Your Questions, Answered

Soot and ash build up within your DPF will restrict exhaust flow and disrupt the smooth running of your engine. This will cause excessive fuel use , low power, early engine and associated exhaust stream component wear, and unplanned maintenance and repairs.
Because a DPF is primarily a “Wall Flow” Filter the ash is trapped within the DPF and must be removed periodically.
Cleaning intervals depend on the type of use the vehicle is exposed to. Highway running vehicles need less of a interval (1yr) then school bus or garbage pick up vehicles, these have a far more demanding duty cycle.
A clean DPF ensures optimum engine power, performance and fuel economy, reducing the risk of unplanned maintenance expenses and down time. This will help your bottom line $
