    I know it's not a good idea to idle with these epa10 engines, but what about when it's below zero? Does that harm the engine or the after-treatment?

    No more harming than gelled up diesel/not cranking engine in the morning.

    Between clogging the DPF and letting the fuel gel, I'll take a clogged DPF any day of the week, twice on Sunday. Even with winterization, cold enough weather can and does gel the fuel

    Your fuel returns should keep the tanks toasty relatively.

    I run the engine in anything below 10 above. Particularly -20 and below. PRe emissions time I have never had a engine give trouble when running all the way down to -55 local temps although it's clear the rig is having a form of arthritis due to the lube oils and many temps being colder than usual. We have had experienced temperaturs inside the cab and sleeper into the 50's, warped cab doors and so on.

    They have the DPF filters I would say figured out today. The DPF is working at idle and at highway speed. It's catching all the soot. When idling it fills up and the computers do a parked Regen by pumping diesel into exhaust and lighting it on fire to get the DPF upto 800f-1,000f

    It does the same thing going down the road. Now the engine and exhaust gas is already hot enough to keep the DPF hot and burn all the soot all day as your driving. The first engines with DPF like the old S60 always would put oil and diesel into the exhaust when you idle them. That would mess up the DPF. The new emissions engines don't do that. Now the truck even do automatic parked Regen. They don't wait till the DPF is so full. The Freightliner just does it every 6 hours of idling.
     
    Frontman Thanks this.

    You go sleep in the drivers lounge?

    Def will freeze too.
    Idle wont hurt, can fast idle to bump up the oil pressure, it’ll regen if needed.
