Well it looks as if my issues with the truck are not 100% solved. In about 550 miles the truck has regened 4 times. It's taking about 30-34 miles to let it complete the regen process. It seems as though the average time between them is 120-150 miles. Sometimes a lot less than that.
The majority of these miles were highway miles. The biggest issue is the amount of oil I am gaining on my dipstick. As of now I am well over an inch above the max oil level when inserting the dip stick fully. When using the method where you don't insert the dip stick fully, I am approximately 1/4-3/8" above the max oil level. This is after only 550 miles!
I get that it will gain some oil over an oil change , but I am only 550 miles into having the truck back and I've gained this much. I can only imagine what it would be if I let it go 5,000 or even 7,500 miles between oil changes.

Any chance you can try different brand of fuel? From what I've read, frequent regens and excessive oil dilution are symptoms of biodiesel. Low cetane is another problem. I once used some Valero to save a few cents/gallon and regretted it with a bunch of regens on that tank.

We do use a Cetane improver that was recommended by Ford. As for trying a different brand of fuel, around here it all comes from the same place. The only difference between brands is the name and the bio percentage. 2% is the lowest you can get in PA. Looks like I'll be contacting the dealer next week.

Absolutely, however given the history of the DPF apparently soaking in diesel after not getting "light off" in regen, I'm inclined to think it will take a while of normal regens for it to actually recover.
As for fuel dilution, on my truck I have found I only get any notable fuel dilution (over 0.5%) if I interrupt regens. As long as I pay attention to when the turck is in regen (Scangauge II) and drive around until it completes I don't have a fuel dilution issue.
If you change the oil, ensuring it's at the proper level, drive a month or two making sure you don't interrupt any regens and you still have fuel dilution issues then I'd insist on injector inspection.

Sorry for not updating earlier. This was mainly due to there not being much to update on. The truck still regens every 150 miles and the dip stick keeps growing with oil. The dealer said this is normal and the truck will gain oil to some extent. So basically we will wait for the oil change to see how much oil it has gained. I do not know the correlation between how high over full equals x quarts of oil. We cut the oil change back to 5000 miles instead of 7500. I guess we will just wait and see.
In the mean time we are checking into aftermarket solutions for getting the emissions stuff off the truck all together. The warranty is up this year and hopefully as soon as it's done we will throw something on it. I am leaning towards the spartan kit now, but am looking into having the filter gutted and reprogrammed. This gives it a stock appearance but gets rid of the emissions, I am also told this is cheaper than the spartan kit too.
I will update when the oil change rolls around and let you guys know where I'm at.
Thanks again for the help.
