Severe Service

Overdrive Staff | April 01, 2012

Engine maintenance will pay dividends by extending DPF cleaning intervals. Proper maintenance includes:

• Regular oil changes to keep wear and oil consumption under control

• Ideally, use of CJ-4 oil to extend the cleaning interval

• Minimal idling.

Navistar’s Mark Ehlers says to watch for head gasket leaks that could allow coolant into the exhaust stream, causing a loss of heat that inhibits the system’s ability to burn off soot. Even a small but steady leak of just five gallons over time could cover the platinum oxidation catalyst designed to accelerate regeneration, leaving the unit subject to frequent clogging. Clean the hydrocarbon injector as recommended to preserve the spray pattern. Repair any exhaust leaks right away.
