Diesel Oxidation Catalyst Servicing

We keep your DOC running at peak efficiency to help you meet Stage IV and Tier 4 Interim/Final emissions standards. A diesel oxidation catalyst (DOC) effectively turns CO and hydrocarbons into CO2 and water vapor. It breaks down pollutants in the exhaust stream from a diesel engine, helping to reduce particulate matter (PM). 

**Regulations require that the DOC be serviced every 100,000 miles.
