Blotter time : 11pm (picture after 48hrs)
oil age : 3,155km
Engine oil used :
Type: Shell Helix HX8 X 5w30

Hi Bro,
You have a very clean 3155 km blotter spot test here, free of centre zone and also free of gray colour zone that relates to contaminants/dirt/wear etc.

I would rank this oil as in Spot 1 with plenty of life in it.



How long you intend to go on this HX8?

Edit: Is your HX8 a SL or SN ?

Hi Bro Zeng,

Again thanks for the detail explanation on my blotted spot test here, appreciate the effort.
The Shell Helix H8 X 5w30 was rate for API SN Plus/SN
For this oil i might try on hitting 10k KM and see how it goes.

Blotter spot 72 hrs.


Absence of centre/deposit zone and its perimeter ring,
...... and going

Anyone can do blotter for Mizu oil?

It is free and easy, everyone can do ownself with a piece of A4 paper or coffee filter , by dropping one drop used oils onto the paper.
No need pay money and kept waiting for weeks ....
Post#1 has some links.

Replaced with similar oil, during Ori oil seals and Ori engine and gearbox mountings replacement .

Wa...your mounting cost quite cheap leh...

Your oxygen sensor rosak?

Not sure if the mountings price is not high ...





Sorry, mistakenly deleted pictures on O2 sensor, before cleaning and after cleaning externally.
Internal can not clean, so mechanic recommend replacement, IDK.
He bought Perodua sensor (same Denso sensor but different electrical fitting) as it is cheaper than 'Toyota' sensor, but used back my old fitting.

Below are the 2 oil seals,

Yes, fuel consumption increases from 11.5-12.5 km/L to 9.9 km/L despite similar tyre pressure of 44 psi.
Computer reads old (wave oscillations) readings between 0.1 and 0.6 in Volts(?).
After sensor replacement, back to specification of between 0.1 and 0.9 , again pictures wrongly deleted.

Edit:WKC, will find you a Shell Helix HX7 5W30 virgin oil analysis.
You used SL or SN ?

The HX7 was the free engine oil provided by the dealer under free maintenance programme, don't know which rating was given, but assume is SN.

Where did you get this VOA data? Did you do it or from oil-club.ru?

From the russian oil club, sir .

Here it comes ....

Hope it helps .

noack 6%??? and TBN of 10, pretty insane

Testing ada salah kah?

Or am i reading it wrongly?

To be honest, I was taken aback too when first came across this voa results.

From my readings around, VOA testings in Germany/Russia is more sophisticated then that in NA like Blackstone etc.

I don't doubt the 'ball park' figures in this test, though Labs do make mistake occassionally and there is always a margin of error in any lab testing, hence the requirements of periodic calibration of lab equipments.

I'd used HX7 10W40 before but not its 5W30 siblings, and I must concede this Helix HX7 5W30 SN is a quality engine oil in relative terms to other 5W30's .

Shell's GTL basestock is well known to hv very low NOACK figure, not surprising in this respect at all. just that i didn't expect they use GTL base in a lower tier SS oil.

noack of 6 is very damn good for a semi synthetic product, the baseline for SN if not mistaken is about 12-13%, so this is insanely good with a 100% margin from baseline!. Even many top tier fully synthetic can't reach that low of noack value at that viscosity range, only a handful that i know of, namely mobil1 esp (5.6%) and ravenol dxg (6%). Others like the venerable amsoil signature synthetic is 7.8% for 5w30. Even these top tier fully synthetic are around of 7-8%, some surprisingly at the higher end of 9%.

On the other hand, pennzoil platinum ultra and helix ultra ect c2/c3 (also using shell's GTL), is 9%+ noack, why leh?

Agree with you on the use of GTL base oils in this HX7 5W30.
IMHO, technically it is a fully synthetic oil but somehow marketed as semisyn.
It's really a good bargain for buyers.
