This has me stumped!

Changed oil in the truck 2 weeks ago. noticed the drain pan was exceptionally full when it was all drained.
Decided i best measure it and see how much there was. 19 quarts! Oil doesn't smell like fuel (or in my case vegi oil) it smells just like any used motor oil.
So, thinking back to the time before when i changed oil i remember i filled it and didn't check the dipstick to be sure i had the right amount in there. So i decided it is possible i over filled it by an even gallon last time i changed it. Hmm...surely i didn't do a bone headed thing like that but at this point i hope thats the reason i have extra fluid in the case.
So i go ahead with my oil change and i make sure i got 15 guarts in it this time. Dipstick reads right on the mark. I drive it about 800 miles and check it again. DAMIT, its a little high on the stick...maybe 1/4" up. So i take it into Ford and have my diesel guy do a dye test on the injectors and i am sure i have one or two leaking. First of all he tells me he drained 15.5 quarts of oil out before doing the test. So i am sure i have a slow leak (.5 quarts in 800 miles = slow leak).
He calls back and says its all back together and there was no sign of leaking injectors.
So my truck just made an extra .5 quarts of oil this last 800 miles? And i put an extra gallon in the last time i changed it?
So for the techs, my questions is, if an injector were leaking maybe just very slightly, is it possible the dye test might miss it?
Now to add to this complicated mess, when i checked the oil, the plastic handle came off the stick, i slid it back on there but now i'm thinking if i didn't get the handle back on in the original position, the length of my dipstick may be different than it was thus, not accurate anymore.

Your truck is magic. Maybe if we figure out how it is magically producing oil, we can solve the world's problems.

leak

you cant run a dye test on injectors. Dye is for external leaks only. Run your truck atleast 1500 to 2000 miles then check. Oh, and the dipsticks suck on 6.0s.

Umm, i aint sure what your talking about there...we are talking about external injector leakage and running dye through the fuel while having the valve covers removed to look for the dye leaking into the valve cover area with a black light.
Its a standard Ford diagnosis procedure and he did it before when i had leaking injectors.
Why am i telling you this, your a Ford tech?

Your serious?
Theres a weephole in the injector and when the inner seal breaks down maybe from low fuel pressure or whatever caused it, the fuel will leak out that weep hole and into the valve cover area. No oil up there cause i think the first step is to pressure the die through the injectors for 10 minuts and then drain the oil and black light the oil. If you see dye, you can check each bank seperately by blocking off one side and then pressure the dye through the fuel bowl again for 10 minutes (motor not running), valve cover off, and then look at each injector with a blacklight and if its leaking externaly, you'll see it. Last time he showed me and you could definately see the dye comming from the injector.
I'll ask him what the tsb # is on this.
Don't mean to be telling you your business, i thought all ford dealers used that test.

clay in my opinion you have to have a fuel system leak, into the oil system to be adding oil,the dye in the fuel system would probably work , im wondering if the fact that your veggie oil may not smell like diesel fuel is why it doesnt have a smell to it , there is no other way for the oil to be increasing in quantity unless getting in thru the fuel system, as far as that test being standard ford procedure , i wouldnt say its standard but a legitimate way to find your problem yes
