This is how mine is setup most of the time. Last 3 being dpf sl%(soot level) , dpf rg%(basically a clock until regen starts as once this hits 100 regen will start automatically, and regen status on/off.I am still trying to figure out how I would know how close I am to needing to do a regen.
I see, I was thinking that I was missing something in my owner’s manual that addressed this and told me when the truck performed a regen.This is how mine is setup most of the time. Last 3 being dpf sl%(soot level) , dpf rg%(basically a clock until regen starts as once this hits 100 regen will start automatically, and regen status on/off.
So say your soot level is still low but your regen percentage is 80-90 and it just happens your going to be driving enough constantly at higher speed that could complete a regen. So at this time before you hopped on the interstate or back country road you could go ahead and initiate a regen and have it properly finish.
If it doesn't finish before the trip ends it will resume the next trip.I just think that it would be helpful to know when the truck is needing to do a regen so that you could take it out on the road for a good 30 minutes to get a regen completed properly.
I have decided not to worry about it. The truck will do it by itself and I drive it more than 30 miles at a time at least once a week. I really don’t see anything to worry about. It’s just a truck.If it doesn't finish before the trip ends it will resume the next trip.
Still gets completed 'properly'.
This issue has been debated many many times from the first LMM in 2007 til now.
Truck works for us, we don't work for it.
Since it resumes regen if it needs to I just let it do it's thing.
I refuse to change my driving habits and drive it extra time/distance just because it is in regen.
If that doesn't continue to work, I'll drive something else.
Fwiw, LML regened in about 30 minutes, but the L5P will do it in 20 (at least my '18 did) and the LM2 (3.0L) does a regen in 10 - 12 miles/minutes.
