The Mystery of 7L of oil

[Lenzbian07]

Hey lads and lasses, I’ve got a 07 1500 with a Hemi. Just clocked the odometer at 375xxxkm! My most recent fox was the oil pressure sensor, lock me out of ignition until I switched it out. Went to check the oil before swapping the sensor, and goodness me… my old girl burned through 7L of oil in 5500km!! Does anybody have any ideas as to where this oil might be going?
Exhaust is not blue, Nor does it smell like it’s burning oil. No signs of leaking anywhere around the engine bay or transmission. I haven’t yet checked the spark plugs, so I’m thinking this is an internal leak but it exceeds my knowledge and problem solving ability.
What do you guys think?

Wow that's almost 7 quarts of oil. Have you done a close inspection underneath and not just around the top looking down? I suspect it's burning it off without you realizing. That's 230xxx miles so it's high mileage.

Did you personally change the oil last? Curious what brand it was.

What do your spark plugs, and compression look like, you don't have an oil cooler and are you sure the right amount of oil was put in last oil change, you may have to do a leak down test.

Capacity is only (7 qts) 6.6 liters? 7 liters would be more than bone dry. How did you figure 7 liters? It won't show on the stick at more than 3-4 qts.
