About LPG

What is LPG?

LPG (Liquefied Petroleum Gas) is a hydrocarbon mixture consisting predominantly of a mixture of propane and butane, obtained by refining petroleum or directly from extraction, after having been separated from natural gas or oil with which it has been mixed in the oil fields.

  • LPG for vehicles is clean; it does not contain water or other impurities, it has a complete combustion and does not generate carbon deposits on pistons, spark plugs or rings.
  • In order to prevent and minimize fuel hazards, the LPG industry developed a number of standards and guidelines in the design, production and installation of LPG components and equipment, which are continuously adapted to technological developments.
  • Liquefied Petroleum Gas is a safe and clean fuel that has been used for years for cooking and heating. It is not toxic; it is not poisonous and does not contaminate water and soil. LPG has the lowest flammability range of all alternative fuels. Moreover, its ignition temperature is half than that of gasoline. LPG for vehicles uses a sealed system with valves that close and transport the fuel from the pump to the tank without environmental exposure, thus preventing leakage and evaporation.

The advantages of LPG use


  • Liquefied Petroleum Gas is a fuel that is obtained at a relatively low cost. Retail price at gas stations is 50-60% of that of gasoline.
  • Due to the lower density of LPG as compared to gasoline, consumption expressed in liters will be up to 10% higher than that of gasoline. At least 40% of the fuel cost will be therefore saved.
  • In Romania, by investing in LPG the same amount used to pay 10 liters of gasoline, a vehicle can cover 40% more distance than using gasoline.
  • The investment made in setting up a gas installation can be retrieved in a relatively short time (about 10,000-15,000 km), even if only through the cost difference between gasoline and LPG.


  • LPG is an excellent fuel for vehicles that need to obey increasingly stringent pollution standards.
  • NOT TOXIC to soil and aquifers in the event of accidental leaks.
  • The combustion of LPG produces up to 15 - 20% less CO2 as compared to engines using gasoline. LPG also releases 97% less benzene than unleaded gasoline. This fuel uses a sealed system, with almost no emissions of hydrocarbons!
  • Finally, an additional benefit is that in case of overflow, LPG evaporates a lot faster than gasoline or diesel. As compared to gasoline and diesel, there is no risk of contaminating the soil or the water.
  • Moreover, the vehicles are less noisy than those using gasoline or diesel, thus reducing the noise pollution.
  • The structure of the mixture depends on the country climate and it is regulated by the European standards adopted in Romania under the SR EN 589-2002 norm.
  • LPG is now the fuel for a cleaner future.


  • The containers are made of special steel (treated against cracks), with a thickness of 3.5 mm. They are fixed to the vehicle with flats and supports sized to guarantee good anchorage of a full tank in cases of extremely high acceleration or deceleration.
  • The gas tanks for vehicles are made of a special alloy, 20 times more resistant to puncture than the gasoline, methanol or ethanol tanks.
  • The new cylindrical tanks are built using a device that does not allow tank filling of more than 80% of its capacity, which allows gas to expand its volume without leaking, if temperatures rise.
  • The tank will only fill up to 80 % ± 3 % of its capacity, due to the special device attached to it, ensuring thus the presence of an air gap for gas expansion.
  • If the engine has been accidentally switched off, the electrical CAR SAFETY system closes the gas supply in three parts (on the back side of the tank and on the two front solenoids).
  • LPG has the lowest flammability range of all alternative fuels.
  • LPG and air will not ignite unless the heat source temperature reaches at least 940 degrees Fahrenheit. As opposed to this, a gasoline source will ignite if the heat source temperature reaches 430-500 degrees Fahrenheit.
