I got the 3M-DFSC treatment done to my 5 year old Fiesta Classic yesterday.
I wasn't very convinced of it's effectiveness due to lack of reviews and even any publicity on part of 3M.
I usually search for team-bhp for all such reviews and found almost nothing here either.
But what tilted me to go for this treatment was a video that was shown to me on a Hyundai Verna that was done only weeks ago at the same 3M workshop.
The results were quite good. It showed an extremely clean exhaust of that car even with the rev counter around 4k RPM.
My Fiesta Classic had resorted to thick black smoke under hard acceleration and was recently pointed out by my friend as I was driving ahead of him on the expressway.
I found this to be unbelievable since we do not observe the lesser smoke from the driver's seat.
It was also hard to believe because I've always used Shell diesel and have carried fuel additives on long road trips where I know Shell pumps do not exist. I'm not going to go in the quality of the fuel offered at Shell in this post, but it certainly is a question popping up in my mind.
Considering my car has completed 5 years and completed just about 50,000 kms (it was largely unused for the last 2 years), I felt it's worth it.
So, the DFSC treatment claims to do ala Liquimoly Diesel Purge. The process is controlled by a machine that regulates the treatment fluid flow to the engine. This is done by connecting inlet-outlet pipes of the machine to the car's engine. The car is then run on idle for 30 mins and then about 10 mins with varied RPM.
The results were quite awesome to say the least.
- Reduced engine noise/clatter.
- Noticeable difference in throttle inputs. This is way different than using fuel additives. Does not feel sluggish.
- No knocking.
- Almost negligible smoke/soot coming out of the exhaust at the same acceleration
Irrespective of the car, this treatment costs only Rs. 4019 incl. GST.
Expensive Germans are better off on proprietary treatments at their respective workshops. But VW and Skoda can surely be done.
I'm not advertising this at all and I do not have any stake nor earn any side-kicks or payouts from 3M.
Here's the location for anyone needing this service in PCMC area.

I have a few photos and a before/after video here. I may have to do something
Removing the engine cover; trace the diesel fuel filter:
Inlet-outlet are attached to the 3M machine; the Green bottle shown in the image below is emptied in the machine's internal tank; 30 mins idle as mentioned above:
