Due to their fuel combustion processes, diesel engines emit more exhaust contaminants than standard gas motors. As such, vehicles with this type of engine are outfitted with a diesel particulate filter (DPF) to remove harmful impurities. While the filter is effective, it must be cleaned about once every 100,000 to 150,000 miles to remain fully functional. If you drive with diesel, the following are reasons why routine DPF cleaning is essential to your vehicle’s functionality. 

5 Reasons to Regularly Clean Diesel Particulate Filters 

1. Fuel Efficiency 

When too much particulate matter collects inside the filter, pressure can increase back into the engine. Over time, this backpressure reduces fuel efficiency. Without DPF cleaning, drivers will find that they must fill the tank more often and bear the cost of increased fuel consumption. 

2. Emissions Compliance 

Environmental protections put in place by state agencies, the EPA, the NHTSA, and the Clean Air Act require diesel vehicles to be equipped with maintained DPFs. If the filter is not regularly cleaned, harmful pollutants enter the air, putting environmental and public health at risk. When it's time to undergo emissions testing, trucks without clean DPFs may fail and might be deemed illegal to operate on the road. 

3. Enhanced Performance 

The same backpressure that impairs fuel economy also makes it more difficult for the engine’s turbocharger and the intake manifold to function at full capacity. Put simply, these effects can deplete the amount of air the engine receives, resulting in less power, speed fluctuations, and overheating.  

4. Minimized Repair Needs 

If a dirty DPF is kept in place too long, the resulting performance problems and increased exhaust debris cause wear and tear on the engine. Besides contributing to possible breakdowns, this added stress requires more frequent auto repairs and parts replacements. These repairs add to vehicle maintenance costs and increase driving downtime. 

5. Longer DPF Lifespan

With proper maintenance, a diesel particular filter can last the life of the vehicle. However, if contaminants build up and wear down the part, it will eventually need to be replaced. Since these filters are expensive, it’s more cost-effective to clean them according to the manufacturer’s recommended schedule.
