@bhgonz3 - let me be the first to welcome you here to the forums!

Questions for you:
  1. Is this your first diesel vehicle?
  2. What is you typical driving style?
    • City driving with lots of short trips?
    • Highway driving of long durations?
Rather than rehashing things again here in this thread, I suggest starting with reading thru this thread: "Normal" Scheduled Maintenance

Short answer: You can see as little as 2500 miles or over 10,000 miles between oil changes depending on a.) your driving style and to a lesser extent b.) the type of diesel fuel you are using (Hint: BioDiesel is better for our trucks)

Not a lot of us knew this before purchasing our F150 PS Diesel trucks, but you can read the evolution of how we arrived at this conclusion in this longer thread: Stuck in regen???

Again welcome aboard to the forums!

Also pretty sure that oil doesn't meet either of the required ford Specs. It must meet WSS-M2C214-B1 if using an API FA-4 oil, or WSS-M2C171-F1 if using an API CK-4 oil.

Sounds like time to change oil. Be sure to use approved diesel oil or end up like a guy I know who used non-diesel oil in his VW TDI and ruined the camshaft!

@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: START HERE: New FORScan user education

Any questions after reading up on these topics, ask back here or feel free to PM me...

FordPass gave me a notice that an oil change is due in 400 miles, this would put the mileage at 3,800. Is this a normal interval?

@chiefdave - pretty spot on with what I saw for my first FordPass OilMinder notification, based on my driving style.

Please read thru posts above for details on why you might not be seeing Ford's magical 10K oil change interval...

I bought my truck brand new with zero miles in 2019 but it arrived at the dealership in 2017. I drove it about 300 miles and it told me it needed an oil change. It has an algorithm that goes of date and life I guess. Ford paid for the oil change.

Yes, it has a timer, I'm sure of it. Mine was same way, no miles, sat on dealer lot, needed oil change.
