Oil Dilution + Strong Gas Smell + Soot on Tailpipe + Poor Mileage

[VG EDC]

I picked up my 2025 TRD ORP Hybrid late December of 2025. I chose to get the Hybrid for more power and some help with the mileage. From day one, it always felt like it was running lean, and the mileage was at least 50% worse than advertised. I chalked it up to a break-in and the cold; I didn't think much more of it.

Now has 4265km (2650 miles) on the clock. I noticed the other week that my Garage had a strong smell of raw gas. I checked the oil and found major oil dilution. My oil was 1.5 litres overfilled, smelled like gasoline, and was very thin. I took it to the Dealership. After testing all day, they couldn't find anything wrong and told me to change the oil and no corrections at this time. I dropped the oil and confirmed it was 1.5L overfilled. We changed the oil and filter. I then took it out for a 20-minute drive later that night and got it up to operating temperature. The oil level was already 1/8" over the top fill dot, and again smells like fuel. I also noticed thick soot on the tailpipe.

I'm concerned this will fry my gaskets/bearings.

Does anyone have any ideas as to what this could be from? High-Pressure Fuel Pump? Injectors? Bad Sensor?

I would do sea foam cleaning and then another oil change to try cleaning out the residual gas\crap from everything. Keep an eye on the oil levels for sure. Best case scenario was some idiot overfilled it before delivery?
