I had the same fuel dilution on E50 as I did on pump gas.

2018 GSW St1+ tuned w/K&N. Second change with LM at ~7.5K OCI. Seems all good and interesting comment for the K&N haters.

I finally got around to dropping off this spring's sample last week and got the results this morning:


I couldn't be any happier with those numbers. I run the full 15,000km change intervals (though I do plan to extend it after the warranty is up) and make sure to hit the rev limiter at least once every single day.

All these threads prove is that 10,000mi intervals on good oil is entirely doable, and that the 5k (on stock tune) crowd is under voodoo.

My 2 UOAs were from wintertime 4500 miles. a Tiguan 6M with APR, same engine as GTI EA 888 Gen 2.



Started with thin API 30 weights of 10cSt, Mobil 1 0w-30 SL and Edge 5w-30, which dipped down to a 20 weight, but wear levels were very low.

CAT Labs are very cheap and you can drop off your sample at any dealership. Like $15 iirc.

Some oils when you do a VOA, have presence of silicon in it, which is from a defoaming additive.
You mean silicone.

Sand, in the form of silicon, can be residual from the casting process.

Or from run of the mill "dirt" coming from through the filter.

You have dirt entering your engine and causing excess wear. Get rid of the clown air filter.

Silicone is the defoaming additive, not silicon.
