Regen Question
I decided to take my truck for a 300 mile break end drive today and I love this truck. Mpg was 19.5 at speeds of 55 to 65. The only thing I noticed was a message about regen but it was so fast I can't fiqure out what it said. My 6.4 regen would stay lit until end of regen, how does the 6.7 work?
Thanks for any input

(I like the longer message, but have had to clear it a couple times.. don't know what that does 'cancel to clear'...
anyhow.. its still regening even tho the message is not being displayed..

the 6.4 and up trucks have a filter on the exhaust to catch all the smoke... (diesel particulate filter, aka DPF).. when the filter fills up, the system goes into regeneration (regen), to burn off the accumulated carbon particles..
It does this by injecting raw fuel on the exhaust stroke, which flows into the DPF where it causes a fire hot enough to burn off the carbon, and exhaust it as ash..
while that is happening, SOME fuel will get buy the piston rings and end up with the engine oil.. (aka making oil)..
usually more at slower speeds..
course this fuel is NOT used for moving, and thus it cuts down your miles per gallon..
this is done approx every 100 or so miles.. whenever the back pressure in the DPF gets high enough to indicate being clogged.

otherwise no harm, no foul.. if you don't see it, then you don't worry about it.. (they think)

The one thing I know about regen is if you don't finish a cycle it will start all over again until you do. With the less time in regen you will reduce the amount of oil you make. With the 6.7 the longer time you can go until a regen is a plus, but I still want to know it has completed a cycle before I shut it down.
