anyone notice that after a Regen Cycle on a 2016 6.7 PS the fuel economy starts getting worse unless you turn off the truck and turn it back on? Seems to be the case with mine and I only have 8400 miles on mine.

After I get the exhaust cleaning message, mine does start to drop. I am in no way mechanical but I'm assuming it's burning extra fuel for the cleaning process.

Hello. It does burn extra fuel to get the temp up to use def to clean the SCR.

You burn 1.5 - 2 gallons of extra diesel during a full regen. Your EGTs go from 600-700 to 1,100-1,300.. raw fuel is being injected into the exhaust stroke of the motor.

Reduced fuel economy from increased exhaust back pressure
Increased fuel burn from active regeneration
Increased exhaust temperatures may reduce engine life
Increased backpressure may reduce turbo and engine life
Increased aggravation with complexity of emissions system shortens my life.

I have two main EPA grips over the past 10 years:
Number 1: Diesel emissions have destroyed long term reliability of engine.
Number 2: Who ever mandated those stupid fuel can nozzles has never used a 5 gallon fuel can to fill an ATV or car with it. They should be treated a public enemy number 1.

I will keep my Diesel instead of going back to an F150 EcoBoost and deal with all the problems of gas engines. We will see how much mileage I get on the diesel, bc my EB engine needed a lot more stuff fixed at the 60K mark then my PS will

Only thing about the PS6.7 that so far has annoyed me is after the Regen Fuel economy goes down for next 50-60 or so miles other than that at nearly a year old and with 18,000 on it I am happy with my 2016 F350 6.7 PS SCREW, SB King Ranch

Has anyone done the DPF or DEF delete and run a time on a 6.7 PowerStroke? I am thinking of going this route once the warranty is up on my truck the def and regen cycles kill my MPG bad

That's funny, because at 30,000 I'd had zero issues with my 2013 EB, but my 2015 F250 6.7PSD has already had $3600 in warranty repair done to the exhaust/emissions systems and has just over 17K on it.
