I'm wondering how the sample oil is affected when shipped and stored that long in unknown environments. Cold if air flown, then ambient temperature of the receiving country and there's humidity and possibly rough handling? etc.

Is there some sort of protective box or wrapping that comes with the UOA test kit?

modern engine oil are designed (remember the wintergrade viscosity?) to withstand extreme cold temperatures (say, -40c) and not to mention shipping only took a mere few days to reach their labs and got it analyzed.

During the journey the sample is completely sealed with multiple "layers" of containers so that leaks (and likewise, moisture/contaminants getting in) do not happen creating a mess for the postal workers.

refer to mine and bro PedangGila posted pictures of test/sample kits with included instructions.
i personally also wrapped the inner container with pvc tape (which blackstone labs also recommend) to further seal it.

I see. So it's "safe" from moisture and humidity then?

yes.

and do consider using the reply function or the tagging function so people can get notification.

Are you sure that's even necessary? You're permanently camped on LY anyway

not really
getting busier at work and maybe changing job soon.

was just an advice in general (which may or may not apply to me) btw

There's no notification thru mobile site version tho.

Hey guys, this may be answered, but......

Let's say we are comparing both EO are the same.

Which viscosity would you go for with our 1Malaysia climate? 5w30 or 0w40?

xw30 (be it 5W, 10W, etc) should be thinner than the 0w40, right?

as low as possible specified by your engine manufacturer specifications.
personally i will got -10 viscosity over manufacturer specifications.

in other words, as hot as our Malaysian weather is, we don't have constant 40 Celsius ambient temperatures which warrants thicker viscosity.
and yes xw30 is thinner than xw40.
i run 0w20 on my inspira and 0w30 on my iswara/kancil/sentra

for further information, please spend time reading the information on first page.

something to read on in regards to WS2 additives:

Any idea who makes the 0w20 oil for honda??? They insist on using their own oil now during service.......

Blended by Idemitsu.. Honda have just updated their range of engine oil to meet the latest API SN standard. Thus you can have a peace of mind using their oil.

I have a question though.. I noticed their new SN0W30 oil are blended with alipathic hydroncarbon instead of the polyalphaolefin previously used in their SL fully synthetic oil. Any oil guru can enlighten me alipathic hydrocarbon & is it any good?

I just read the conclusion but after missin the page and scrolled through all 100 pages. So it's not recommended this nano additive

the minor + that it *may* have (which is very minimal), is outweighed by the potential corrosion that may come with it.

so yeah with the cons outweigh the pro, it seems not worth it.

It seems like it's base stock got downgraded from group 4 to group 3 (if it's generally hydrocarbon/hydrocracked petroleum base stocks)

however:

so personally i wouldn't be too worried about it.

Thought it was by Idemitsu. I would want to use their oil but they recommend a OCI of 8k for the 0w20....which I think is ridiculous if it's a fully synthetic oil. Am currently running on Mobil 1, just not sure how it would be with the Honda oil....maybe I should give it a go once......

To be honest, I personally change my engine oil at 8k even though I use the more expensive 0W30 fully synthetic. If you google around, most of us are driving under severe driving conditions with lots of start and go traffic and hot weather. Recommended OCI is 10k under normal driving conditions. So I think 8k OCI is quite ok.

What car are you driving bro?

so most of the aftermarket additive is no good? so better just stick to those EO with confirmed API certifications? for example, LiquiMoly don't have API right? i'm still using the one with MOS2, which, MOS2 is also sold as an additive...

btw, bro Quazacolt, since you guys are into EO sampling, have you thought of using an oil suction device, suck out a bit of oil through the dip stick hole, maybe 50-100ml, every 1,000km, so you can have oil sample at different stages?

for what? different stages and keep sending to USA?

and i thought people already call me excessive/crazy for actually doing UOA in the first place.

You ARE crazy.
