Hmmm that is bad. Any source to this claim?

heard this from 2 workshops while when doing my distribution trips to my regular workshops. just check your EO regularly, if it is recycled oil, changed it out and do engine flush.

Aren't most oils of up to 50% are recycled oil? At least that is what i read.

"In Europe, about 50 percent of motor oil is re-refined, thanks to regulations dating to 1975 that were revised in 2008, say analysts at Kline & Company, a market research firm based in Parsippany, New Jersey. In North America, only about 10 to 15 percent of motor oil is re-refined." Source
Personally thinks that recycled oil if process stringently, may be as good as new with the technology up to date in refining.
My concern is on the HKS oil if it is a quality oil that protects, lubricates and cools engine down and not forgetting, not so prone to causing gunks.

You sell oil btw? haha, thanks for the headups, good if you can provide more details on this, I'm contemplating to switch it out, but year end finance a bit heavy. >.<

Most oils even the reputable brands, Valvoline in particular (and they advertise this) recycle their oils especially the base stock for environmental purposes.

In fact, for an engine oil to be properly recycled and having all its additives restored is an even more expensive and tedious process than just using raw materials.

The only problem lies when fake oil /unethical sellers does it as it definitely won't be done proper and the oil properties /additives will be lacking to properly protect your engine.

If you want to be safe, just go with reputable brands that are api certified (again, their website can be publicly queried) or even consider VOA/uoa (virgin /used oil analysis).

yes if the oil are recycled in a proper manner, it is safe, but here we have people who collect used "branded" oil bottles and cans to repack the recycked oil, which is fake oil. i know coz many workshop do sell those used bottles for 50 cents to 1.00 ringgit depending on the brands, just check your EO weekly or daily, i was told you will feel the effect around 1k km or so. and yes i am into the lube industry carrying this Magna lube.

probably futile, but if anyone wants to send oil samples to BSL, i am preparing a shipment soon, i got 3 samples so far.
let me know if you want to send/share shipping

in case you're interested shin

yesterday managed to service my toyota camry 2.0e with liqui moly synthoil premium 5w-40 ... this is my first time using liqui moly lubricant , i must say this is one of the best so far .. engine feel more lighter , smooth and quieter ... for me its expensive but worth it

Wrong timing, baru service not long ago

Ah damn. I haven't extracted my oil yet. It's not due for another 3000km.

if you want, you can always keep the drained oil in a sealed container and wait for the next shipping.
my oil has been in storage since 2-3 months ago

Suck some up from dip stick hole.

1. Buy a small plastis tube / pneumatic tube that can feed into the dip stick hole, and long enough too to reach bottom.

2. One end ofcourse insert into the hole, the other end insert it to a unused shampoo/hand sanitizer's pump. Ofcourse you need to clean it thoroughly.

3. Begin pumping!

Thats how i pump my excess/overfilled ATF out last time lol. But since you guys purpose is UOA, you need to consider contaminant from the make shift pump, and cleaness of the plastic tube.

I haven't found a pneumatic tube pump that can extract oil from the top. Any recommendations?

And you're right about the contaminants, so will have to do what the quazcolt said, drop, sample, seal and keep for next round.

this plus this

Dude, you're a bloody genius! Ok will try that tonight

postage delayed 1-2 weeks waiting for a friend that just gotten a used E46

I just checked the engine oil condition for my cars back home.

1) 13 year old vios with 215k on ODO. Last oil change was 10k km ago, used tesco fully synthetic (topped up a little 2 months ago with shell helix hx7 due to some oil consumption), colour looks like dirty cooking oil, strong petrol chemical smell but no burnt smell.
2) 4 year old santa fe diesel, 70k on ODO. Last oil change was 4.5k km ago, used shell helix hx7, colour comes out black, no burnt smell.

Question :
Is it normal for diesel oil to turn out in that condition after just 4.5k km? This car has gone through regular servicing in hyundai service centre and engine flushing was done for alternate oil change interval.

Does this mean that i have to use engine oil with stronger detergent or API rating? Shell hx7 is rated for API CF though.

wouldn't be too surprised. there is a reason why diesel EO are HDEO after all.
consider an engine oil with the latest API diesel service rating (CI/CJ)

that said, when using the latest CJ rating EO, do check if your manufacturer manual recommends it (eg: API "Cx or greater")

Hmm...that means i should really consider using other engine oil brands.

Do you know of any brands that carry 10W or lower viscosity in at least semi synthetic form in our local market for CH rating or above? What i found in my initial search are mostly mineral based with 15W viscosity.

If really no choice, was thinking of getting Bardahl C60 diesel engine oil.

generally, ignore the number before w, as that's for winter grade/winter viscosity.

refer back to your owner's/service manual
