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.
