Cloud point: the low temperature at which the wax in diesel begins to turn cloudy as it solidifies. This solidification of the wax thickens the oil, resulting in the fuel clogging the fuel filters and fuel injectors and fuel additive injectors in vehicle engines.
CFFP - Cold filter plugging point: the minimum temperature at which the fuel can still flow through a filter
FAME (Fatty Acid Methyl Esters) content of the bio-part
