F350 Diesel Question

[wicked1]

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.

But it helps the Environment!!

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

[wicked1]

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.

Find a mechanic (not a ford mechanic) to talk about all of the issues with the regen cycle. My regen cycle was about every 200 miles and terrible performance when towing. In the city it happened about every 50 to 100 miles. Fuel mileage never went above 13 mpg (highway) 10 mpg city. I get about 15 mpg highway (not a dramatic increase some brag about). Its not cheap and there are legal issues. But I like the performance of my truck afterwards.

That is odd, main reason for my upgrade is going to a 5th wheel F150 doesn't have payload to haul and for a diff of $700 I went to F350 instead of F250.

What went south?
DPF?

Several DEF components were replaced. Pump, heater and others that I can't recall at the moment. If you see a message to the effect of "Exhaust System Error Speed limited to 50mph in 99 miles", get it to a dealer. Even if the message goes away- mine did- it will eventually die and leave you stranded, according to the tech that worked on mine.

I agree that most FWs need a 250/350, but I pull a TT. Price diff between 250 and 350 was going to be several thousand for me- not the sticker price but the true price. I bought in the Fall and there were really good incentives on the remaining 2015 stock. Several thousand better than the new incoming 2016 models. F350s were few and far between, wrong color, and more heavily optioned than I could afford. I found my F250 with camper package, which is identical to the F350, exactly like I wanted it. The F350 badge and a different door sticker just wasn't worth several thousand dollars to me.

WoW!

Thanks for that information big time.

Was it below freezing when this happened?

Did it derate on you or just die?

Don't recall exact temp, but it was considerably north of freezing. It occurred last February, but we were on our way on a camping trip and we hiked in shorts and hoodies- so my guess would be high 50's to low 60's at the time. Luckily was only about 20 miles from a dealer and they got a tech right on it. Was able to reflash and continue traveling. According to message I had 99 miles til speed limited to 50 according to the message. I assume it would have eventually limited me to idle and then not crank, similar to what it supposedly does when you run it out of exhaust fluid, but I'm not positive.

Ok so frozen DEF was not an issue, I ask about that because as I understand the dash thermometer is tied into the DEF tank heater.

If the thermometer is wrong or not working then the heater will not work like it is suppose to.

It has been flippin cold here, 15 below zero Saturday so I was worried a little about that.

New Question - Same Topic Point:
I'm considering a 2017 F350 Dually Lariat (loaded). I read an Edmund's review where they were saying that a properly optioned up 350 could pull a conventional trailer @ 18k lbs without a WDH. I have a Rockwood Signature Ultra-lite which is rated around 10k all loaded up. I don't quite make that but will admit the front is a bit heavy -- I don't think I've ever hit 1k lbs, but possible. Anyway, I'd like to get out of the WDH and sway bar business if I could (getting up there in years and body weight... lol). What would be the consensus? Thinks it's possible or even a good idea?

/regards

Strap in. You are going to get alot of opinions. Some comments you have to take with a grain of salt because they have never driven a dually and have not experienced the added stability on a larger tow vehicle.
I'll give mine. First I run a dually, always will. I tow my 5er camper, a 24' cargo enclosed ball hitch trailer, a 20' open flat 14k pintle hitch equipment trailer, a 30' open flat triaxle, and on occasion a 24' open flat slide deck ball hitch trailer. And I use to have a 32' ball hitch Chateau camper that has been all over east coast and PA.
I got away from using any equalizing hitch at all. I did add airbags just to keep the truck dead level or a little high in the back. I don't feel the need at all for equalizers on a properly equipped dually.
With that said, If I were you I'd get the truck and camper hitched up and check some measurements for rear squat and then go for a test drive. Run it across the scale to see if any weight needs to be transferred to the front axle by use of an equalizer hitch. In my findings I never needed it.
