I'd have to see the writing on the bottle with my own eyes before I'd believe it. The web site says only "Recommended for Applications Requiring the Following Specifications:" and then lists the OEM specs.

And I'm quite sure that Amsoil does its own testing. I'm also quite sure that's completely irrelevant to passing the OEM tests that other oil must pass in order to carry the OEM ratings.
 
GMan II,

If Amsoil lists an OEM spec for one of their engine oils, it means the additive chemistry they are using in that particular formulation has been tested - typically by Lubrizol - in that formulation.

Provided your basestock and VI modifier are of sufficiently high quality, passing these tests is mainly a matter of using the proper additive chemistry. Oil companies don't usually test every fully formulated oil they make in every one of these applications. It is the additive companies that bear the brunt of the cost of standardized testing. This is why they'd like to eliminate the API licensing program altogether and go to the European system where the vehicle manufacturers set the lube standards.

With API specs changing every 2-3 years, it is very hard for Lubrizol, Ethyl, Infinium, Oronite to recoup their testing costs simply by selling approved additive chemistries.

Ted, it's the European OEM standards (e.g. MB 229.3, VW 505, etc.) that I'm talking about. These (and others) are what's listed on Amsoil's web site where they use the "recommended for" language and don't say that the oil actually "meets" any of these standards.
 
Specs for Castrol, VW 505.01 Oil:

Vis @ 100C ...14.4 Cst
Vis @ 40C ...95.3 Cst
VI ...156
Pour Point ...-60F
Flash Point ...+440F
CCS viscosity @ -25C ...3400 Cp
TBN ...10.2
Sulphated Ash ...1.2%

Looking at the vis @ 100C and the VI of 156, I'd estimate the HT/HS viscosity @ 150C to be in the 3.8-4.0 Cp range. Given the pour point and CCS viscosity, it's probably a PAO/Ester based oil.

I understand that VW/Audi are also recommending this oil for some of their newer gas engines like the Audi RS6 and the VW "W8".
 
"on the first link and could find nothing wrong with the series 2000 2-stroke oil."
They are claiming series 200e meets tcw3 and jaso fc specs which it cant and in the case of the atf they are saying its ok to use for atf+4 applications and dexron applictaions which 1 fluid can not do because of the fact that they have differant frictional charachteristics.
 
Hello all. This is my 1st post in this forum. I work at a VW/Audi dealership as a parts consultant. The Castrol 505.01 oil in question is VW part# G052167A2//MSRP $7.65 per liter. The oil is currently available through any VW/Audi dealer. The only vehicle we've used it in so far is the Audi RS6. Actually, that price just came down in the past week. The MSRP was $12.35 per liter only a few days ago. I just wanted to say that I've been browsing this forum for a few weeks and soaking as much info in as possible. You folks have showed me that I most definately have a lot to learn, and I thank you for that.
 
I wrote Ed K back at Amsoil, and told him I thought his answer to be unsatisfactory. I am a dealer, and I think all Amsoil's products are first rate. I will not flush my integrity to sell a few bottles of oil to somebody, especially when it may be their first VW, first diesel, or first Amsoil purchase. Amsoil needs to figure this out , and quickly.
BTW Amsoil AMO (10w40 HI PERFORMANCE) does not meet VW 505.01. It meets vw 501.01 AND 505.00.
 
Well that settles it. I'm not buying a TDI PD if I have to use VW's overpriced oil just to keep the warranty intact.

I'll stick with my rotory pump TDI and my Amsoil 15w40 oil.

Don't loose all hope, yet. The dealership that I work for has already contacted our local Mobil supplier to obtain a less expensive alternative. I'm sure there are many other dealers who are doing the same. I understand where you're coming from. There's no way I'd want to spend $39.00 just for oil

@ every service interval on a $20k car. Give us time, we'll find something more reasonable.
 
I don't have a bottle of Delvac 1 5W40 to look at, but was curious if that oil listed any 505 specs?

Ted's spec listings sure look a lot like Delvac 1.
 
'Kule,

Mobil makes a special 5w-40 for the VW 505.01 application in Europe - it's not the same as Delvac 1 or their Delvac SHC oils....

Take a look at the viscometrics of this Castrol product - the viscosity @ -25C is only 3400 Cp, compared to 6000+ Cp for the US spec Delvac 1. These VW 505.01 oils generally have superior cold temp performance to the 5w-40, CI-4 rated, synlubes you find in the US.

I sent a sample of this Castrol oil out for a baseline analysis last week. I'm particularly interested to see if they are using any supplimental antiwear additives like Moly, Boron, etc.

Here's a list of VW-approved 505.01 oils (and others too). Not sure how many of them are actually available in the US...

VW Oils

I've posted it recently in the used oil analysis forum.
 
My 04 PD TDi manual says nothing about that special oil. the manual makes no reference to the PD engine but only the older 90Hp one. VW screwd up again. I can see some people buying the PD Tdi and using non approved oil, couple of yrs later the engine is damaged and VW pays for a new engine...unless they get something in the mail fast.
 
The 5w-40, Motul 6100? and dealer sourced, Castrol 5w-40 meet the VW 505.01 spec. at this time ...that's it, period. I posted a VOA on the Castrol oil before the holidays ...nothing special as far as the chemical signature.

Quite frankly, it's a very small market in N/A and the spec may change again in 1-2 years, so don't look for more than a few, homegrown VW 505.01 oils to ever be made. I know that Petro Canada is evaluating the situation and may decide to make one - probably based on their Duron 5w-40 basestock. From what I understand, the required additive chemistry is pretty standardized, so there is little room for innovation. The VW 505.01 lubes are basically high end, commodity products.
 
Actually, from what I've read, they don't want you to use a 5W-40 but the Castrol SLX LongLife II 0W-30.

In Europe, you can also use Mobil SHC Formula LD 0W-30. Has full approval for PD motors in VW/Porsche/Audi group.

I tried calling my commercial Mobil rep to ask if they carry the SHC Formula LD 0W-30. Too bad we don't have those "picture phones" we were promised 30 years ago.

I had to imagine that "deer in the headlights" look, which is no substitute for the real thing.
 
Also, VW has changed the spec for the PD. It is NOT a 505.x spec.

The proper spec for the new PD is 506.00 or 506.01. This is a VERY new VW spec. The viscosity specified is 0W-30, not 5W-40.

I can't find the manufacturer specs for Castrol SLX LongLife II, but the specs for Mobil SHC Formula LD 0w30 has me concerned.

The Pour Point is "only" -39 C, and although no MRV BPT is mentioned, it would probably only be -30 to -35 C. Last week I had -42 F!

Cripes, even Delvac 1's newest blend for CI to meet EGR requirements is good for better than that. Wonder if Amsoil HDD 5w30 would work? At least it's cold weather performance would be far superior to the SHC Formula LD.
 
The North American PD's don't have the flexible service schedules. An SAE 5w-40 is the required grade for these specific varients ....
