DPF (Diesel Particulate Filter) Intensive Foam Spray Cleaning Kit Made in Germany and Loved by Diesel Mechanics Around The World - No disassembly Required!

5-STARS This is a review on Autoprofi DPF Catalyst Cleaner. I am giving this product a 5-star review. I used one can of spray into the DPF There are 3 ports on my DPF upstream. I was trying to use the upstream pressure port but I could not take off the fitting. Maybe I would have gotten better results if I used the better port to access. I was expecting a lot of white smoke from the exhaust but I did not notice any. No check engine lights came on. Regen mileage interval with NO additives was 384 miles (baseline) after receiving vehicle from repair shop and vehicle working properly. This product induced a decrease in miles between regeneration cycle on first cycle from 384 miles (baseline) to 300 miles, thus increasing DPF regen frequency. My vehicle went 84 miles less between regens with this product on the first cycle. But on second regen cycle the interval miles went up to 515. My vehicle went 131 miles further, thus decreasing the regen cycle frequency. This is an improvement from previous cycle and baseline results. This product had an increase in miles between regeneration cycle from previous product used, Autoprofi DPF Clean (same company). Mileage between regen cycle with Autoprofi DPF Clean was 249 miles. Vehicle went 266 miles further between regens with this product vs Autoprofi DPF Clean. MPG I did not measure mpg with this product. Driving Notes: 35 miles driven during regeneration cycles Soot down to 2 grams, then down to 4 grams on second run EGTs = did not record temperature, normal highway driving EGTs = 721F temperature during regeneration cycle Increase in regeneration intervals frequency on first run (second run showed big improvement though) From baseline: decreased distance between regen intervals, -135 miles (first run) From baseline: increased distance between regen intervals, +131 miles (second run) From previous additive: increased distance between regen intervals, +51 miles (first run) From previous additive: increased distance between regen intervals, +266 miles (second run) I have included other products for comparison below. You should not compare the towing data for comparison. I have just added it to show that towing will change data. Towing will increase exhaust gas temperatures and should make the DPF more effective. My regen mileage intervals increased, decreasing regen frequency, while towing. There are many factors that affect the DPF performance. The factors that I noticed (on my vehicle) are outside temperature, humidity, vehicle speed or stop and go traffic(big factor), and EGTs. Lower temperatures decreased DPF performance. Higher humidity decreased DPF performance. Higher outside temperatures and lower humidity seem to increase DPF performance. Higher EGTs such as towing increased DPF performance. Driving downhill increased soot production faster. Longer driving distance seems helps the DPF filter as optimal temperatures are reached. It seems like soot accumulates faster when the engine and DPF filter are not warm/hot enough, and this seems to occur within the first 10-15 miles of travel. If you are only making short trips then the DPF will not perform well and regens will be more frequent.

Mileage worsened or DPF regeneration intervals decreased in mileage. DPF regeneration process worsened. 3 star: gained less than 50 miles in regen mileage interval (from baseline or previous additive), or slight increase in mpg. 4 star: gained more than 50, but less than 100 miles in regen mileage interval (from baseline or previous additive), or +2 mpg increase 5 star: gained more than 100 miles in regen mileage interval (from baseline or previous additive), or +3 mpg increase.

It takes time to clean it out.i had other cleaner in the tank (50)gallons.saving for next time.

Amazing German product as always. I will buy again and have it at my shop.

It works!
