I got my first oil change on a 2017 Civic Hatch EX (1.5L turbo) around 7000 miles. A bit early I know, but I was getting ready to go on a long trip and figured it wouldn't hurt. Anyhoo I decided to try Blackstone Labs for oil analysis and see if my oil life monitor was reporting accurately (it was also showing 20% left at the time).

When the results came back, everything was good, except possibly one number. From the report text:

"GRAHAM: This engine is new, so the excess metal and silicon is just the result of new parts wearing in and
harmless sealers used during assembly. It'll take a few oil changes before things start looking more like
universal averages, so just stay tuned for progress along the way. Those averages show typical wear after
about 6,300 miles of oil use. The 3.3% fuel is worth watching. We don't normally see this much fuel in a
wear-in type sample, but it's too early call it a problem. The fuel did thin the viscosity a bit. Check back in
7,000 miles again for another look."

The report says they usually see less than 2% in 'healthy' samples. So I'm wondering, it this a normal thing due to the type of engine in this car? Is it something to actually be worried about, assuming it sticks around? Or is it more likely the testing was off? It will be a while before my next oil change, but if anyone else has seen something like this I would be curious. If that number is actually a foreshadowing of repairs to come, I'd like to harass the dealer while I have a warranty.

Any thoughts or theories are appreciated!

Fuel dilution seems to be the norm with this engine, unfortunately.
There is a thread about it on another forum about the issue. Some are reporting over 5%.
Are doing a lot of idling?

This is just an inherent side effect of GDI. Things are getting better but the OEM's have not totally figured it out yet. Installing an OCC early on is a safe bet. I have spent years playing with GDI before in other various platforms especially Mazda's and they all do it. But still young engine so no need to be to concerned.
