Oil changes and DPF regen

[roflcopter]

I know regen discussion gets beat to death around here... but I found an interesting thing in the Diesel Supplement that made me raise an eyebrow.

On section 3, page 21 it discusses regens and the messages that can be displayed, before going into the Chassis Cab specific stuff it states the following:

"NOTE: Failing to follow the oil change indicator, changing your oil and resetting the oil change indicator by 0 miles remaining will prevent the diesel exhaust filter from performing it’s cleaning routine. This will shortly result in a Malfunction Indicator Light (MIL) and reduced engine power. Only an authorized dealer will be able to correct this condition."

Am I reading this right? It seems to imply that changing your oil before the truck tells you to (along with resetting the life meter) can actually CAUSE issues with the DPF?

My theories:

1) They use the oil life remaining mileage to key off of for the scheduled regens and by resetting the counter it keeps it from hitting its mark and performing one? Seems odd to not just use the real mileage, unless they are piggy backing the load calcs this way too.

2) Someone has no clue what they're talking about when they wrote that note.

What're your thoughts?

I think I read it the opposite. Taking the excess out gets us this...

"Failing to change the oil by 0 miles remaining will prevent the DPF from performing it's routine."

Maybe once you go over, the DPF cleaning won't occur as needed.

I read that as going "Past" the oil change interval will cause an issue, Not doing it early. Kind of crappy of them to tie Regens to the oil indicator though, it's just a way to make sure you do the oil changes or you'll end up at the dealer.
In all honesty though you could just reset the oil life meter and problem solved, it doesn't know if you changed the oil or not.

Ah, that makes more sense...

seems someone forgot a second comma... Should read:

"NOTE: Failing to follow the oil change indicator, changing your oil and resetting the oil change indicator by 0 miles remaining, will prevent the diesel exhaust filter from performing it’s cleaning routine."

Maybe they should have just used some parenthesis... I do a lot of documentation work so maybe my brain was looking at it too literally.
