Gearbox was dripping oil big time, after using hardly any sign at all! C Citroen Red Racer The best product to clean your diesel system include turbo charger. Its helps to unblock turbo charger (with changeable geometry) if that stuck. That far cheaper than replacement of the whole set. I’m so pleased with that product. A Alexey Firsanov Perfect product, solved the blocked dpf problem. Will recommend it to any one with dpf problem. A Albert Boateng Very good indeed cleaned the DPF and turned off the EML .highly recommended B Bryan P. I used this in my brothers diesel van as it had a flat spot on acceleration, and the fiat stop is clearing steadily. We have used Wynn's product's for many years because they do the job.. I would recommend this. P Pes Used this stuff since the late 1970's, it does what says. S silverbeatle1 Have used Wynn's products for over 40 years and have never had any problems. I would also recommend the oil additive which have also used many times. J jamesd6512 This is the first time I used this, it is brilliant As soon as I put it in, the car was more quiet and is running real smooth.. I would recommend this to fellow drivers. A Actual Ace Water in a diesel fuel tank can enter via the pump or by condensation. Either way, in very cold weather this water can freeze in the fuel filter. This means your engine may not start.... Not good up in a mountain! Good stuff R Richardhsharker
