I found this UOA by accident on the Audi forum. I'm pretty sure it's posted somewhere on this site. What caught my eye was the lower additive levels. This is HPL Euro 0w30 502/504. I didn't know HPL made an add pack that has a relatively lower SA. This is a good option for those that don't want high SAPS. Still PAO/AN/Ester.
HPL Euro 0w-30 - VW 504
- Thread starter buster
- Start date
Suspect, But I’m not an expert.
I was wondering that too. Here is the final UOA. He also messaged Dave about it so I'm thinking it may be the correct oil?
The strong TBN retention is indicative of HPL. Additive levels not so much but it is a 504 oil so....
How can it be 502/504?

Bcs. VW504.00 is backward compatible. So I guess it is recommended for 502.00.
I agree it is suitable, but they are different approval requirements. I don’t like it when blenders do this.
Something’s amiss somewhere (or the sample-taker got really sloppy) for insolubles to go from 0.1 to 1.5 in 3k miles. The low-moly, high boron signature is what HPL’s “true” Euro oils are known for…I was wondering that too. Here is the final UOA.

"For full disclosure, during this OCI I did the following to help mitigate oil burning issues:
- ran two cans of BG44k in the gas within the first 1000 miles
- ran 32oz of Yamalube ring free after about 4500 miles
- added 1/2qt of HPL 0w-30 when the car told me to add oil right at the time I pulled the first sample ~4200 miles. After adding that half quart, the MMI showed no movement downward.
- changed oil filter at 4200 miles sampling from Mahle to a WIX filter.
- at 7000 miles I took an oil sample to send off THEN added two cans of BG109, ran for 20 minutes at 1500RPM then drained. Also changed the plugs and coils to APR. Scoped cylinders which were surprisingly clean.
The wear numbers look excellent imho on the analysis, however what is curious/concerning are the insolubles. In a little less than 3000 miles they’re up from .1 to 1.5!! WTH happened? I’m guessing it either had something to do with the yamalube, the WIX filter was garbage, or a ton of carbon broke free in that short timespan and didn’t get held in suspension. If anyone has any input I’d appreciate it."
Not sure if serious
No to the approval question
Only a suspect noncompliance if a semi metallic additive looks out of range of said specification
No this isn't about approvals. I've never seen a UOA/VOA of their Euro 0w30. Has a low SA level than most HPL oils, which is why I thought it was interesting.
Here's my UOA on HPL 5w30 C3
I finally got around to send in the UOA on this. A link to the interesting bits I found in my oil filter used for this OCI can be found HERE. Clift notes is that I found some material in the filter. The engine had been fed a constant diet of BMW LL01FE up to this point.
Tin (Bearings?) came in at 2ppm. Viscosity @ 100C came in at 10.8 vs 12.08 per PDS I presume if I kept going it would thicken up a little as I reached 10k miles. Going to do another UOA (LM 5w40) this summer (1 yr mark). I've only put 2k miles on the car since then.

Thanks, so this looks pretty similar. Good results. Oxidation is very low though. I wonder if this doesn't have the AN/ester cobase. My guess is the ANs and ester ratio is different in this grade hence different oxidation value.Here's my UOA on HPL 5w30 C3

there are some oils that have both approvals from same company.we discussed that long time ago and you claimed that it was a print mistake ,but it is isnt ..i think the one we had that conversation about was a motul one .
That's easy to check. Go look at the VW approved oil list and see if any have both approvals.

HPL doesn’t have approvals. They just recommend oils for applications.
be my guest , i am not interested.
