Curious if anyone else has performed UOA's on the 2019+ V6 engines and would care to share their results or input.

I've been doing so on our 2021 Macan S (EA839) purchased from new and while the results have been mostly good but we are seeing higher than normal fuel dilution which is only manifesting itself in the analysis as the engine runs perfectly fine with zero signs of any issue.

Unsure if this is somehow inherent to the EA839 engine or the C20 Mobil 1 0w20....

Thank you!

I have used Blackstone Labs on other Porsches. I try to do it every other oil change. 2022 Macan too new for it yet but will do so. Probably worth waiting until 15-20K for things to wear in before getting baseline numbers. I am doing oil changes every 5K (5K done by me, 10K by dealer b/c it's free for the first 4).

I have a 2022 Macan GTS with a 2.9 liter V6. I purchased it new and now has 8,000 miles. The first oil change was this week and I have submitted a sample to Blackstone Labs for analysis. I believe this is a different engine than what you have but I will share the results as soon as I get them.

The Audi 2.9 and 3.0 engines are the basically the same engine (EA839) except for the crankshaft, which gives a slightly shorter stroke, resulting in a slightly lower compression ratio.
The 2.9 crank main bearings are slightly larger.
The 2.9 connecting rods and pistons are different.
The 2.9 has two turbos instead of one.

For oil analysis, they are comparable.
