Thank you for welcoming me to the forum. this is my 2nd diesel car, the first one is Q7 diesel. I'm driving short distance it is around 2 miles away from my house going to work.
@bhgonz - your very short oil change interval is most likely based on your extremely short commutes/drive cycles = with 2 mile drives, your truck never gets up to operating conditions where Active Regens can occur and if it does, you are not driving it long enough to completely clear out your DPF (Diesel Particulate Filter)
The
Stuck in regen??? thread documents chronologically how we determined that short drive cycles lead to what I have coined the "DPF Death Spiral" condition due to Ford not exposing DPF % Full in your IPC (Instrument Panel Cluster) and your never getting a full cleaning of your DPF (Diesel Particulate Filter) due to aborted regen cycles = once your truck enters Active Regen, you must drive for 15-20 minutes uninterrupted to thoroughly "clean" your DPF back down to 0% Full. The problem lies in you, as an owner, don't know how full your DPF is or when you are in an Active Regen cycle...
I strongly recommend that you purchase an OBDii adapter + FORScan software to enable DPF % Full, so you can determine when your truck is in Active Regen:
