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

Also, keep in mind that it's a different engine! 2.0L TDI vs 1.9L. So some differences in wear metals would definitely be expected.

Slight change of plans for me my Motul supplier said it was on back order and since I am doing my oil change SAT. the 22nd I had ELF Excellium DID 5w-40 overnighted to do the change. So in a couple of months I will have a UOA of ELF 505.01. I am planning on doing a UOA at 5k and 10k. I will post the results when I get them for the Castrol that's in there now and the ELF that's going in!!

Lubro-Moly's Diesel High Tech 5w-40 505.01 is available in Cananda:
604-232-3396
http://www.hopefungautoparts.com/LubroMoly.htm

LubroMoly also has a Synthoil Longtime Plus 0w-30 506.01

I spoke with the importer for Lubro-Moly in California 562-597-5519. The following is my attempt to accurately report what he (I didn't get his name) said:

He said he's "confident the Lubro-Moly 505.01 oil is superior to the Castrol, Motul and Elf" and added "there's no comparison between the Lubro-Moly additive package their competitors".

He predicted that we would not find a significant difference between any of the 505.01 oils in UOAs. He said we would notice an immediate difference in the way the vehicle sounds using Lubro-Moly but that other benefits would not be recognized in the short term.

If you have further questions I recommend giving the guy a call or visiting the Liqui-Moly website.

I have enough 505.01 and 506.01 to test in our TDIs for the next two years - but if anyone is interested in trying the Lubro-Moly, testing it and posting the results that'd be great.

Wow!
I am a newbie here. Surely, you guys know about engine lubricants !!! I've learned so much about oils by reading the forum. While I was doing some research last night, I came cross this web, http://www.turbofrogperformance.com They are authorized MOTUL and ELF dealer. They don't usually stock Motul 505.01, 506.01, and Elf Excellium DID 5w-40. However, they replied back to me that they would have them if there is enough demand.
Now I am hooked. Thanks, TDI Club! I can't stop reading about engine lubricants

SUNRG: I just sent a Motul sample in. 33k + change on the engine, bang on 8k on the oil. Will advise when it is in.
Cheers

Great! Mike_04GolfTDI just sent in some Motul for 10k analysis too.

is adding TBN an option with your lab? i ask because your engine is still relatively new, which means wear metals should continue to steadily decrease, and since you've switched oils Castrol to Motul, if wear metals drop it's possibly unrelated to the Castrol to Motul switch. if your wear metals unexpectedly climb, that would not bode well for the Motul.

however, TBN is one of the values that <u>are</u> telling even in young engines.

i think challenger and skins2k5tdi may have recently sent samples to the labs too - so we may have a good bit of new data to enjoy in the next couple weeks.

cheers!

TBN is an option, didn't do it.

Here it is... oil sample # 4: http://pics.tdiclub.com/data/500/132...35028-0264.PDF

This is Motul 505.01 - ran it for 8000km bang on, car has 33,410kms. It is the first time Motul was used, the previous three samples are Castrol 505.01. Refilled w. Motul 505.01 again.

Didn't get a good look at it yet, but wazzap with the copper? Will need to get them some fresh oil as well, I guess it was their first time analyzing this stuff.

Spicy,
Some additive packages will leach copper from plumbing. This will be below a micron and won't cause damage even in high concentrations. There's no other sign of wear, so not a 'wear metal' problem.

The spectrum for ester base oil is very similar to water. Labs not used to synthetics, or some synthetic formulas, will have trouble with the infrared analysis. They should be able to calibrate with a VOA and should re-run your test for free.

Here are my oil analysis results. Oil is Motul 505.01 with 16,000km on it. Vehicle mileage is 31,387km.

this is a good UOA. wear metals look fine. i bet the iron will be under 40ppm on your next 10k interval.

a great number is the V @ 100C. the Motul 505.01 VOA was 13.55, your oil viscosity after 10k was still 13.5, that's excellent.

mike and spicy, maybe it'd be worthwhile to consider Oil Analyzers, Inc.. for around $15 USD, you get all the info you're currently getting plus TBN and no infared problems...

thanks for posting this data. i'll add both of your UOAs when I return to VA next week.

cheers!

spicy - you're oil looks great. i personally think you should go to 16000 kilometer intervals. IMO the oil is too good after 8k (km) to pull it out and recycle. mike's motul still looked good after 16k. and, since both of your engine's are still young, the UOAs are only going to get better.

however, i'd be more confident making this recommendation with TBN and infared data.

cheers!

I'd like to stick with Finning because I live close to one of their dealerships and it's very convenient for me.

Next time I do this I'm going to provide them with a sample of new oil so they can do the infrared analysis. (as they suggest) The annoying thing is I asked the guy at the parts counter where I bought the kit if I should provide a sample of new oil and he didn't think so. Otherwise I would have. I have to remember to trust my instincts as they have served me well over the years!

I almost want to drive more so I can get to my next oil change quicker and do this again!

Me too... just guess why (I have referred to Finning MANY a time on these forums... cough, cough, wink, wink)

I'll get them a virgin sample, don't worry about it.

For those questioning high copper content, a sample of your unused oil is really necessary for the lab to see if copper has grown...reason being refiners (read oil mixers) often use a big hit of copper to "quiet" the clanging in diesels. If Motul used a considerably high copper additive as compared to Castrol, the copper content would necessarily be higher. Unless you can get one of those guys to tell you what additive package they're using, you need to send a sample of unused oil.
BTW, all these guys buy additives from about three major suppliers and design their own additive packages to meet whatever requirements they like, and I'm pretty sure the Castrol synthetic is a hydrocracked oil with strong additive package rather than a true synthetic.
