 8 mm has not heavily darkened and became opaque, hence it has not formed yet from the agglomeration and coagulation of combustion products .

The Perimeter Ring of about say, 10 mm annulus ring surrounding the Centre Zone has not formed or visible with darkened colour.

Both the above shows no trace of agglomeration and coagulation of combustion products in this Urania LS mid-SaPS HDEO at 5000 km .

The complete circle of Outer Diameter 20 mm of light grayish colour indicating quite an even distribution of all the dirts and contaminants of combustion .

Exterior to the above 20 mm OD circle shows light yellow colour and looking transparent, indicating very low level of contaminants and dirts in the used oil .

Overall, this blotter spot indicates the detergency and dispersancy properties of this 5000 km used oil is still in tip top condition . IMHO it is still serviceable for another several thousands of km .

Btw, this mid-SaPS Petronas Urania LS 15W40 has a very powerful specs in CJ4/ E9 etc .



Note:May I know the (petrol) engine type in use here and its current odometer readings ?

What your comment on normal car using hdeo?
btw i use this car for street race,little modified here and there, sometime redline till rev limit, gearbox manual

I have been using HDEO 15W40 in my wira and Avanza for many many years .
HDEO's are fine for non-Euro petrol engines, IMO .
CJ4 HDEO's is smart selection in your 'harsh' context , and you appear to be well informed .

Note:Lately I switched to readily available semisyn and fullsyn 'PCMO' Euro oils for its frequent promotional price .

zeng, what is the km interval for this oil? interested to try this out !

Before semisyn and fullsyn, I have been on Petronas Supremo CI4 15W40 for several years at up to 9000 km .
This 3000 LS is mid SaPS in CJ4, which is slightly higher spec'ed than my previous CI4 .
Personally, I have no qualms going for 10,000 km oci or more and comfortable about it .
Your comfort level may vary though .

Any comments on the Syntium Fully Synthetic 3000 series 5W30 oil?

If you mean the local Petronas version of Syntium 3000 series 5W30 , it has stronger spec (than SN/SM) in Dexos 1 Gen 2 .
GM approves this oil up to 10,000 miles (16,000 km) oil change intervals in States .

If you mean this imported Petronas Syntium 3000 FR 5W30 , it has stronger spec (than SN/SM) in Ford 913D specification .
Ford US too approves this oil for up to 10,000 miles (16,000 km) oil change intervals .

In Asian/US engines, use these 2 oils with peace of mind even with above stipulated oci .

Thanks for the information.. Guess I'll be switching over to Petronas Syntium for my next oil change.

Honda City Gm2 year 2009
Current Odo : 121,181
Date: 22/02/2020
Blotter time : 11:00am (picture after 44hrs)
oil age : 11,933km
Engine oil used :Shell Helix HX8 X 5w30

Got my oil change after finished the blotter spot test.
current oil was Amsoil Signature 5w30
will update the oil after 3000km

Hi 90Boyz,

Thanks for sharing .

There is no sign of fuel dilution problem , as seen from the absence of outermost translucent zone/annulus .

There is also absence of darkened centre zone (of about 8 mm diameter) and absence of perimeter zone (of about 10 mm outer diameter OD) ,which are good news, probably due to a very low level of combustion contaminants and still-high performance levels of detergency and dispersancy of the used oils .

The very slight grayish and light colour of the Diffusion zone indicates very low level of dirt/contaminants after 11,933 km usage , with very high level of residual detergency/dispersancy capabilities of the used oil .

I would speculate the internal cleanliness of this 2009 Honda City engine is very clean and /or this HX8 5W30 is performing in top shape/form ,or both .

IMHO, this 11,933 km used oil is still serviceable and fit for continuing service .

Yes, I'm aware you'd replace the oil with Amsoil which is another good (but expensive) engine oil .

Thanks bro Zeng for the details
wanted to try on Amsoil for quite some times with alot of review in website nor with the youtube channel.
so far initial impression was very smooth and quiet engine for now.
let's see how it goes along the way

Amsoil Signature 5W30 has a substantial and high amount of Molybdenum and Boron additives .
That probably helps with the bold above .
