Polttoainetunnus

Polttoainetunnus, meaning "fuel identifier" in Finnish, is a system used in Finland to clearly label the type of fuel at a refueling station. These identifiers are standardized symbols or codes that help consumers quickly distinguish between different fuel options, such as gasoline, diesel, and various biofuel blends. The primary goal of the polttoainetunnus system is to prevent incorrect refueling, which can lead to engine damage and costly repairs.

The identifiers are typically displayed prominently on the fuel pumps themselves, often alongside the brand name and price. They are designed to be easily recognizable, often using simple geometric shapes or distinct colors in conjunction with alphanumeric codes. For instance, gasoline might be represented by a circle, diesel by a square, and various blends by combinations or specific lettering. This visual cue is particularly important for drivers who may not be familiar with the specific terminology or chemical names of different fuels.

The introduction of the polttoainetunnus system aligns with broader European Union initiatives aimed at harmonizing fuel labeling for consumer safety and clarity across member states. While the specific visual representations might vary slightly between countries, the underlying principle of providing a clear and standardized fuel identification remains consistent. This system benefits both consumers by reducing confusion and the risk of errors, and fuel providers by promoting efficient and safe refueling operations.
