Inserted in a Mazda 3 Diesel with 100.000km built in 2006. The injectors caused a relatively loud combustion noise and I wanted to get clean again with Cleaner. Any statements about lower fuel consumption, better pulling power, more power, depends more on gas, runs quietly and so would be without proof on a calibrated test bench without three comparative measurements anyway implausible. Therefore I leave it and stay with the facts ... product has caused no damage to the engine, CR pumps or Injektorenschaden. (After 2000km service life)
