31 miles per Engine hour...

Total hours... how do u find driving hours?

On my EVIC screen it shows driving hours, idle hours and total hours.

Is there supposed to be a photo with this? Or just a random comment?

Average per driving hours isn’t the important one, it’s average speed per total hours. Thou that can be misleading too. I have a low mph average at 33, but don’t abuse my truck with idle time or traffic, but rather lots of slow speed driving on back roads.

For example this weekend I did over 1000 miles with 500 of it being at an average of 58 mph, but the other stuff was slow and my overall average was 33. No excessive idle, lots of slow 4wd time, lots of dirt/snow roads.

I’m currently at 869 hours. 75/794 is my split. 28,9xx miles.

Friends:
The info on my 2017 Ram 5500 is as follows:
Idle: 149
Driving: 861
Total: 1010
Miles: 40485
So, my totals are: AVG Driving Hrs 47.0 MPH is MPH; AVG Total Hours MPH is 40.1 MPH
Percentage Idle time: 14.75%

My numbers really got skewed towing generators into and out of hurricane disaster areas. I was stuck for hours in evacuee traffic and folks returning to disaster areas.

Anyhoo, my numbers should improve as this truck normally tows our RV on trips and other trialers locally, usually ver little heavy traffic.

Cheers, Ron

Well... I don’t have that level of detail on my 2012... only engine hours... just divided my total mileage by the engine hours as I was curious as to the mileage per engine hour... your % of idle time was interesting Wiredawg... I think I am in the single digits but have no way to know accurately...

It is doubtful your idle hours are single digits as anything with the rig stopped, in gear or not, is idle time. Every 2 seconds at a stop sign, 30 seconds at a red light, 2 minute cool-down, stop and go traffic, etc adds up.

8% idle time is considered very low.

Cummins considers anything over 16.6% excessive.

Ahhhh ... didn’t think of it that way...u r right... never factored that in

Here is my latest. I don't feel like I idle much but by the numbers it says I do???

it says I do.

View attachment 126476 it says I do.

Well, I have almost 4 times as many driving hours, but only twice as many idle hours.
So, yeah, a good bit of idling there.

 

[Cummins12V98]

It's rare I ever let the truck idle. I never let it warm up and do very little City driving. I think it likes to round up!

Well I just thought of something I do. When towing our 5er I never shut the truck down until I get to my destination. Fill ups and rest stops it's left running.

That's quite a bit of idle time.
I do crank mine up on cold mornings before going out to get in and drive off, and then I will idle when hooking and unhooking the trailer to let the truck boost the trailer battery for running the jacks up and down and run the slide-outs, but I try to keep that idling to a minimum.

 

[Cummins12V98]

Even with my towing and not shutting down it seems more than it should be.

Interesting... thank you everyone for their comments so far... when I posted this I was curious as to idle time as other threads on this forum viewed idling ina negative fashion... I warm my truck up ALOT... plug it in every night below freezing... remote start and idle for 10 minutes or so... it gets cold up here, but even on “moderate temps”... I idle up... even use the idle up feature..granted only 104k miles but the process has not been negative...as an example... I normally wait for the trans temp to get to 90 degrees before moving out of park

Soooo now u have me thinking,,, idling to warm up the fluids detrimental ?

This forum is great! Thanks for your thoughts in advance

Excessive idling will load up the dpf, cause the ecm to command more frequent and longer regens.
Do whatever you can to keep the idle time to a minimum, and when you do idle for longer periods, always set the high idle, that will help reduce the extra load on the dpf.

Thank you very much... DPF? What is that?

Really?
DPF > Diesel Particulate Filter
This is the unit in the exhaust system that catches and burns off the soot in the exhaust.
