How Much Will a Car on LPG Cost Per Year?

Blog Article

In recent years, many drivers have been converting their cars to liquefied petroleum gas (LPG) to save on fuel costs. But before making the switch, it's worth calculating how much running an LPG-powered car will actually cost over a year. In this blog post, we’ll break down the key expenses involved.  Ile będzie kosztować auto gaz za rok?

1. Cost of LPG Conversion

The first major expense is the LPG system installation, which typically costs:


  • €800–€2,500 (depending on the car model, system quality, and country).

  • In some countries, government subsidies may reduce this cost.


2. Fuel Costs: LPG vs. Petrol/Diesel

LPG is usually 30–50% cheaper per liter than petrol, but it has a lower energy density, meaning higher consumption (about 10–20% more than petrol).

Example Calculation:

  • Car: 1.6L petrol engine

  • Annual mileage: 15,000 km

  • Petrol consumption: 7L/100km

  • LPG consumption: 8.5L/100km (approx. 20% more)

  • Petrol price: €1.50/L

  • LPG price: €0.80/L


Petrol cost:
15,000 km × (7L/100km) × €1.50 = €1,575/year

LPG cost:
15,000 km × (8.5L/100km) × €0.80 = €1,020/year

Annual savings: €555

3. Maintenance & Additional Costs

  • Oil changes: More frequent (every 10,000–15,000 km) due to LPG’s drier combustion.

  • Spark plugs & filters: May wear out faster.

  • LPG system servicing: Recommended every 20,000 km (€50–€100 per visit).


4. Insurance & Taxes

  • Insurance: Some insurers may charge slightly more for LPG-converted cars.

  • Road tax: In some countries, LPG cars qualify for lower taxes.


5. Payback Period

If installation costs €1,500 and you save €555/year, the system pays for itself in:
€1,500 / €555 ≈ 2.7 years.

Conclusion: Is LPG Worth It?

✅ Yes, if:

  • You drive high annual mileage (15,000+ km/year).

  • You plan to keep the car long-term (3+ years).

  • LPG is widely available in your area.


❌ No, if:

  • You drive very little (under 10,000 km/year).

  • You plan to sell the car soon.

  • LPG stations are rare where you live.


Final Estimate: Annual Cost of an LPG Car

























Expense Estimated Cost (€)
Fuel (LPG) €1,000–€1,500
Maintenance €100–€300
Insurance/Tax Varies
Total (approx.) €1,200–€2,000
