How often do you have to Regen a Freightliner?

It depends on the application, how many miles you drive per day, how many hours you idle your truck, if you’re a local driver or if you make a lot of stops per day or often sit in traffic.

Generally if you're a long haul truck driver, roughly about every 4-7 days is a sign of a healthy exhaust aftertreatment system. Local truck drivers should generally need a regen about every 7 days or more possibly. Again this also depends on how often your truck or if it does at all do highway regens.
