Fuel quality monitoring includes the quality control of petrol and diesel fuel as well as light and heavy fuel oils and biofuels.
Overview
Air quality directly affects our health and the environment around us. Therefore, different environmental requirements have been established for liquid fuels used in internal combustion engines and as fuel oils. Continuous monitoring ensures the use of high-quality fuels in Estonia.
Information about petrol stations and stationary tanks and the results of fuel monitoring are available at the fuel monitoring database.
As of the end of 2025, the database contains 517 petrol stations. The largest number of petrol stations are in Harju County (179), followed by Tartu County (61) and Pärnu County (43).
According to the fuel monitoring database, the quality of motor fuels sold in Estonia has improved considerably over the years. In 2024, 600 fuel samples were taken from petrol stations. Four samples did not meet the requirements. One case involved non-conforming paraffinic diesel, and the other three involved petrol failing octane number requirements. Non-conforming samples were taken in Jõgeva County (paraffinic diesel), Lääne-Viru County (petrol 98), Viljandi County (petrol 95) and Rapla County (petrol 95).
In 2024, 73 fuel oil samples were taken. There were four samples that did not meet the requirements. The requirements were not met for the zinc and water content of oil shale oil. Non-conformities occurred in Rapla County (water content), Pärnu County (water content), Viljandi County (zinc content) and Harju County (zinc content).
