Manual regen

So my truck decided to go into regen mode right when I got home, so I used my edge cts2 to do a manual regen just for kicks and giggles to see what it was like(donít think the elderly neighbors liked it to much). Anyways it said that afterwards a oil change may be necessary, is that true? I have 78% oil life and I run mobil one synthetic. Just curious under what circumstances that a oil change afterwards would be required.

A stationary regen gets everything extremely hot even compared to a normal regen where you have plenty of forced air cooling throughout the engine compartment. I suspect GM feels the temperature generated during a stationary regen may degrade the oil sufficiently to require a change.
When GM introduced "camel mode" (allows the engine to safely run at reduced power after cooling system failure by alternating cylinder banks) for some of the Cadillac engines a number of years ago once camel mode was engage the change oil message automatically popped up.

I wouldn't run a stationary regen unless absolutely necessary (as in DPF couldn't clean itself in normal operation thus requiring a forced stationary regen to clear the codes and reduced performance restrictions).

I usually run a manual monthly on my work diesels. Have had problems with the DPF in the past and the dealer suggested once a month. When I run it manually, it seems to do a significantly better job of cleaning as there is white smoke and the tailpipe gets roasting hot. I do not do any oil changes afterwards. If you monitor the engine temps it does not run any hotter during a regen so I assume it is not doing anything bad to the oil.

If anyone is curious and wants to watch a really dull video, I did a manual Regen on my stock LML with the Edge Insight CTS2 this A.M. to get a baseline for how often the DPF needs to get cleaned under "normal" (for me) driving using Opti- Lube XPD.

So just for fun, if you go to this channel, you will see three vids. And yes, it is scary the first time you do it.

And have one of these handy.
