Allgemeiner Nutzwert von PD-Öl statt 505.00? | Posts 16+

Thank you for the clarification...

Even if Manuel used a zero too many, I'm sure everyone here knows what he meant. You can safely assume that, even with that mistake, he knows what he's talking about.

Unfortunately, the core question still hasn't been answered.
What specifically differentiates PD oil from non-PD oil?

My "Amen" referred to Bertil's comment, which I fully agree with.
I am familiar with the operating fluid specifications for my engine, thank you.

Hi,

@Roger:
The oil suitable for positive displacement (PD) engines remains lubricating even under extremely high pressures, as can occur in PD engines.
Regarding the "zero too much" issue: I simply doubt that his manual states that his oil must meet both the 505.00 and 505.01 specifications. As far as I know, the only difference between 505.00 and 505.01 is the surface pressure.
If Manuel's engine requires oil with high shear stability, would it be sufficient if the instructions simply state: "Oil according to specification 505.01"?
If Manuel's engine needs oil that doesn't require high-pressure stability, the manual should state: "It must be filled with oil that meets the 505.00 specification." Alternatively, oil meeting the 505.01 specification can also be used, if you're willing to spend a little more.
I suspect that, in Manuel's case, it's a list of which standards he can meet. The manual then states: "Oil according to 505.00 and 505.01," where the "and" in normal language should be replaced with "or" so that even "mathematicians" can understand it .

Okay, and I wrote much more about the PD oil above.

The xxx01 oils perform better under the high surface pressures on the PD elements. Therefore, each engine requires the oil according to its specific standard.

Hello,
I once read that you should only use LL oil in engines specifically designed for it.
It was likely during the 'transition period' when the 'QG1' equipment was being introduced for PD engines.

It might be, but I wanted to answer this question from you:

@Günther: Are you saying that my statement is outdated? What does "LL-Öl" stand for in your last post? Longlife or Leicht-Lauf (light-running)?

Hello Micha,
I meant cross-country ski oil (for PD engines). Back then, some people believed that this oil was also particularly good for 'normal' engines.
Best regards,
Günther.

Hi,

Okay, so: At VW, "LL" stands for "Longlife". Also, all the VW Longlife oils I know are also low-viscosity oils, partly because of the reduced HTHS (High-Temperature High-Shear) value. (And also, due to the potential fuel savings, which I won't comment on.)

The "QG1" specification indicated that engines equipped with these engines could tolerate oils with a reduced HTHS (High-Temperature High-Shear) viscosity without experiencing immediate failure.
However, it still applies: Only use VW Longlife oil in engines that are explicitly approved for it.

Do not confuse these with regular oils that have the manufacturer's "Low Viscosity" designation. For example, there are 5W-40 "Low Viscosity" oils with VW 505.00 or 505.01 specifications (meaning oils that the manufacturer labels as "Low Viscosity," but which must be changed every 15,000 km in a VW diesel engine and do not have a reduced HTHS value). These oils are approved for use in VW diesels without the "QG1" additive code, but can of course also be used with the "QG1" additive code, provided the oil is changed every 15,000 km.
Okay, to summarize briefly:
If you already change your oil every 15,000 km, use long-life oil, and drive your engine hot, then a good 5W-40 oil that meets the VW 505.01 specification is the best choice.
If you change your oil every 15,000 km anyway, don't have any specific performance demands, and drive your engine hot, a good 5W-40 oil that meets VW 505.00 or 505.01 specifications is generally a good choice.
If you absolutely want to extend the maintenance intervals, use an oil that meets the VW 506.01 specification, preferably one from a reputable brand. However, keep in mind that this type of oil may not be particularly stable at high temperatures.
If you absolutely want to extend the maintenance intervals, use an oil that meets the VW 506.00 or 506.01 specification, even without using extended drain interval (EDI) oils. However, keep in mind that this type of oil may not be particularly stable at high temperatures.

If someone really wants to save fuel, they should focus on how they use the accelerator pedal, not on using the "right" type of oil.

Are all the imperfections removed?

Hi,

Since I'm not allowed to publish the specifications, I recommend checking out the website of a motorcycle enthusiast who provides a good overview on their page.
http://www.transalp.de/technik/pd-technik/verschiedenes/download/oel/KFZ_schmierstoffe.pdf
Here's the translation:

"This is not advertising material from oil companies (like the one you posted), but rather a factual compilation of the most important technical data for lubricants and their classification."
Everything else has already been written here and can stand as is without further contradiction. In this forum, any false statements are immediately challenged, otherwise they remain unaddressed. Therefore, your allusion to "Stammtischlatein" was completely inappropriate and was perceived as an insult.

Hi,

current status:

506 00: WIV, reduced HTHS viscosity, not approved for particulate filter diesel (PDE); due to the reduced HTHS viscosity, increased engine wear.
506 01: See 506 00, but with the additional requirement of PDE approval.

505 00: No WIV (Water Vapor Index), normal HTHS value of at least 3.5, not suitable for PDE (Polymer Dissolution Equipment).
505 01: See 505 00, but with the additional requirement of PDE approval.

new oil standard:

507 00: WIV, HTHS of at least 3.5, which provides significantly better wear protection than 506 00 and 506 01, lower ash content, therefore recommended for vehicles with DPF (Diesel Particulate Filter).
I'm not entirely sure which engines are approved for this oil specification yet. According to my workshop, all engines that are compatible with oil 506 00 or 506 01 are approved for oils meeting the 507 00 standard. However, I won't believe it until I have written confirmation from VW.

Perhaps someone who is closely connected to Volkswagen could provide more detailed information about which engines are approved to use oil that meets the VW 507 00 specification.

Few people are likely to be closer to the truth...

Yes, Manfred is very well-informed. However, it's a delicate balancing act for him, as VW has already challenged some of his information, and his website was therefore unavailable for a long time.
Although he's not directly involved in the development there, he really has excellent sources of information.

Just now, when I've already stocked up with 50601 for the next change, new standards are coming out.

Hmm, something still doesn't seem right.

I've seen similar standards listed on eBay by oil sellers, but Castrol, as the manufacturer, didn't seem to know anything about 'Longlife III.'

Also... in the future, the 50501 standard will also be permitted for PD engines, which is great news!

But they apparently go from 5W to 0W...

Hi,

Aber die gehen anscheinend auf 5W von 0W....

Well, the 1.5 seconds longer oil circulation time in the 5W doesn't make the engine any fatter. What's more important to me is that the HTHS value of the 507.00 is back above 3.5 mPa*s (i.e., in line with the ACEA A3/B3 specification). Let's see what the viscosity is at 100°C and what the viscosity index is. (If anyone can get me a datasheet for a 507.00 oil, please send it my way...)
@Roger: I would give the 506 01 to my neighbor if I had a problem with him, or I would sell it on some online marketplace.

And what would be new about that ?

Since it was only approved for diesel engines WITHOUT a PD (Pump Düse) system.

Hi,

@Ulf: Perhaps he means that 505 00 should also be approved for PDs. After all, according to one lubricant manufacturer, there is no data that allows an oil to be approved according to 505 01, but rather the "approval is determined in engine tests." Whatever that exactly means.
It's about time that oils meeting the 507 00 standard are available everywhere.
