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...

DEF can increase the combustion temperature according to Volkswagen, for instance. http://www.volkspage.net/technik/ssp/ssp/SSP_330.pdf At least, I'm assuming their additive is the DEF.
System with additive
This system is used on vehicles where the particulate filter is installed away from the engine. Due to the distance the exhaust gas has to make from the engine to the particulate filter, the required ignition temperature for combustion of the particulates can only be reached with the introduction of an additive.
The question is "do other additives" help as well. If so, in extreme circumstance like slow driving would it be advantageous to change the amount of additive and/or change the driving method if possible to prevent a potential clogged dpf issue.
Quoting Volkswagen on emissions. Now that is funny...
DEF does not directly affect temperature of anything in the system. It does not generate heat like diesel fuel does when it is injected in the system. DEF controls NOx and therefore allows manufacturers to tune diesels to run a bit hotter than DPF trucks that do not use DEF. Additives do nothing to build heat.
