Over Treating?

Greetings everyone, I have another question...

In regards to treating my fuel with additives, Should I be using PM-22A and PM-23A year round? Or one or the other? I have been using both regularly, regardless of the weather. Another question is if using both, would that contribute to a clogged EGR cooler? I am asking the former because I just replaced said part for the second time in 3 years- this time costing $600 more than the last.

Clogged EGR is from cold exhaust Temps normally associated with excessive light loading or long idle periods.

PM-22 and PM-23 is an either/or situation. You shouldn't need to use them both at the same time.

Pm22 above freezing, and pm23 when below freezing. Not both. They are both good lube for the fuel pump.
