Stellantis Light Duty Diesel Powertrains Now All 'Cooking Oil' Compatible

Stellantis says its latest range of diesel powertrains for passenger cars and light-duty commercial vehicles are fully compatible with ‘green diesel’ that can cut fleet CO2 emissions up to 90%.

Diesel fuel has only recently been overtaken in terms of CO2 emissions by the very latest gas-hybrid powertrains, so hydrotreated vegetable oil (HVO), made from renewable raw materials such as used vegetable oils, animal fats and waste cooking oils, will greatly enhance the attraction of the powertrains for ecologically focused businesses.

That said, the clean-air zones in some parts of Europe, such as central London’s Ultra Low Emissions Zone, are more focused on airborne particulates than CO2 emissions and would not exempt green-diesel-powered vehicles from daily charges if lower than the Euro 6 standard.

The hydrogenation process used to produce HVO results in a cleaner, sulfur-free fuel with significantly reduced levels of aromatic compounds and pollutants, making it a powerful argument for fleet managers to cut their companies’ overall CO2 emissions quickly and cost-effectively.

This green diesel is also validated for use in many existing Stellantis vehicles with Euro 5 and Euro 6 engines marked with “XTL” on their fuel filler neck. Additionally, certain non-XTL Euro 6 Diesel vehicles are compatible with HVO when equipped with engines: 1.3 MultiJet, 1.6 MultiJet, 2.0 MultiJet, 2.2 MultiJet, New 2.2 MultiJet 4.0, 3.0 V-6 MultiJet and 2.3 MultiJet (F1A - Fiat Ducato).

Stellantis says that by promoting the use of green diesel, it hopes to meet its customers' environmental ambitions in the drive to slow climate change.
