So you Pass the Bubble Test
That's Good
That means the Inject are Good
SO if you do have Fuel in Oil its likely from Injector Orings
You need to be 110% Positive though
If I was you I would Check the Oil Leval with the truck cold make a Mental Note where its at and then Drive a few weeks
If its putting Fuel in the oil you will see it rise on the dipstick over time
As far as it running worse with Fresh oil this is very Common
The deal is the 6.0L Shears its Oil so its A lot thinner when its got 5K Miles on it
Then you add fresh oil and its Like hONEY CONSISTENCY compared to the old oil and it is Harder for the injector Spool Valve to Shuttle Back-N-Forth threw

Your going to need a Gauge to trouble shoot them Engine sensors
DashBoss
ScanGaugeII
there is Torq APP not shure what this one Does
DTC INFO
P2262
Stuck turbo, MAP sensor, MAP hose plugged up; sensor unplugged, or leaking, CAC leaks, intake leaks, exhaust restriction, EBP sensor or EBP tube plugged. This code is set when MGP does not go above 5 kPa or 0.7 psi when the following conditions are met: rpm must be above 2800; VFDES above 20; and EGRVP is below 0.10. All of these conditions must be met for 5 seconds for the code to be set.

The P2262 is probably why it runs Bad and Not from bad inject
All 6.0L suffer from Fuel Delution of the Oil
So you must Investigate More then by Smell Alone
Keep a very close eye on the oil leval

Kinda High risk to Drive it
OverBoost can Lift the Heads off the Deck of engine
But I think your Not making enough Boost so you probably OK to drive it
That^^Said if you do drive it Drive it like an Old Lady or atleast keep Boost PSI Low as possible
would be worth checking into some gauges for it. One that goes to the OBDII Port
Could be wrong but I think your Problem is the P2262 DTC and Not Fuel delivery issue

are you sure its not an EGR related problem.
If you cant smell fuel anymore and have ruled out injectors, look into the EGR system too, rule out a possible EGR purge at idle or too much EGR actuation during light load. This will cause a miss as well.

It would of had to restrict air flow
A misaligned air filter would likely let unfiltered and Unmetered air into system
unmetered air can cause problems But once aligned and installed correctly truck should have ran Good Again

Your pretty well DEAD in the Water without Gauges on these trucks
we could go back-n-forth all day
But without Numbers only god knows whats up
A lot of Autozones have ScangaugeII in stock
or
www.scangauge.com
There are others but SGII is usually readily available at Auto Zone
