CITROEN C4 PICASSO GRAND BLUEHDI EXCLUSIVE PLUS EAT6

MOT emissions test for this car is Under 7 for a pass.before fitting my emission was 5 and now it has dropped to 3. I am getting better mileage on the average an extra 5 miles to the gallon, and it is keeping my engine carbon free. I am planning on keeping my car a good number of years,knowing that I won't have any problems farther down the line give me peace of mind. If you are running an older car the savings are greater. Because the newer cars are more efficient to begin with already.
