Please be informed that some garages and Indy workshops are being advised to put the wrong oil in our vehicles by there suppliers.
If the AXD/AXE has the wrong oil in it can over time destroy the engine. It MUST be vw 506.01!
Putting the wrong oil in this engine in error could be why this engine has now got such a bad reputation.
I read the sticky thread ( which oil) last night and it made me wonder if my Indy was using the right oil in my van, so I popped in and asked them. They rang there supplier, quoted my reg number and they advised the wrong oil!
So they are changing the oil for me on Saturday.
So please read the which oil thread, and make sure if you don't change the oil yourself that whoever does it for you puts in the vw 506.01.

people will do what they think best....even vw dealers don't know. TPS couldn't care less either. It's a pity VW can't put a stop to all this but I guess they don't really CARE either. Not subscribing to conspiracy theories particularly however the more damage their customers cause by ignorance/confusion etc the more parts VW sell.....seems a perfect combination

the only suitable oil available here is 507, so its academic!!! that's clearly the future and its as cheap as 38 euros for 5lt..
- lol, you've not read anything everyone has said. unless you have some constructive & factual points, perhaps bow out. or at least read the factual evidence thus far, then you will see 507 isn't better, it's different, it has the same properties as 504! the polar opposite to 506.1

regardless, this thread is now a broken record, unfollowed

Advice Not on 507 but which oil???
In my handbook it says to use 505/01 for non long life PRno QG0 or QG2, If long life VW 506/01 where PRno QG1. I am not sure where i find the PR no or what it is!!! The engine is AXE in a 2004 174bhp caravelle.
TPS and therefore the garage are saying use 505/01, 5W40 it is due an oil change can I have some advice please always trusted the garage but just i guess want some confirmation and can mine ever go on long life service intervals???

Thanks in advance

:confused::confused::confused::confused:

There is nowhere in Vw service books that says use 507.00 in axd/axe engines only what dealers tell you unless you ,ve got something in writing to prove differently . Variable service intervals are probably the biggest cause of camshaft failure but even so if your dealer could put it in writing ,it,d be good

507 oil works perfectly well in axe axd engines full stop. My 35 years of experience repairing vws tell me that the biggest problem is cleanliness of oil and engine oil galleries etc. 507 should be backwards compatible, prove to me it isnt. I never let mine go over 10,000 km between oil changes and if oil is deteriorating ichange it early. If you work in the commercial world oil is analysed everyfew weeks and changed appropriately. Themoral of the story is check every fluid regularly on these vans.

So if your on long life then your saying its bad and needs changing every 10k regardless of which oil:* whether its 506 or 507 it will still get a heavy carbon deposit in the oil which will affect the life of the engine :confused:
 
#71 ·
What i am saying is that the more often the longlife oil is changed is better for the engine as you get more out quicker and engine has fresher oil as these engines are fussy . Personally i am not a fan of huge service intervals for lots of reasons. If a non longlife oil to the right spec was available i would probably use it and change even more frequently.
 
#77 ·
Correct me if I am wrong but I have concluded from this thread that although 507.1 is o.k. to use with no proven detriment to AXE or AXD engines, some experiences have caused people to suspect it MAY cause cam wear.
Would it not be reasonable to conclude that for these engines it would pay to err on the side of caution and use 506.1 and change it more frequently?
Again consensus seems to suggest that 10,000 km would be a good frequency or less if Urban or stop start driving is your practice.

In my AXE handbook it states that 507.00 is fine for DPF systems and 506.01 for non DPF.
 
#79 ·
I think that's a fair conclusion but mine and others went into limphome when under load when using 507.00 and it has not gone into limphome once since running 506.01!
I can also confirm the van runs smoother and quiter on 506.1, it has never ran as well as it is doing now.
The r5 2.5 tdi engine was quite an advanced engine when it came out with its alloy block and crossflow head and the best oil at the time made for that engine was 506.01.
507.00 was designed after the r5 2.5 for engines with dpf and like it says on tin not for the r5 engine.
So we are given a choice of oil, one we know that works or one that may not......I know which my choice is 506.01!
I've invested a lot of money in my engine with a big turbo ect and want the best oil available for it.

Hi all,
Maybe I can put this to bed (for AXD at least). My van is a 2004 2.5 AXD

I read through this whole thread as I wanted to be sure I was going to put the correct oil in. There seems to be lots of comments from people saying that 507.01 is ok, but with out many facts, to be honest my gut feeling is that my van should be running 506.01.

Long story short I contacted VW Customer care, explained about using the forum and my concerns regarding cam wear, gave them all my details, chassis number, reg number, even mileage. They were very helpful, they left me a voicemail (annoying that I missed the call!) as well as an email.

(I know that he only quotes my reg no in the email and obviously in previous posts people were saying they have been misinformed by going off of the reg but in the voice mail he quoted my full chassis number.)

Any way this was their response direct from the horses mouth.

Thank you for contacting Volkswagen Commercial Vehicle Customer Care. I have attempted to contact you by telephone but have been
unsuccessful in doing so. Please accept my apology for the delay in my response.

I can advise that the correct oil specification required for your vehicle registration CU04BXB is 506.01. This item can be purchased
from your local Van Centre details of which can be found at www.volkswagen-vans.co.uk, using the Find a Van Centre option.

I hope this information proves useful.

I own T5 2005 AXE. And I use the newest oil available SHELL 0W30 HELIX ULTRA ECT C2/C3 507.00 and I add half of bottle Redline Engine Oil Break-In Additive (ZDDP) for cam wear on every oil change. I change the oil once a year or after 15000 km.

506.01 oil has more ZDDP than 507.00

From Redline:
Half Bottle (8oz.) when treating:
Capacity - Phosphorus - Zinc
8 quarts - 572 ppm - 690 ppm

Just phoned VW Van Centre in Heathrow, they confirmed my 04 T5 2.5 AXD does definately need 506.01, they said they had lots of problems with people putting in 507 00, had quite a few engines needing new camshafts/rebuilds!

Found the info below on a Toureg forum, it may have been mentioned before, but only managed to read up to page 17 on this thread, then brain melted!!!:eek:

Posted 10 January 2009 - 03:18 AM

Noobs, I found this on a Castrol website

ZDDP additive (zinc dialkyldilithiophosphate) provides a high level of anti-wear protection, but it's phosphorous content is harmful to catalytic converters and other emission equipment eg DPFs

I therefore surmise that the injection pump drive from the camshaft on a 2.5 or 5.0 will benefit from ZDDP to reduce wear, so use 506.01.

But the later engines have benefitted from the latest surface hardening technology, so can get by with more friendly additives, so 507 oil will have less ZDDP so as to be suitable for emission equipment.
And from Russian forum (oil club): http://www.oil-club.ru/forum/topic/14974-shell-helix-ultra-ect-c2c3-0w-30-svezhee/page-1
They made an analysis for Shell 507.0 oil and found how much Phosphorus (699) and Zink (838) it contains.

There is another comparison for 506.01 and 507.00

I see you found one of my old posts:), your right 506.01 does have higher ZDDP and SAPS compared to the later 507.
These additives can help protect flat tappet cams.
I use Fuchs Pro S in my AXD.

Lots of people in the US are using Mobil Delvac and Shell Rotela in there VAG PD engines and have showed much lower wear numbers on oil analysis compared to OE oils.

I have to laugh at this endless debate.
So many opinions.
From what I've seen, The VW designers that signed off on this engine, designed a fundamentally flawed engine.
Oil supply to the head is insufficient.
Cylinder #5 s itself for no reason.
The head cracks probably due to heat not being drawn away by the oil(insufficient supply).
The cam knackers itself.
The sump baffle shatters......and so on.
Bad design/cheap material.
Apart from the dpf friendly oil, any decent engine should last longer than 120k miles no matter what oil you use(within reason) and change it often.
Example: 200hp Honda Fireblade engine running semi synthetic oil because the clutch slipped less, thrashed around the Isle of Man, practice and race week and a full seasons racing, finished off with a visit to the Macau GP. Engine stripped with no noticeable wear.
Fresh good oil.
Simple.

Gulp! - thanks a lot Cathalp. That's v depressing for us lot who have AXDs. I've had a 2006 AXD since it was 10 months old, & loved it's torque (needed for 4Motion), power & smoothness. 133,000 miles & v few probs so far. Intercooler split couple of months ago, & I agree stupid that the 3 vertical straps can rust so easily. I can see the thin steel manifold but mines OK & rest seems OK.
So, even if you're right & I've just been lucky or have bad news just around the corner, what would be helpful for us apparently AXD-lumbered if someone could tell me, for when i have to change vans:-
- what are the pros & cons of the 2010-onwards 2l/4cyl engine? (I've read about the oil usage probs of the 2010-2012 180bhp vans - what else is good/bad on other versions?)
- is the 2007-2010 BNZ engine much better than the AXD? - I'd thought of looking for one off these with less miles as one possibility
- if not VW, what's a better van? (drivability plus reliability) - new or recent, if I decide to spend more money on a new or near new van.
The real prize would be an alternative to the 4Motion, but no such other van seems to exist (in the UK, RHD).

The design isn't ideal but VW didn't really have much of a choice, to fit the PD cam lobe on the cam they had to narrow the inlet and exhaust cam lobe's to fit it in. Now the face to face loading on the inlet and exhaust cam lobe's/ followers is higher due to a smaller surface area and this can cause additional wear.
