I had been monitoring UOA's of fully synthetic ; semi synthetic and mineral oils in America ......
and read-up on Blotter Spot tests method online .....
and hence pushing for longer OCI's which may be deemed as 'uncharted waters' .....
as a contribution to lowyat forum. blush.gif

Edit:As of today, touching 14900 km ...... and going.

Sorry for misrepresenting XL 0W30 as fullsyn oils.
Generally dual rated HDEO oils is more stout than PCMO oils, I believe.

Hahaha ......> 14 months usage ........
so much for the myth here that engine oil must be replaced at not more than 12 months.

At 12000 km OCI, appreciate if you could upload here its Blotter Spot Tests pictures for comparisons. dry.gif

Kindly observe colour of drained oil as used HDEO oil tends to be blackish or grayish, though still serviceable.
Btw, your engine comes with timing belt and not timing chain right?

OK, will ask the foreman to keep the used Oil Filter for me biggrin.gif
GA16 uses timing chain.

My understanding of timinig chain is it shears oil viscosity in use, probably up to 10,000 km or so.
With 'life time' timing chain in my Avanza K3VE, xW40 is my go-to oil, among other operating conditions.

Most of the oil shearing are at the high pressure areas like the cam lobes, valve heads/rocker, crank bearings, crank journal, etc. If don't explore much rev above 4000rpm, most of the oil degradation is from the depletion of the additives, not really due to oil shear.

Yup gonna change to Duron XL 15W40 soon.

This motor prefer high SAPS oil.

Done oil change just now. Labour RM15.
Observed colour of drained oil, it was dark brown.

Haha, ya, RM15 is considered as minimum labour charge nowadays. Somemore got free checking air filter, coolant level, brake fluid level, power steering fluid level , although I myself can check too.

UOA's of black coloured (including those with dark hue) used oils on Bitog do often indicate continuing serviceability of said oil with good/low metal wear rates, Flash point, TBN, insolubles etc.
Plus your uploading of Blotter spot tests before this, I would speculate this dark brown coloured used oil is probably still serviceable.
Engine varnish, if any, in itself is not a sign of definite engine failure.

Agree with you.....
and timing chains and turbos do contribute to viscosity shearing.

QUOTE
As you know, mechanical shearing occurs at several common locations within an engine and it can differ from engine to engine based on the hardware design, In my opinion, most of the shearing occurs in the valve train and the timing chain/gears.

Yeah I think so too , but given the oil already in service for 17 months, i think it already well reflected its value biggrin.gif

so does that mean Quartz Energy 10W40 can be used up to 16k ?

Without knowing your engine type, its mechanical conditions, your driving pattern etc , my short answer is no .....
assuming you're in the typical league of early oil change (like mineral oil for < 5000 km; semisyn oil for <8000 km and fullsyn <10000 km) as Insurance , peace of mind bla bla bla.
Heck, most of you guy's oils are without ACEA A3B4 specifications! ..... never mind it's fully synthetics.

Do note Quartz Energy 10W40 has favourable specs in ACEA A3B4, among others like API, VW and MB for components protection.

I've stacks of fullsyn like Shell Ultra 5W40 and Mobil 1 0W40 ..... likely OCI in this (Japanese) engine would be 18000-20000 km...... in times to come.
