摘要：
A fuel oil comprising: A) a mineral oil having a cloud point of less than −8° C., a boiling range (90-20%) of less than 120° C. and a difference between CFPP and PP of less than 10° C., and B) one or more copolymers, wherein the copolymers comprise: a) bivalent structural unit (B1), wherein (B1) is a bivalent structural unit of formula (1) —CH2—CH2— (1) and b) one or more bivalent structural units (B2), wherein (B2) is either a bivalent structural unit of formula (2) —CH2—CR1R2— (2) in which R1 is hydrogen or methyl, R2 is COOR3, OR3 or OCOR3, and R3 is an alkyl radical having at least 4 and at most 30 carbon atoms, or (B2) is a bivalent structural unit of formula (2a) in which R3 is an alkyl radical having at least 4 and at most 30 carbon atoms.
