I would change it at 6 months and see what the results are.UOA done at 53000 kms on my CX-9. Possible coolant leak reported, I'll keep an eye on it and send in another sample at my next oil change.
Smellmsome? Big thumbs... sorry!
Uh ohh.. Well I guess at this point best you can do is keep a close eye on coolant levels, watch for white smoke from your exhaust... At least you're still under warranty.

There is a suspected internal coolant leak. No other symptoms of an external coolant leak.

This coolant leak issue on the 2.5T should be a concern for all 2.5T owners. It seems to be a potential problem after 3 ~ 5 years mostly caused by cracked cylinder block.Uh ohh..

Lol similar results but I switched to amsoil 5w-30 boosted from their signature. Why? It had a higher viscosity at the higher temperature testing point. I do 5k changes. Their boosted product is also cheaper than their signature product line. So win win.Sharing an experience with Rotella 5w-30 (multi-vehicle).
This oil turned out to be particularly good for engines with dilution. Got a hint from WRX forums and got repro on both of my cars. Rotella results marked with red:
1: 2015 WRX started to show diluted analysis after a Stage1 protune.
2: 2019 CX9 - dilution issue started from 5k miles, well described here ) To mitigate the issue I used to run very short intervals and was consistently getting low viscosity within 2200 miles. Now I can get back to 5k intervals or even longer. Amazing.View attachment 314330View attachment 314331
The Rotella 5w-30 is pricey, but exactly in November Nappa runs a special.
Oh that’s interesting on the fuel difference. Not gonna switch but I wonder why?the XL amsoil is also Api sp certified (vs signature which is not) so thats a win for warranty purposes as well. Very good oil indeed.
Btw the fuel dillution is more visible when driving with 87 fuel.
