Seems to work...but I don't have an ecodiesel x-ray machine. :)
Only time will tell, but we use this in all of our cummins for years without issue.I use this every fillup on my jeep jl ecodiesel.

It works!
This stuff works! It has improved my fuel mileage and I’m sure it works it’s magic in other ways that I can’t see. I will however buy it locally as I can get a better deal on it.

I used other products and without a doubt this is the best. A good Freind of mine questioned this product ...
My 2012 f350 6.7 is running way smoother with this product. I used other products and without a doubt this is the best. A good Freind of mine questioned this product so I bought him a can for his 6.6 duramax. Now this is all he uses as well. The oil is great as welll.
