Actually works..
This stuff does exactly what it says.. I get a good clear out of particles after adding and more miles to a full tank.. I have a 2011 car and this is my new go to.. I use once every 2 to 3 months as I clock up some miles and works better than previous ones.. definitely on re order

As described, it is okay
It does the job, the engine seems less vibrate during cold start and more responsive for my 10 years old C4 Picasso.

STP Diesel additive
Good priced bundle. Arrived on time - although courier left package on front door step instead of back door as instructed. Not yet used as waiting to reduce fuel in tank before treating. Hoping for improvement in MPG and performance...
