VERVA ON - premium


Premium compression-ignition engine fuel, VERVA ON is produced form carefully selected hydrocarbon components, whose quality is ensured through continuous monitoring across the production process at the Płock Production Plant as well as across PKN ORLEN's entire logistics chain. The product complies with the stringent EU standards for “sulfur-free” fuels with a sulfur content of less than 10 mg/kg.

Marked with letters B, D or F respectively, the three grades of VERVA ON diesel oil have each different low-temperature properties (cold filter plugging point – CFPP) required for temperate climate fuels: 


  • ​Grade B VERVA ON diesel oil with a maximum CFPP of 0°C,
  • Grade D VERVA ON diesel oil with a maximum CFPP of -10°C,
  • Grade F VERVA ON diesel oil with a maximum CFPP of -20°C,


Different grades of temperate climate VERVA ON diesel oil 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 end of February.


To ensure smooth start and trouble-free operation of the engine at low temperatures, VERVA ON 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 PKN ORLEN to produce VERVA ON.

VERVA ON is dedicated in particular to passenger cars with modern common rail diesel engines. The increased cetane number of VERVA ON (from standard 51 to 55) improves performance characteristics of your vehicle, rendering its engine operation more dynamic, facilitating start-up, and lowering the engine operating temperature. An addition of dedicated lubricants reduces fuel consumption and enhances trouble-free performance of injection pumps. VERVA ON extends the engine's lifespan, increasing the mechanical durability of its components (cylinders, pistons, rings and valves).

Enhancing additives in VERVA ON serve as:


  • ​detergents helping keep the engine's air inlet and injection systems clean by removing sediments deposited in the engine when using fuels of unknown origin,
  • corrosion inhibitors protecting the engine against corrosive agents present in the fuel supply, combustion and exhaust systems, 
  • antioxidants preventing degradation of fuel and ensuring its high stability during storage. 



The latest generation VERVA ON has been created to allow your engine to run at its optimum performance in different weather conditions and under variable load. An increased content of a cleaning additive helps keep the engine's air inlet system dirt-free and remove sediments deposited previously when using fuels of unknown origin.

VERVA ON 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 oils - Requirements and test methods.
