2018 2500 - My first diesel

[Wayne M.]

A quick update:
Temperatures have warmed up (highs in the +30F range) and the miles per gallon have increased which makes me happy. I also bought a Kiwi3 OBD2 adapter and with the Torque app on my phone I can now see DPF Status. I haven't observed a regen yet, it's only been on there a day.

My dad didn't like that Ram only offered 3.42 gears in the SRW applications, so this time he went Ford. I can see why he didn't like them; his top speeds empty would barely get him into 6th. I go a little faster and find them very well suited to an empty truck.

Can you describe or post a screen shot of what your app shows for DPF status?

I would change the diff gear oil in both ends to something suited to your area. The factory fluid is questionable!

I'll get a screenshot of it running tomorrow- its not very interesting with just gauges but no values. Essentially I have 4 small EGT gauges plus a large DPF status dial gauge that reads 0-100%. It was at about 30% when I set it up and has been climbing to I think around 50% over a couple hundred miles.

Snoking, I was wondering what the factory puts in the diffs. After break in I'd like to go synthetic, and probably lower weight. Need to handle occasional -30 to -40F, up to a summer high of 90ish.

75w85 GL-5 full synthetic is factory fill for the 2500/3500.

Here is my screenshot of the custom display in "Torque Pro" the Android app. The DPF Status is a custom pid I found on one of the Cummins forums, and I need to adjust the range of the first EGT sensor.
I'm using a PLX Kiwi3 OBD II bluetooth adapter.#ad

I've observed two regens since my last post, and there was 784 miles between them. They each lasted about 15-17 miles, and EGR 2 and 3 went up around 1000 deg. F. instead of the normal 400-700. EGR 1 had no noticeable change, #2 varied quickly, and #3 lagged. #4 increased a bit but clearly the burnoff was after 2 and before 3.

Also, youd think they could have put just a tad extra DEF capacity in so 2- 2.5gal jugs fit, instead of spilling over with a pint left. I waited till the dummy light came on to fill. I'll just keep it between 1 and 3 quarters of a tank from now on.

Also got oil analysis back on break in oil at 3800 miles. High metals and silicon content, as expected. No fuel, water, or antifreeze, so my trips are long enough to avoid the moisture buildup.

Still love the truck.

Thanks for posting and sharing the EGTs and data. Your numbers jive with what I see with some of the class 8 trucks I handle.
Is there an explanation about the silicon content? Are you running a stock air filter?

Run DEF to 1/2 and add a 2.5 gal box. Has worked for me for almost 3 years and 40K+.

my EVIC is about 6% optimistic when running unloaded, seems to be accurate when laden.

I believe the DEf tank is 5.5 gallons... so two 2.5 gallon jugs will fit... if you are almost empty.

as Snoking stated, run it down to a 1/2 tank and add a jug, you will be good to go

Just made about a 400 mile trip with a Skamper popup camper in the truck bed, into sustained headwinds of 38, gusting to 58 mph for the middle of it, and averaged a whopping 11.9 mpg. Truck performed great and I was monitoring EGTs and DPF status, and it started performing a regen about 15 miles from my end point/fuel-up station. Finished regen about the time the low fuel light came on and I pulled into the station. It was about 850-875 miles since the previous regen. I'm happy and I'll probably quit watching it so close now!

 

[FrozenDEF]

Haven't posted in a long time. I am really enjoying the truck, and no problems so far beyond some bodywork.

I'm up to almost 12,000 miles now.

Got a 14'x7' dump trailer to go behind it. I've used it more than I expected.

Took the Can-Am side by side out for a long weekend behind the camper, about 350 truck miles each way for that trip.

Those mudflaps are putting in time! Cant imagine what shape your paint would be in without them.

 

[FrozenDEF]

I need a middle set! The mud makes it into my front camper tie downs right at the back of the back doors. The back tie downs are clean, it's great.
The pic is my road home. About a mile of that each way, every day in spring break up (a month) and wet fall (another month plus)#ad

You don't live too far from me.........I'm at the top of Skyridge off of the old Steese.
