VW 508 Spec-0w20

I noticed both the Motul and Liqui Moly 0w20 oils that fit this specification both are primarily PAO from safety data sheets. I wonder if that base stock is needed for this oil because 95 percent of Motul 8100 oils seem to be group three based on safety data sheets and most of liqui moly oils are the same. I also noticed Castrol Edge professional 0w20 that fits this specification also has between 25-50 percent pao basestock.

I apologize for bringing this up in case it has already, but there are so few 50800 approved oils for the EA839 engine (the engine in question in VW/Audi/Porsche) that this engine oil is used for. That said, it seems like buying Castrol Professional LL IV FE is the only way to go.

NOACK is something I am interested in for this oil due to the DI application of the 839 motor. Does anyone know what that value is?

None currently. Those are fairly new oils and used primarily on North American market. NOACK is not published by many manufacturers and it will take some time to get numbers.

I was fearful of this but good to know, thank you.

Is it a relatively accurate comment for me to state that "Mobil 1 0w40" most probably has a lower NOACK value than a 50800 0W20 oil simply based on reputation and thicker viscosity with the former, or is there absolutely 0 correlation?
 
Or, better yet, does anyone know the NOACK limit for a VW 50800 specced oil?

Eg coming from the MB world, I know that 229.5 has a 10% limit....I know close to nothing about 50800 so hoping to gain some more info if anyone has it.

Short answer: No.
 
Here are three other 508 oils:

https://catalog.lubricants.total.com/en/products/fm9/QUARTZ-INEO-LONG-LIFE-0W-20
https://www.mobil.com/English-DK/Passenger-Vehicle-Lube/pds/GLXXMobil-1-ESP-x2-0W20
https://products.liqui-moly.com/top-tec-6200-0w-20-12.html

SDS seem to indicate all are POA based. So the important differences are the add pack. I did a VOA of the Castrol here: https://www.bobistheoilguy.com/foru...ro-oe-lliv-fe-0w20-for-vw508#Post4876875

Seems fairly simple other than the Titanium. Does anyone know the add packs of the other product lines? Let me know if any of these are available in the US, I'd like to get some VOA's done before my next oil change to help me decide.
 
Can you explain what is important about the add pack? What makes one better than another? Can you tell from a VOA or UOA which one is better than another?

Even if I had the expertise, the VOA doesn't tell the whole story...but from following UOA here for years, it does seem like the ones with some Boron and Moly produce better results. For what that's worth. But it does seem a fairly consistent data point. PU with both produced significantly better UOA for my 370Z than Castrol with Titanium did for example.

Another thing is the detergent and the low speed detonation issue. Castrol hasn't moved towards Mg based on the VOA above, but then the levels aren't terribly high, so maybe not a big deal.

I am vaguely aware of the low speed detonation issue. What oil properties am I looking for that helps with this? I presume the Castrol 50800 oil is not ideal to ward off low speed detonation?
 
Here, we call it pre-ignition, versus this.

Happy New Year, Everyone! I was gone for a bit as I just retired from my G-Job in November, since then We've been dealing with family health issues and hospitalization.
Anywho, I just traded my old 2014 Rogue for a ugly markVII VW Jetta S 6M. I said to myself - before any research - that "at least I dont have to deal with non synthetic light grade oils in this engine - being an overstressed 1.4T". Ha I guess I missed guessed here
smile.gif
It was nice to see made in Germany Engine and Transmission. This is a VERY refined ride. Lots of Tech even on the base S version I pretend its my wife's old 240D from the early 70's
smile.gif
I only have a 2 year 20K mile lease but I will likely wish to do a ~ 5K mile initial OCI. The facpry rec OCI is 10K miles or One year. If the VW service wont do it, I will do it. I Dont have a feeling what the engine wants yet. Only have 62 miles on it. Noticed the oil temp running around 205 F after about 15mins around town easy driving in 35 degree weather. Seems about right. Any Ideas on oil and filter?
BTW I used the New Valvoline 5w30 "ADVANCED" synthetic in the Rogue ( with a larger Fram TG spec for Titan V8) and it LOVED it; Very impressive stuff and killer add pack. Pre-oiling the filter 50% it appeared and felt as Golden dew of the gods. NK!

Good to be back. I promise not to be a pain now Im in a lower stress environment.

See signature. I know from past experience that my conditions tend to be easy on oil, setting aside application.
I intend to go for extended OCI's and UOA's to see how far I can stretch it out. So far, I am very happy with the Castrol. It is Group III per Safety Data Sheet. I will watch for oxidative thickening, and keep in mind that "TBN is not linear." The Castrol is made in Austria, has a foil sealed cap, and has VW 508.00/509.00 as the one and only certification on the bottle. It is also half the price of Motul.

All the best with your Jetta, Sir.

I have seen Total oils on Amazon, otherwise no idea.

Interesting as this is the exact oil my local Mazda dealership has used since 2011 or so. Green 0W-20 Castrol professional LL FE.

The details are important. The Longlife IV spec (VW 508 00/509 00) is only a couple of years old so nothing was being sold for it in 2011.

I would bet money VW wrote the spec around the oil. The oil hasn't changed.
