2004 Audi Allroad 2.7T 6MT Stg1 Mobil1 0W/40, 11,000/234,404

My first time doing an oil analysis. I use the "OEM" Mann filters and usually run the oil to ~15Kmi with a 7Kmi oil filter change (and oil top up). For life reasons this time I ended up running to 11Kmi on the same oil and filter.
1/3 city driving, 2/3 highway driving, typical commute length is 45min per trip. Since it's Stg1 tuned I like to stomp on it every now and then...

Right on the money …
And that retires the side !

Excellent report, and the flashpoint points to almost zero fuel dilution, which is great!

Given the results, is it worth continuing to change the filter at 7K with top-up, or just do the full oil and filter at 15K?

I think you could safely leave the filter.

+1. Filters get better with age, as long as the engine is clean to start with.

That's a fantastic UOA. You should be proud.

that makes no sense.

Should have pulled a TBN/TAN. I'm not sure how these engines are on oil but 15k seems like a stretch.


You might have the most reliable Allroad ever made.

I think what was meant is that as a filter becomes more loaded with contaminants it begins to filter more.

Yeah that's what he was trying to say but that doesn't make it true.

Oil filters do not get more efficient as they load up.

Nice UOA report OP.

I have a 2003 Audi Allroad 2.7 with 290,000 miles. Audi's 2.7L turbo engine has a longstanding issue with burning oil and, as they age, leaking oil. Mine does a lot of both but still runs and drives incredibly well all things considered.
