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.
