Review: Great product. Use before your MOT - I have used this for years now and I buy this every year before my vehicles have their MOT. This will honestly help with the emission test. I was sceptical at first when I was recommended it but I have years ago had a vehicle fail and one bottle of this completely changed the result. I have not had one vehicle fail on emissions since using this product. I would use this two or three weeks prior to your MOT and let it get to work and it will definitely have a positive impact on the test and help your vehicle.
Review: Essential - A good cleaner that is easy to apply - simply add it to the fuel tank, following the instructions carefully. It can make the difference between your car/van passing the MOT or not and by keeping your catalytic converter clean, your mileage is optimised. The longevity of the converter is maintained and given that it is one of the most expensive items needing replacement on diesel vehicles, that's important.
