The above webpage is a spreadsheet with all the PD oil analysis results we have to date.
Wow, the wear metals are much higher in the Motul UOA! Do we have any other Motul UOAs to see if that's just a fluke?

We need more Motul UOAs!

There are a few things that should be considered. This was the only Passat UOA - heavier vehicle and more horsepower & torque. or, tomo366's the high wear metals could be the karmic result of flaming newbies

seriously, if there's anyone using Motul that'd be willing to do some UOAs that's be awesome.

I'm still using the castrol (dealership fill), will be loading motul 505 in the next few days... if you can hold out for 10K i'll do one..i'll have 20K on the car by then.. just let me know if it's needed then...

skinz2k5TDI - that'd be great. any chance you'd be interested in sending in a sample of the Castrol you take out for comparison purposes? testing two oils in the same vehicle yields the most relevant comparison.

i have a case of Motul 505.01 that eventually i'll be using / testing in our TDIs - but not for at least another 20k.

i plan on keeping this thread alive for as long as we own our TDIs so sending in a Motul result in 10k would be great. the more data we collect the more meaningful this study becomes.

thanks!

I can test the castrol... sure.... what steps do i need to take?? I'll do the motul as well and post the results of both

basically an OA kit is just a small plastic container (~4oz), you fill it with used oil, complete a short form, put it inside another small container they send you and mail it to the lab. the results are available both online and they mail you a hard copy. i purchased an oil sample pump too (~$25) so i could do intermediate UOAs and my sampling technique is consistent.

i look forward to seeing your first lab results!

Glad you guys are concentrating on Castrol and Motul, because I'm running Elf Excellium DID in both my 05 TDI and my sister's 04 TDI. We'll be able to compare UOAs.

SUNRG, any idea when you'll get the Elf VOA results?

the Elf VOA samples were sent in last week so we'll definitely see the results this week.

that's great that your using the Elf cuz we need Elf UOAs too. Elf's Evolution CRV 0w-30 is going in my Golf next - but that's 9.5k down the road. I also have a case of Elf Excellium DID 5w-40 but we're about 13k away from it going in my wife's TDI. Eventually, we'll run the DID for three changes or 30k and be able to contribute some significant Elf 505.01 data too.

Hey SUNRG,
I found out from a supplier that the TBN for the ELF 5w-40 is 12.0. A guy named William from Mars-Automotive is sending me a spec sheet in the mail, don't know what info will be supplied but would be interesting to see what results you get and what they spec! And I to will be using Motul 505.01 shortly (if it ever gets here) and plan on sending out for analysis after 7500-10k miles which with my commute should be about 4 months, that's some time but it's the best I can do. Then on to ELF 5w-40 and test that also, my driving is 95% highway so results should be good considering!

Challenger,

We do have the Elf spec sheets, and it will be interesting to see if the Elf 505.01 VOA TBN comes in at 12. Personally I doubt it. Spec sheets from the 505.01 (identical oil) published in Danish, Swedish and Norwegian list its TBN as 9.6. I hope I'm wrong but if I had to bet, I'd put my money on 12.0 being a misprint. VOA results will be in this week!

Elf Data Sheets:
Elf Evolution CRV 506.01
Elf Exellium DID 505.01

Glad to have you join us in the OA study! Like I recommended to skinz2k5TDI, if you could send a sample to the lab of the oil you're taking out of your PD in a few days (to put the new Motul in) that'd be ideal. then you'll have a personal baseline / reference point with which to compare your Motul results. PM AndyH and he'll get you setup with OA kits.

wear metal numbers are expected to decline over time and then stabalize at relatively low levels. so even if a Castrol UOA from 10k does not look as good as an Elf UOA from 30k that doesn't prove one is better than the other.

i've broken the spreadsheet down into <10k, >10k and i will add >20k, >30k etc. so we can have as relevant a comparitive analysis as possible.

Default Re: PD Oil Analysis Thread

moments after making the above post i logged into the Oil Analyzers, Inc. website and the Elf VOAs were in:



Dan at Oil Analyzers noted that there are two different TBN tests:

TBN Test: ASTM D2896 [used by manufacturers]
TBN Test: ASTM D4739 [used in UOA, usually produces a TBN thatís about 2 points lower than D2896]

So the Elf 12 TBN was not necessarily inaccurate. 10.20 is still roughly 1.0 better than Castrol or Motul.

Of course the more important tests are UOAs. VOAs are just indications as to how well an oil <u>may</u> perform compared to others.

Drivers wanted.

i was just looking at these numbers and came up with this VOA comparison...
LAP (Lubricating Additive Package): the sum in PPM of an oil's Boron, Magnesium, Calcium, Phosphorus and Zinc content.

Here are the 505.01 and 506.01 oil LAPs:
<ul type="square">
Elf 506.01 = 6093
Motul 506.01 = 5628
Elf 505.01 = 5592
Castrol 505.01 = 5211
Motul 505.01 = 5049[/list]
