An over-consumption of fuel can have 2 origins :
– Too much friction between metal parts in the engine causing power losses.
– A clogging of the fuel supply system which causes pollution and over fuel consumption.
2 actions are therefore necessary to reduce fuel consumption as much as possible:
– use an anti-friction oil additive
– Clean the fuel system and injectors with Anti-Pollution Treatment (Diesel or Petrol), then complete with Injector Cleaner (Diesel or Petrol) or High Pressure Injection Protection Cleaner.
