Slovakian fuel prices have converged to the point where the difference between petrol and diesel is almost negligible, with some stations listing both at the same price. This unusual situation, reported by local media, stems from differing tax rates applied by the state to each fuel type.
Currently, diesel is taxed at a rate of €0.368 per liter before VAT, while petrol faces a higher levy of €0.514 per liter. In addition to these excise duties, both fuels are subject to a 23 percent value-added tax (VAT). According to data from the Slovak Statistical Office, as of the week ending February 8th, 2026, 95-octane petrol averaged €1.474 per liter, while diesel cost €1.466 per liter – a difference of just one cent. This contrasts with a four-cent difference at the start of the year.
The discrepancy in taxation is a deliberate policy intended to support businesses and vehicles reliant on diesel engines, according to reports. Diesel fuel, likewise known as gasoil, is a mixture of hydrocarbons designed for use in diesel engines, with a typical density ranging from 0.820 to 0.845 kg/L at 15°C. Its heating value is approximately 43.0 MJ/kg, or 9.7 kWh/L.
The current price alignment is not a typical occurrence. Historical data suggests fluctuations in the price gap between petrol and diesel have occurred previously.

The article also examines Slovakia’s position within the European fuel price landscape.
Across Europe, the terminology for petrol and diesel varies. In Spain, for example, diesel is referred to as “Gasoleo,” while in Belgium it’s known as “Diesel” or “Gasol.” A comprehensive list of fuel designations across various European countries, compiled by the ARBÖ, highlights these differences, demonstrating the need for clarity when refueling abroad.
Diesel fuel, chemically defined as a mixture of hydrocarbons, has a flashpoint exceeding 56°C and an ignition temperature of at least 225°C. It is classified as a hazardous material under UN number 1202, with a hazard number of 30.
