2019 L2501 engine fuel system issues after engine warms up?

This is screaming fuel compromise / contamination.
Open the fuel cap and give a good sniff, do you smell gasoline?
I would drain all the fuel, clean the separator and replace the filter.
Add stanadyne to the fuel tank then add fuel.
You will need to run it for a bit, as the fuel injection pump holds some fuel.

Thanks. I still have the old oil. Unfortunately, changing the oil didn't help. I even underfilled it a tad. Still the same issue. Runs fine until it gets hot then starts burning oil from crankcase i'm assuming. Next steps? Do leak down tests on the cylinders? I'm really wanting to try to avoid taking it to the dealer lol.

any resolution to this issue ?
