Diesel Kleen to clean DPF?

I have a 2010 6.4 F450 with 106K miles on it. I was on a longer trip and on the way back home. As I was going up mountains, I started losing power and the emissions indicator came up on my dash.

I had noticed that the truck hadn't done the regen for a few days while I was driving relatively slow through Yellowstone/Tetons for hundreds of miles. The text that indicated the regen process did come on for a few seconds along the way.

I was hundreds of miles from home with plenty of mountains on my way. I felt like I needed the DPF to clean, but knew I couldn't manually trigger it. While eating supper, I read an article that was talking about how DPF cleaning additives work. That got me thinking that maybe using a lot of Diesel Kleen could possibly get the truck back to normal.

So, I bought a large grey bottle of Diesel Kleen that is supposed to treat 250 gallons and added it all to the tank and filled up the tank. Maybe a partial waste of $18, but I didn't think it would hurt anything.

I engaged Tow/Haul and started driving. After about an hour of driving, the regen process engaged and completed. We camped for the night.

I didn't add any Diesel Kleen in my next fill up since I thought it still had plenty. The truck continued to regen as normal on the rest of the way home and full power and I added a normal amount of additive on the way home for each fill up. After a few regens and restarts, the emission indicator went off on one of the restarts which implies it thought everything was ok. It stayed off the rest of the trip.

1. Have you done anything similar to the overdose of Diesel Kleen to clean your DPF and get the process going?
2. Do you think my DPF regen is back to normal now or should I have it checked out?
3. It seems like the regen process refuses to start if the DPF is "too" clogged. Is this what others have experienced?
4. What the best preventative measures to take to prevent a recurrence? Driving at higher rpms, adding more additive, both, or something else?
