The Ekodiesel ULTRA diesel fuel is produced from carefully selected components, whose quality is ensured through continuous monitoring across all stages of production. The fuel contains a range of additives which prevent corrosion, water emulsification and foaming. Its production process ensures that Ekodiesel ULTRA remains resistant to microbial contamination and meets the lubricity and oxidation resistance requirements. In order to protect the environment, Ekodiesel ULTRA is guaranteed to have a sulfur content of less than 10 mg/kg, and its cetane number of more than 51 reduces fuel consumption and facilitates cold start.
Marked with letters B, D or F respectively, the three grades of Ekodiesel ULTRA have each different low-temperature properties (cold filter plugging point – CFPP) required for temperate climate fuels:
- Grade B Ekodiesel ULTRA with a maximum CFPP of 0°C,
- Grade D Ekodiesel ULTRA with a maximum CFPP of -10°C,
- Grade F Ekodiesel ULTRA with a maximum CFPP of -20°C,
Different Ekodiesel ULTRA grades should be used in different seasons in accordance with the following guidelines:
- grade B – in summer, from April 16th to September 30th,
- grade D – in transition periods, from March 1st to April 15th and from October 1st to November 15th,
- grade F – in winter, from November 16th to the end of February.
To ensure smooth start and trouble-free operation of the engine at low temperatures, Ekodiesel ULTRA made for winter and transition periods contains components modified in production process, depressing agents which change the structure of paraffin crystals to prevent filter plugging, and agents which disperse paraffin crystals.
No manganese-based metallic additives, including methylcyclopentadienyl manganese tricarbonyl (MMT), are used by ORLEN to produce Ekodiesel ULTRA.
Ekodiesel ULTRA complies with the Minister of Economy’s Regulation of October 9th 2015 on quality requirements for liquid fuels (Dz.U. of October 23rd 2015, item 1680), the Minister of Economy’s Regulation of October 9th 2015 on quality testing methods for liquid fuels (Dz.U. of October 23rd 2015, item 1679), and Polish standard PN-EN 590 Automotive fuels − Diesel fuels − Requirements and test methods.
