The innovative in laboratory tested RAVENOL EFE 0W-16 is the worldwide first motor oil with license approval from API with its specification API SN and viscosity SAE 0W-16 – so it bears the title World's First. We tested the fuel usage and stability properties of the engine oil RAVENOL EFE 0W-16 compared with a standard SAE 5W-30 engine oil with the classification ACEA C3. The research results verify a reduction of fuel consumption and an extension of engine life.

The test is performed on Toyota Aygo engine with the motor ID 1KR-FE. This engine is not only used in Toyota Aygo, but also in vehicles like Toyota Passo, Daihatsu Boon, Citroën C1, Peugeot 107, Toyota Vitz, Toyota Yaris (2005–), Toyota Belta (2006-2012), Toyota iQ, Daihatsu Cuore L276 (09.2007-), Daihatsu Sirion M300 Subaru Justy (2008-), Toyota Wigo (2014-), Daihatsu Xenia (2016)
