As the above data show (obtained 10 hours after the start of the test cycle with a fuel tank volume of 300 liters), using the recommended dosage provides excellent cleaning of the injectors of the Peugeot XUD9 engine.
Tests to evaluate the cleaning performance of the Maxxrecovery Diesel Additive Clean & Protect Truck composition and to protect the injectors from deposit buildup were carried out using a 1.9 liter Peugeot XUD9 engine, in accordance with CEC F-23-01 procedure. Typical results obtained in these tests, expressed as a proportion of deposits at a 0.1 mm needle travel, for diesel fuel, both in the absence and presence of biofuel additives, are shown below.
