Possible Fuel Leak?

Possible Fuel Leak?
Hello everyone!
It seems that my 2010 XK might have a fuel leak and I can't find the actual leak or cause. NO fuel spillage can be detected via visual or smell yet the fuel level display and range ticks down at a WAY faster than normal pace. I will lose about 6 extra miles on a 12 mile trip. Has anyone heard of any weak links or common issues with this year/model regarding this type of issue?
Appreciate any help as I haven't been able to find any information online so far.
Thanks!
Brian

Hopefully I have answers to all of your questions and I REALLY appreciate the help!!
My tail pipes do indeed have some black on them. I will try to attach a picture to this post.
Idle is normal and smooth. Coolant temp per Torque Pro via OBD is 188 degrees. No codes and I tend not to use the same brand or gas station when I fill up but I always use premium.
I’m not sure how to check for closed loop and I’m not sure what the proper fuel trim settings should be. I will post the test results below as well as the fuel trim results.

Should have a status value for closed/open loop etc. If OL it'll be bad mpg as it dare not do other than run rich.
Ignore MID/TID.
Trims, parked, hot engine, at idle & again at about 2500rpm.
You could out of curiosity also get a passenger to look when driving (or record data, if it will).
It's worth doing brim-to-brim fuel fills & hand calculate mpg as a sanity check.
