The target of the European Union (EU) from the 1990s has been to reduce the level of greenhouse gas (GHG) in the climate by 40 % by 2030 [1]. Currently the transport sector is one of the biggest greenhouse gas emission producer in the EU [2]. Drop-in biofuels can contribute to the reduction of GHG emissions in the transport sector. Diesel R33, a newly developed biofuel enables sustainable mobility fulfilling the European diesel fuel specification and reduces the GHG emissions by about 18.2 % against fossil diesel fuel. Diesel R33 is made of 7 % used cooking oil methyl ester, 26 % hydrotreated vegetable oil (HVO) and 67 % high quality diesel fuel. HVO was produced from rapeseed and palm oil. This new biofuel was tested in a fleet of 280 vehicles (passenger cars, light duty vehicles, off-road vehicles and urban buses) covering all emission classes. The impact of the new fuel on the vehicles, their emissions and the engine oil aging was investigated.
