The quality of European diesel fuels is specified by the EN590 standard. While these specifications are not mandatory, they are observed by all fuel suppliers in Europe. It is intended for application in diesel engines. Diesel motor fuel quality meets the requirements of European Standard EN590.

For operation in the conditions of a temperate climate following marks of fuel diesel automobile, EN590 are offered:

1. Grade A – limiting filterability temperature +5;
2. Grade B – limiting filterability temperature 0;
3. Grade C – limiting filterability temperature –5 °C;
4. Grade D – limiting filterability temperature –10 °C;
5. Grade E – limiting filterability temperature –15 °C;
6. Grade F – limiting filterability temperature –20 °C.

The entire volume of produced diesel fuel quality meets the requirements for fuels for vehicles of Euro 4 and Euro 5. Low sulfur content reduces emissions of sulfur oxides into the atmosphere, which is especially important for inhabitants of big cities.

Many countries in Europe require diesel fuel to meet a specific class in winter. In Central and Western Europe the Winter Diesel must meet Class F conditions at least from the beginning of December to the end of February. During a transitional period (mostly October and April) a lower Class must be met. In the Scandinavian countries, the Winter Diesel must meet Class 2 conditions. Some mineral groups offer both types commonly known as Winter Diesel and Arctic Diesel.
