Does DPF Delete increase MPG?
Yes, in certain cases, DPF delete can increase MPG. Diesel Particulate Filters (DPF) are a part of a vehicle’s exhaust system that is designed to reduce diesel vehicle emissions by filtering out soot particles that are released when burning diesel fuel.
Although DPF’s are an important part of keeping vehicle emissions low, they can put an extra strain on fuel economy because they require additional exhaust flow which causes increased backpressure and losses.
Since DPF’s restrict the exhaust flow, a DPF delete can improve exhaust flow and help the engine to run more efficiently, thus resulting in improved MPG. Keep in mind, however, that a DPF delete should not be done without first consulting with a professional, as removal of the DPF and the required re-programming of the engine’s ECU usually requires more specialized knowledge and can damage the engine if not done properly.
Moreover, it’s important to remember that regulation of diesel exhaust emissions is very important in order to protect the environment – so it’s best to consider other potential solutions first before opting for a DPF delete.
