Is it worth converting a car to LPG?

Yes, if you drive a lot. Today LPG costs 4.78 RON/litre on average, against 9.52 RON/litre for petrol. Even though the engine burns about 15–25% more litres on LPG, 100 km cost 40.15 RON on LPG in our example, against 66.64 RON on petrol.

The numbers at today's prices

Example: a car that uses 7 litres of petrol per 100 km uses about 8.4 litres of LPG. Over 15,000 km a year, the saving is about 3,973 RON a year at today's average prices.

To estimate the payback, divide the cost of the system (ask authorised installers for quotes) by the yearly saving.

What to know

  • The system is fitted by an authorised workshop and the change is approved by RAR, the Romanian vehicle authority.
  • The engine starts on petrol and switches to LPG automatically once warm.
  • Not every station sells LPG: the eCARBURANT data lists 335 stations with an LPG price today.
  • Some underground car parks do not admit LPG cars.
