Regen question ???
Will using Block heater every morning be beneficial to the 6.7's exhaust/smog system in 30 to 50 degree temperature? Mild winter in southern Oregon. Coming from a 7.3 to a 2017 6.7. Will it reduce Regens???

Your DPF is what will fill up when driving and require a regen. High speed highway driving and pulling a load both require the engine to work, and at higher temps, which will facilitate passive regeneration. Short trips, stop lights, and especially idling will produce soot in your exhaust stream, which the DPF will catch, and eventually you will see a "Cleaning Exhaust Filter" message...this is an active regeneration...fuel being injected into the exhaust stream to burn off the soot on the DPF filter. The block heater won't aid in this. Would be cool if it did though!

It's very easy to manage...drive it any way to want, feed it fuel and DEF...it will tell you if it needs anything else...right there in the productivity screen.
If a regen starts, and you need to shut down, no worries...it will restart when you hop back in. If you do this a few times without a good drive between, you may see a "drive to clean" message...I've never seen this, but hear tell of its existence...just asking for a good high speed/rpm drive to clear out. These engines are amazing, don't complain much, and always have more snort to offer. Enjoy and welcome!!

To answer your question in a slightly different way, using the block heater is good from a regen perspective - if the alternative is idling. As already pointed out above, idling will allow soot to accumulate in your DPF, so you'll need to regen sooner. Plugging in your block heater doesn't produce soot. Therefore, if it's (very) cold out and you want to make it easier to start, the block heater is better for regens (and fuel economy).

That was my thought, warmer block, maybe warmer oil, . Having a 7.3 F350 for 19 years I often used the Block heater when it was 20+ thru low 40's, 7.3 ran smoother, stronger, and more fuel efficient when the block heater was used under certain conditions. I understand for the 6.7, don't idle long periods of time, avoid stop and go traffic and work it for best passive regen ( higher temps) . Trying to get to higher Temps sooner with Block heater during cold weather for reducing Regen was just a idea did not prove out. Hey Ford how about a plug in ac Regen in the garage why we sleep, of course we don't want to burn the house down. Just another thought.

I think we're on the same page, but just to be clear. I'm saying that, from a regen perspective, the block heater is better than idling. Using the block heater, in and of itself, is not a technique to reduce regens - at least not to my knowledge.
