Latest UOA for my 2.0 CR Jetta TDI. Thoughts?

There is a lot of wear going on there, and there has been for a while now. I don't think a 10k change interval is appropriate for your driving style or habits -- the oil is falling out of grade and you've got heavy fuel contamination that isn't being burned off. Are you doing a lot of city driving?

I would say that my driving is 70% city, if you can call my area city, running Castrol LL03, no fuel additives, and B5 fuel. I am also a fairly heavy footed driver. Also, the high numbers on the last 2 UOAs is cause the car was brand new. They were run on samples at 10K miles and 20K miles

What is cheaper? An engine or a couple of extra oil changes a year. I would not go 10K.

I don't know squat, but I'd do what B-S suggests; if a 5K interval produces 1/4 the wear...

I'd try to establish whether the wear is linear, or geometric etc.

Your engine has only had 3 oil changes in 30K. Thats about 3-5 less OCIs than the average person. While your wear is high its due to the long OCIs and the engine breaking in. If you want to see if you can get lower wear, do a few short OCIs and then sample. That oil looks WEAK as well. What oil is specified for this engine? It looks like it needs to move up to M1 0w40 if that is an approved oil. I'm assuming this is a diesel engine?

Did coolant somehow get in the oil? The K+ is lower but was really high initially.

Saw that but the glycol test is 0. Wonder if that is a valid test for VW coolant.

Definitely the oil. If I'm sitting on a ticking time bomb though, I want to trade it in before [censored] hits the fan.

Will do a couple shorter OCIs and see what it does.

This is a 2011 VW Jetta TDI. I am running both the 10K mile oil changes specified by VW, as well as the Castrol SLX Pro LLO3 full synthetic 5W-30 that is both specified and factory.

I have had no coolant loss or leakage.

Actually, multiple UOAs have found that shorter intervals can actually increase wear in these VW TDIs

Don't believe anything VW says, I am not an engineer, but UOA results are tangible...Now having said that I had an 02 TDI, totally different animal, but I did their recommended OCIs and the results were poor. I shortened it up to 4500-5000 miles and wouldn't you know it never had a bad UOA again.

10K is just too long, go short this time and see where its at.

I'd probably trade it asap.

maybe a new VW if you prefer those.

Bingo -- what's great is seeing guys running non-507.00 products (GASP!!) and returning excellent UOA results.

"After replacing the worn cam at 53k miles, the car (PD DSG Jetta) had TDT for the first interval, and then has had T6 for the rest. No wear on the new cam after 80k miles."

10K OCI is too long, forget the owners manual, cut the interval in half and see how thing pan out. Just out of curiosity do you have an OLM? If so how long before it triggers an OCI?
