Reading oil test results

[2ManyToys]

As I thought, I've got a leaky fuel injector(s). My oil report came back showing 2.0 Fuel Dillution, and 11.0 for Viscosity. The tech at Shell says that shows a malfunctioning injector dumping extra fuel causing the lower viscosity by dillution. Okay I got that, but can anyone explain what the numbers actually mean?
The truck is scheduled for Monday morning for a "Buzz" test to determine which injector(s) is bad. Not bad for a NEW truck with just over 3k.

2% fuel isnt REAL high but a viscosity of 11 !?! that like water !
what are the other numbers....whats the oil flash point ?

where'd you get these oil tests done at ? and what are the other numbers.

a BUZZ test wont show a leaking injector necessarily....a buzz test
is to see if an injector even turns ON...

on edit: blackstone says they dont worry about fuel in oil til its over 2%
and the 6.0L sheers the oil....the acceptable range for viscosity is 69-82
at 210*F

ford will tell you that as much as 5% is acceptable (but thats a repair
avoidance tactic)

im curious have you been idling the truck alot ?

and (most of this should apply to the 6.0 as well):

The Injector "Buzz" Test can be used to look for a faulty fuel injector. It is best to run this test on a totally cold engine, one that has sat overnight and has not been started.
Initiate the "Buzz" test and then listen carefully to the injectors as the test is completed. First, all 8 injectors will "Buzz" at the same time. Then, the IDM will "Buzz" the injectors in numerical order (1, 2, 3, 4, 5, 6, 7, 8). Remember that cylinders 1-3-5-7 are on the passenger side and 2-4-6-8 are on the drivers side, with cylinders 1 & 2 being at the front of the engine. You should hear a strong "Buzz" bouncing from side to side for all 8 injectors. If one of the injectors doesn't "Buzz", you've found a problem cylinder. It is important to note that when an injector fails to "Buzz" properly, you will still hear the other 7 injectors make a faint buzz...this is a designed function to protect the IDM.

Note: Because the IDM will "buzz" the other 7 injectors faintly during individual cylinder tests, it is possible for the "Buzz" test to report no problems detected. If the "Buzz" test reports no failures, but you don't hear a particular cylinder "Buzz"...more than likely there is a problem with that injector.

It should also be noted that an injector failing a "Buzz" test can have many causes. The injector can be in a failed state (loose armature plate screw, bad solenoid, etc.), the UCV (under valve cover) gasket or harness could be damaged or disconnected, the main engine harness could be damaged or the IDM could be damaged. Further inspection will be necessary to determine the actual problem...but at least you now have a place to start.
