Cost savings

Fuel cost savings

Fuel cost savings depend on several factors:

  • constant factors: 

    • the density of diesel (0.85 kg/liter) and LPG (0.55 kg/liter).

    • heating value of diesel (43 MJ/kg) and LPG (46 MJ/kg).

  • variable factors: the current price of diesel and LPG

Since the efficiency of the converted and the original Diesel-​ engine is the same, if the price of LPG is 0.55/0.85 × 46/43 = 69% of the price of diesel, there is no saving.  If, on the other hand, the price of LPG is much lower than diesel 69%, then it already results in significant cost savings.

The graph below shows the price savings of diesel fuel after the conversion, for example in the case of HUF 570/liter gas and HUF 275/liter LPG gross fuel prices:


Euro6 és Euro5 járművek esetén még hozzá kell venni az AdBlue (mint egyfajta üzemanyag) megtakarítást is, ami LPG esetén nincs.
