Ford diesel guys -- anyone dealt with frequent regens?

I have a 2010 F350 6.4L with 100,000 miles that I only use to pull my 16,000lb fifth wheel here in the mountains of Colorado (i.e. my truck works hard). Things were great for the first couple years, but ever since this spring I'm getting regens every 50 miles or so (used to be every ~150 miles).

My truck is all stock, and the only thing I did before this towing season started was an oil change and fuel filter change (I do them at 5000 miles and 10000 miles respectively). This time around I did use a different oil than the MotorCraft I usually use. I think it was Rotella, but could have been some other name-brand.

Anyway, my local diesel shop doesn't see any issues. They say the sensors all read normal, no codes, etc. I'm actually thinking one or more sensors actually ARE bad, even if they're showing in spec on the IDS. I know that can happen with the DPF pressure sensor.

I'm also wondering if somehow the oil I used is more "sooty" than the MotorCraft and filling up the filter more quickly. I'm going to change the oil back to MotorCraft and see if it helps.

Bottom line -- anyone had a similar issue?

 

Wow! That’s gotta be killing mileage. Duramax is around 700 miles between regen. Sounds like a perfect candidate for a delete.

 

Can't delete where I live in Colorado.

 

You can't delete anywhere, doesn't mean people don't do it.

You need to post this in general BTW. This is the wrong forum.

 

Yeah, federal law is a bitch! lol

 

Definitely will get a lot more responses in general or even tech. I’m interested to hear what others say as well.

 

DPF filters can be cleaned. They have to be removed to do it, but it's cheaper than buying a new one. It's strange that it happened with so few miles on it. Regen problems in commercial trucks happen closer to 350,000 miles or more.

 

Took my truck to a DPF cleaning shop here in town. He took more than a pound of built-up soot out of the filter and was pretty sure that was the source of my issues! Haven't had a chance to take it on a long drive yet but fingers crossed this puts me back to a normal regen cycle.
