No 506.01 oil analysis as of yet?

++ Click here to view a spreadsheet with all PD UOAs, and newly added 505.01 & 506.01 UOAs ++

Motul 506.01 VOA



55749 = Motul 506.01 0w-30 UOA, Fuel: 40% winter D2, 60% B60
7495 = Castrol 505.01 5w-40 UOA, Fuel: 95% B100



There were a few factors that may have effected the wear metal comparison between this 506.01 UOA and my previous 505.01 UOA.

Factors that may have contributed to a wear metal increase were:
<ul type="square">[*] Percentage of BioDiesel use: 40% winter D2 / 60% B60 vs 95% B100[*] Italian Tune Ups: 6 to 8 runs where I firmly accelorated past 110mph vs I don't recall any 100+ runs during the previous OCI[/list]Factors that may have contributed to a wear metal decrease were: <ul type="square">[*] theoretically an oil that provides superior wear protection[*] engine is 5k further along the break-in process[*] much more highway driving, and extended 60mph highway driving en route to 1000 mile club (e.g. 1000+ miles / tank of fuel )[/list]Fuel Economy:<ul type="square">[*] 505.01 = 41.42mpg[*] 506.01 = 52.05mpg
506.01 definitely increased fuel economy in the neighborhood of 10+%, but the 25.6% increase indicated by these numbers is due to the much greater percentage of highway miles during the 506.01 OCI.[/list]An unexpected result is that even though the 506.01 sample was subjected to relatively dirty fuel (higher sulfur D2 as opposed to the less than 100ppm sulfur B100 for the 505.01), its Soot level is the lowest I've seen for a PD using just and OEM oil filter at 0.12%.

That's incredible! Is the 506.01 safe to use? Does it void the warranty?

IMO - Yes.

According to my dealer - No. Check with your service manager.

FWIW: someone reported that VoC said it's OK to use the 506.01 oil as long as you do not exceed 10k mile ODIs or 1 year --whichever comes first.

Someone asked VWoA about the 506.01 and they ....well....you know...they didn't know what it was.

Dorf, you have got to get some t-shirts made with those service pics on them. They are too freakin' funny! Come up with a witty caption and you could sell them. Proceeds to help out Fred's, of course.

Sunrg Since you are draining the Motul 506.01 with only 5k, can we assum you are not happy with the outcome? Will you be running the ELF 506.01 and testing?

I'm draining this oil tonight and filling with a 505.01 oil to continue the head-to-head testing of these two specs in the same vehicle.

From earlier posts:

* If the 5k 506.01 UOA does not look good I will drain and replace with 505.01.
** If the 10k 506.01 UOA looks better than the 5k 505.01 UOA, I will keep the 506.01 in until 15k.

<font color="red"> This changes everything! </font>

The spectrochemical re-analysis of the Motul 506.01 just came back and the three wear metal levels that were relatively high (when compared to other PD UOAs) are all LOW in the newly re-run spectrochemical analysis: <ul type="square">Cr = 1, Pb = 2, Sn = 0[/list]Even though I had qualified my original concerns (statistically/scientifically one UOA is nearly meaningless), this re-test on the same sample has 1) removed any 506.01 concerns that I may have had and 2) clearly demonstrated why we should not read too much into a single UOA.

To clarify, the re-tested sample analysis results are completely in-line with the 506.01 claims. Better fuel economy, excellent protection and improved performance with outstanding soot control.

I've updated, edited and removed my earlier posts that discussed the initial UOA result.

that's good news.

[scratching head]It makes me wonder why the initial results were off that much[/scratching head]

Just one last quick announcement...

We have a new oil entering our PD Oil Analsis study: <ul type="square">PENTOSYNTH Synthetic OIL 5W-40 (TS) SJ/CF[/list]

This oil can be purchased through the TDIclub's own Danix from the www.TDIparts.com website, at very competitve pricing.

MSDS - PENTOSYNTH Synthetic OIL 5W-40 (TS) SJ/CF

Look for VOA lab results shortly and at least two UOAs to follow.

The Pentosynth TS arrived today. It's nice to see the number of quality oil choices for PDs increase A sample for VOA will be sent to the lab tomorrow.
