Ya, if it wasn't for that darn 100k mile engine warranty, I would be deleting in 4k miles. (at 60k when the other warrentys stop)

Yeah I agree but I'm only about 98k miles away from that. Have you had any issues with anything?

I bought mine used. I have only put 1000 miles on it. No problems or complaints so far.

I live in northern Alberta and have a considerable amount of idle time. In the first 2000 km I have had one regen. In the first 2000 I have averaged about 17 mpg pretty awesome considering the power. I think the regen is based on driving habits a diesel needs to get to temp and stay there for some period of time to get everything hot and cleaned out. So take her for a long drive every once in awhile and get her hot.

Okay guys I put a edge insight CTS in my truck to monitor more parameters and dpf regen status. This thing fills up quick!! I have 2100 miles on the truck and have regened 4-5 times. Have y'all shut off down during a regen before?

I've stopped worrying about Active regens. They come and happen as the truck requires them. If I need to turn the truck off, i shut it down, I don't even glance at my Edge to see if I'm in the middle of regen. It just doesn't matter.

I have shut down in the middle of a regen. When you start the truck up it runs just fine and will start counting up soot % just like any other start up, It will not start a new regen until you reach the trigger points ( around 2.70%) The truck doesn't restart and immediately say, "OH I didn't finish my last regen, Gotta start one right now". It just goes about doing it's job until the sensor it the trigger point.

So lets say I start a regen at 2.70% and it cleans down to 2.30% and I shut the truck off. When I restart the truck, I might have to drive 50 miles before the count again climbs from the 2.30% to the trigger point at 2.70%.

What is the difference in doing a full regen for 10 minutes or doing two regens that are only partial and only ran 5 minutes each? Other than the drivers paranoia about a regen. You don't loose any power, Most people can't tell while driving that the truck is even doing a regen.

The exhaust system does partial passive regens all the time. Every time you get exhaust temps above 572°F a Passive regen is taking place. Most passive regens are short regens. While you climb a grade type of stuff. Watch you Edge CTS soot % display and you can see it climb and drop as you drive.

I think way too many owners worry too much about this. It's a non-event, Let the computers do their thing and just drive your truck.

I'm not worried about it I was just simply stating it filled up quickly and I'm sure ford took it into consideration about not being able to drive it till it's done cleaning. I just think about the heat and fuel being pushed through the turbocharger.
Which brings me to another question. Why do y'all think ford kept post injection instead putting a injector in the exhaust like Chevy? What do you think the advantages and disadvantages are?

Figured I'd ask in the thread that is already along the same lines instead of starting whole new thread.

I've never heard of raw diesel being injected into the exhaust system. Do you have the artical that talks about that?
