Should I get a Diesel

[star_deceiver]

I wonder about the stick shift though, in my truck it cuts fuel while also dropping a gear, did your previous trucks cut the the fuel too when you manually downshifted while going down a hill? I don't know how important that fuel stuff plays into this, just that I think I can feel when the fuel cuts in and out (which is separately from the downshift itself); first it downshifts, then it revs up and then all of a sudden it seems to "grab" a bit more? And then if you're slowing down it reaches a point where the brake stops braking pretty quickly even though the gear doesn't change.

I could be way out to lunch of course.

I doubt the ‘16 Cummins w/G56 cut fuel. The DPF would cool down too much. It more than likely post injected fuel to keep the after system stupid hot.

The 845re with the 3.6 seems to drop 1 or 2 gears depending on how far I push the brake pedal but doesn’t take the engine over 3000rpm as I recall. Putting cruise control on it will drop more gears to try and hold its speed so long as I don’t touch the brake.

In T/H it will drop more gears and sometimes bring it to 4000rpm. For a small engine, it works fairly well.

I still miss the exhaust brake and stick shift. I don’t miss the regular cab, dump truck dually ride, or changing fuel filters in the winter.

Yup. No questions asked... get the diesel. I have had my truck regen at 50-60 mph multiple times and never had an issue. Just be diligent and take it on the hwy for 15-20 min at least once a week if you can. Even then, if you are getting to 50 mph for a decent amount of time, I bet it regens just fine.

They regen while you drive between 50-60 mph?

Yes. It isn't the 'active' regen that tells you to keep driving, but if you scroll to the DPF status screen it will say 'automatic regen in process.' Get it every few weeks driving back and forth to work at 55 mph, approximately a 45 minute drive. If it starts to regen partway through the drive, it will usually start back up immediately when I start the truck again, and finishes before my trip is over.

Then it's a good thing I never got a diesel. I live rural and I don't get my truck over about 45 MPH more than maybe 3 or 4 times a month.

I usually get the automatic regen on about the same frequency as you, usually when the dpf status is anywhere between 45-50%. When it does that I just pass up my exit to work and cruise down the highway, flip back around and it’s usually done by then. I drive 30 miles to work mostly highway one way. I don’t want to ever have an issue with a full dpf filter because the exhaust got cool and the regen cycle never finishes completely.

I don't know. I had an 18 2500 CTD and have a 22 2500 CTD. I'm sure they've done regens, but I never knew about it or noticed it. No regen messages, even when watching the DPF gauge.

If you have the DPF gauge up it should occasionally switch to saying 'Automatic Regen In Process.'

But where you WILL notice it is in your fuel mileage and your boost. On my typical drive to work my instantaneous mileage reads anywhere from 25-30 on flat ground, and my boost gauge is at zero. When I am in an Automatic Regen, my mileage in the same spots drops to 17-18, and I'm running anywhere from 1-2 lbs of boost.

Are you going to delete the regen system?

Are you going to delete the regen system?

Not until my warranty is up. If something happens before then, well, I guess Ram can pay for it.

So I hear. But I've never seen it. I'm pretty much done watching the DPF gauge. I watched it quite a bit on my last couple of pulls just to see if that message would come up. Nada.

Again, never noticed it on either truck. Towing MPG and power is pretty consistent. Mine is not a daily driver, it's a puller for our toys.
