I now have 1,500 miles on my new Ford Super Duty. I have noticed that about every 200 to 250 miles a message appears in the guage cluster indicating "cleaning exhaust filter". Immediatly the fuel consumption increases substantially. I reset a trip odometer once when this happened. It took 28 miles at 65 mph and indicated fuel economy during this time was 10.6 mpg. This is driving empty, not towing. Is it normal for this regeneration to occur so often and also to use that much fuel during the regen? My dealer says it is. Maybe that is why I can't get over 15 mpg of mostly empty freeway (except for a quad in the box)travel.

No, it is not normal unless you idle the engine excessively. You can check the idle hours in the message center. It is normal for the exhaust cleaning to run a few times when new, till the computer adjusts. If you are driving normally and not idleing excessively, you very well may have a problem.

I have a 2016 with about 5500 miles. I would say that's normal from what I am seeing.

The 28 miles is what I thought to be a bit much, I have never seen it go near that long.

I think mine cleans the filter about once every 450 miles. I think it may have done it more often when it was new. What axle ratio do you have?

Sounds normal to me.

I see regens at 400-450 miles running empty on the highway.

It increases in frequency to 250-300 miles when I do a lot of city driving under 50.

This has been pretty consistent for the last 15k miles.

you do a lot of city driving? it will regen more if you do, highway or working hard is what the new diesels like.
keep in mind your truck is also not even broken in yet, my previous 2011 6.7 didn't start getting about 16mpg until about the 20k mile mark.

my 2016 f350 dually with 4:30 gears gets 15.7mpg empty and just a tad over 11 towing, She only has 6k miles so im hoping by this time next year to gain maybe 1 mpg.

So does the Cummins and Duramax operate the same way and as often? My axle ratio is 3.55.

Regen frequency will depend on how the truck is driven such as short trips, stop and go driving, long freeway miles etc. each situation is different.

I have found a fuel additive that reduces the frequency of regens. Do a search for "Amalgamated Fuel Additive". The regen process uses a lot of fuel, so reducing the frequency makes a huge difference. From my experience, regens only happen 1/3 as often, and this additive also increases cetane. The winter blend has additional ani-gel properties.
