Goodbye 505.01, Hello Delvac 1

[GMARK]

O.K.,
The warranty is gone, and with it the 505.01 nonsense. Today I'll be switching to Delvac 1 in my 2004 PD so you all can stand by and watch my engine self-destruct. I'll take one for the team, so follow along and see what happens. I plan to do regular oil analyses starting with a sample at around 3k. Any comments? I'm wearing my nomex suit.

[BleachedBora]

First off, regarding your signature--we do appreciate you serving us.
Second, I recently switched FROM Delvac to 505.01 oil--partially because it's cheaper, and partially because I'm curious to try it...interesting how the tables turn!
Anyway, good luck, hope you have armor plated your engine bay for when the engine explodes!

Here we go. Do a search on PD cam failures. There are cases on record of premature cam lobe wear from not using 505.01 in a PD. VW did not specify this oil to make money off of us lowly citizens. The PD engine has been sold in Europe for almost a decade now and 505.01 oil is widely available there. This stringent oil requirement does serve a purpose. It's a pity you just don't see the light on this one...

Absolutely agree...don't do it...unless you want to replace internal engine parts...

I have used Delvac 1 in my '03 exclusively up to this last oil change when I filled with Motul 505.01 to see if there is any difference in wear (I have the flexible service mod).

This guy has clearly made the choice to sacrifice his engine in the interests of science. We don't need to remind him 50x about this, it sounds like his mind is made up.

I am very curious to see the results however. If you do go through with this, please keep us updated, despite the 50 people that will tell you to watch out because your engine is going to explode.

Worst-case it will grind the cam down, and you will need 4 injectors and 1 cam. That isn't _THAT_ expensive. Good luck!

[Reggie]

Exactly,

Let the results speak for themselves. The man said he was going to do analysis. I would also suggest taking the valve cover off and doing a pre-Mobil 1 photo of the cam lobes.

Good recommendation at a minimum.

G, I salute your bravery! Please keep us posted - - several others have embarked on an identical mission. I do not believe we have ever heard back from any of them.

Did you know that less than 20% of all oils submitted for testing against against the 505.01 standard actually pass?

Good luck on your mission!

This scene has been taking place an awful lot lately at our Mobil Store..
A very new looking TDI drives up, the driver gets out with a grin on is face and says "I'm back George! The warranty is over on my TDI and I am finished with that XXXX oil and back to Delvac 1". So far all oil analysis results I have seen have indicated a decrease in wear metals, etc.. I would very much like someone to share how a full group IV synthetic 40W is going to cause cam issues, especially with its robust anti-wear package to boot, vs. a group II+ or Group III containing far less addization... Please enlighten.. I am missing something......

I don't recall seeing these. Can you/or someone else provide a link? Thanks.

must be a VW conspiracy to force PD owners to buy from the dealer..

[childishidealism]

GMARK,
No one seems to be asking the important question. Why? Can you get the Delvac 1 cheaper? Do you feel it is superior to the 505.01 oils? Is it just because you think the spec is nonsense? Unless you are getting the oil for free I just really don't see why you could want to do the experiment. Please enlighten the rest of us.

[Fait_pour_TDI]

GMark for what its worth I recently received an email (sorry would pass it on but it is in french) reply from a Petro Canada chemical engineer (PetroCanada sell a synthetic 5w40 as well here) which is NOT 505.01 certified.In the email he informs me that the difference between 505.00 and 505.01 is simply a volatility test.He claims in his email that his Duron 5w40 would pose no problem used in a 505.01 application.BTW Delvac1 is not 505.00 certified but I have (as many of you also do) been putting it in my engine since I bought it and it certainly has not damaged my internal engine parts.Keep in mind that oil companies have to pay to get their product approved by the various manufacturers, some go with standard API test while others have specific test of their own (Cummins,CAT,etc).Oil companies that sell their product on this side of the Atlantic most likely evaluate the market share and determine wether the expense of getting to put an extra label on their bottle is worth its while (we wouldn't want to cut Mobil's profit margin down).PD technology is not exclusive to VW, Caterpillar engines have similar type injectors and I dont think Delvac1 ruins their engines.

Actually there are plenty of places that sell the oil for a lot less than the dealer.

What Mobil product does Mobil recommended to put in a PD?

Here are three of them:

tisches Hochleistungsmotorenöl speziell für
PKW-Benzin- und Dieselmotoren der VW-
Gruppe. Hauptziel bei der Entwicklung dieses
Öles war, die Anforderungen für verlängerte
Wartungsintervalle zu erfüllen und gleichzeitig
einen bedeutenden Beitrag für die Kraftstoffein-
sparung und die Motorensauberkeit zu leisten.
Mobil SHC Formula LD 0W-30 wurde entwickelt,
um die neuesten Anforderungen der VW/Audi-
Gruppe bezüglich verlängerter Oelwechselinter-
valle in Verbindung mit der elektronischen Servi-
ceanzeige zu erfüllen.
Anwendung
Mobil SHC Formula LD 0W-30 ist ein Service-
und Nachfüllöl für Fahrzeuge der VW/Audi-
Gruppe
mit
Wartungsintervallverlängerung
(Longlife-Service), wenn Motorenöle nach VW-
Norm 503 00, 506 00 oder 506 01 gefordert sind,
also auch für die Dieselmotoren mit Pumpe-
Düse-Technik, die für Longlife-Service vorge-
sehen sind. Diese Fahrzeuge werden bereits ab
Werk mit Motorenölen dieser Qualität befüllt. Für
den Einsatz in anderen Fahrzeugen ist das Öl
nicht vorgesehen
.
Eigenschaften / Vorteile
• Die vollsynthetische Formulierung erlaubt die
Verlängerung der Ölwechselintervalle in
VW/Audi-Fahrzeugen mit Wartungintervallver-
längerung (WIV)
- bis 30 000 km in Benzinmotoren oder 2 Jah-
re
- bis 50 000 km in Dieselmotoren oder 2 Jahre
- bis 30 000 km in Dieselmotoren von Trans-
portern oder 2 Jahre
• Die niedrige Viskosität erlaubt hohe Kraftstoff-
einspareffekte und damit Entlastung der Um-
welt.
• Hervorragende Tieftemperatureigenschaften
gewährleisten eine schnelle Durchölung und
damit verbesserten Verschleiss-Schutz beim
Kaltstart.
• Exzellente thermische und Oxidationsstabilität
bieten Schutz auch bei hohen Temperaturen
und über den langen Wechselzyklus.
• Die Ausdehnung der Wechselintervalle ver-
mindert den Ölbedarf und verringert den Altöl-
anfall, was zur Entlastung der Umwelt führt.
