The STP® Diesel Particulate Filter (DPF) Cleaner is designed to remove soot and carbon deposits from diesel engine filters.

One treatment helps to unblock filters by removing accumulated unburned soot to regenerate the DPF. Ideal for driving styles such as "stop/start," for example, city driving, taxis, and those using their car for short trips, such as school runs.
All diesel vehicles manufactured after 2009 are equipped with a DPF system that traps harmful soot particles and prevents them from being released into the environment.

How it helps:
Unblocks filters
Prevents particle emissions into the environment
Great for stop/start driving
Emission reduction
Treatment rate: Use every 1,800 miles / 3,000 km.
