ABSTRACT:
The present invention relates to the use of at least one heterocyclic compound of the formula (I)in which R is H or C1-C3-alkylas a frictional wear-reducing additive in fuel compositions; to corresponding additized fuel compositions and their preparation; and to additive concentrates which comprise such compounds.
