Well just got my Oil report back and it is showing fuel in my Oil 2.5. I did just get back from a long trip 4300 miles to SD and back. towing my trailer, I ave11.5. Blackstone said to wait and see what the next Oil test shows. Any thought what it could be. Thanks

Most generally that ends up being a faulty injector.

How can you tell if it going bad, Beside fuel in the oil, ? noise or just ODC.

If you have a misfire or rough running, thats the easy way to diagnose (look for the misfire, theres the source of the leak). But unfortunately, thats not a guaranteed method. When the 03 had all their troubles, I was putting dye in the secondary fuel filter housing, commanding the fuel pump to run, and with the valve covers off, using a blacklight to see where the dyed fuel was coming from. Sounds like yours is a slight leak, so, its not going to be easy to locate.

Depends....

1) Vince (Blacksnapon) could be right... injectors.

2) Could also be the way you sampled your oil?
a) Did you start up your motor just before draining (in or out of garage)?

b) Did you change your oil after driving for a while and then drain in your driveway?

c) Did you drive a short distance that same day and maybe did not burn off the moisture or fuel in your oil?

d) Maybe take another sample and send in for analysis (Blackstone could have made a mistake)?


Basically, a quick 1 minute start in or out of your driveway will create a false positive.

Well today I check for codes, No codes found, I used to get a P401 for the disconnected Egr, But I have pulled out the throttle body which was wired,
so the truck may be in default mode. I'll wait and see on the next oil report.
