In Germany, sufficient oxidation and cold stability is essential for the safe use of biodiesel (FAME). The additives used must not have any negative interactions with the FAME itself or the base diesel fuel and its additives. Only two antioxidants and one flow improver were able to pass the challenging no-harm tests in 2023 and be included on AQGM’s no-harm lists.
In this year’s test round, three additives were able to pass all the demanding tests. The antioxidants Spec-Aid BIO9401 and Spec-Aid BIO9402 (both VEOLIA Water Technologies and Solutions Belgium BV) and the flow improver Bio WinterFlowTM 902 (Innospec Ltd) were included in the respective no-harm lists.
