Idling a 2020 Cascadia

if you are able to high idle your truck it will keep the exhaust hot enough to keep dpf running smooth...my company disables that in my truck so i idle all night at 600rpm and it will do a auto regen every night usually lasts for a couple minutes...and if idle more than 10-12hours i will have to do a force regen(pressing the button on dash) can last anywhere from 30 minutes to a hour .. i have a 16 cascadia, and in the manual they recommend idling at 900 rpm to keep dpf running smoothly.. i would check your manual , it should have all the info u need

 

but ultimatly idling your engine is just adding more wear and tear to all the moving parts on it , not to mention the dpf/def system... being a company driver if my truck takes a #### i get a new one, but if ur a lease/owner op making payments and trying to run a profitable business those idling hours add up over time and just contributing to the countdown to ur trucks death and/or a big repair bill

 

Bottom line is newer emissions engines hate idling for anything more than warm ups and cool downs .
You can idle but It will cost you in the long term .

 

If your a lease driver I would not pay to have an APU put on that truck. What happens if you fail or thy fail and you lose the truck there goes your 10k plus investment down the road. If you owned it sure but on a lease no way.

 

I drive a 2016 Cascadia too, I idle at 900 and it still goes into Regen once a night. Feel like an ### waking up the entire truck stop at night. I just sleep with the truck off and hopefully don't freeze to death in my sleep

 

It should have auto elevate. My 2017 truck does. You can set the idle to 900 rpm. After 8 hours the DPF will fill up. Now the computers will raise the engine to 1250rpm and to a 20 minute regen. That's what my truck will do. Plus it has automatic starts and engine start. The old Detroit Optimized idle system they had in the 90s. Today the computers will do automatic parked Regen. I have timed it just like clock work every 8 hours of idle time entry will Regen DPF automatic.

 

You've got a shore power plug.? It will be a bit of a pain to walk over to the gas pumps, but I'd just get a little generic whisper 2200 watt generater. Seen them as cheap as $350 at Aldi. Burns like a gallon of gas a night. Your truck will burn roughly 10 of diesel a night. The thing will pay for itself in fuel alone in 12 to 14 nights. Not to mention you won't be adding extra wear & tear to the truck.. That's what I'd do before I idled any DPF equipped truck I owned, or paid to maintain..

 

$10k apu is a no brainer.
Save your expensive truck.
You'll quickly incur $10 k in repairs of the def system.
