You could try a 5w-40, MB 229.51 oil. The Mobil 1/ESP 5w-40 has the same level of ash (0.6%), as what you're using and is a bit thicker. So listers are already using it and it works fine too.

I'm not a fan of mixing oils with different additive chemistries.

Default Latest UOA 2101 Jetta

Here is my latest UOA from Blackstone labs. I shortened this run down to 6934 miles due to the results from my previous UAO. It seems better, and it may have been the collection methods used (dealer). I changed the oil this time to ensure a correct sample was obtained. I changed the oil to Amsoil 5W30 Euro this time, and plan to run it 10K miles and then sample to see how it compares to the Castrol SLX LL03. Please feel free to comment and offer opinions.

Vwthing,

This does look better, despite what the "experts" will tell you about shorter service intervals generating higher wear rates. But I digress....

You can generally go down to a TBN of approx 1.5 on these VW 507.00 oils without an issue of corrosive/chemical wear. Nothing really stands out here except the trace of fuel and the corresponding marginally low FP.

The specs on the Amsoil 5w-30 Euro oil are very good. I'll be interested to see how it works under these driving conditions.

Default 2nd Oil Analysis

Welp here is my 2nd oil analysis since owning the car. Its a 2000 1.9 ALH, with around 200k on the motor. THe oil is Pension Perf. II 5w-40. It seems this oil works well, but I am tired of ordering it from online at a premium so I have switched to t6 and will see how that compares next oil change.
I really don't know what to make of the Lead. That's bearings right? Anything I can do or should I be worried? Any help is appreciated

'Stream,

Your flashpoints are excellent. I'm guessing you do lots of high speed driving. With 200k on the motor your bearing clearances have naturally increased a bit, which will decrease oil pressure and result in marginally higher bearing wear. These tests don't show a TBN, but with only 7500 miles on the samples I doubt that's an issue.

A thicker, API/CJ-4 spec oil like the Rotella T6 should reduce the Pb levels a bit. All your other wear metal concentrations are fine; soot and silicon are fine as well. This engine is in very good shape internally....

Thanks TooSlick!

That will be interesting to see how the T6 affects it, I hope you are right. And I actually do at least half of my driving pure city. I have been thinking about getting new injector nozzles, but since there is no fuel in the oil and everything else looks fine I may wait.

Again thanks for the help.

Stream,

You should have no problem going to a 10k service interval with any API/CJ-4 spec, synthetic oil. A thicker oil will improve the ring seal, so your soot levels (total solids), may actually go down a bit. These are much better oils than the old VW 505.00 oil that was originally recommended for your engine variant.

This is all true, but on the flip side (devil's advocate), 502.00/505.00 allowed for hundreds of thousands of issue-free miles from TDIs and gassers (even the 1.8T), and continue to.

I saw just one on BITOG but it was with 27'000 km on it factory fill.
That was me....I just had another change done after 15,000 km and will send it in for testing.

Bob,

Before the introduction of 15 ppm, ULSD fuel, the VW 505.00 oils were very marginal for running 10k service intervals. Go back and look at the oil analysis data from the 1999-2005 time frame. This was particularly true for engines that were modified, ie chip tuned, larger injectors, bigger turbos or some combination of all three. It was not uncommon for these modded TDI engines to show 2%-4% soot concentrations after 10k miles. This is when it became popular to use the original Mobil Delvac 1, the Amsoil 10w-40, the Petro-Canada Duron and finally the Rotella T6 when it came on the market. (These were API/CG-4 and later CH-4 rated oils).

How does the UOA indicate soot load? Is this the insolubles number?
