Chemical compounds, having a melting point between 70.degree. C. and 130.degree. C. and soluble in hydrocarbons, are used as solid carriers in order to dose conveniently additives for fuels for internal combustion engines. The compounds are selected from the group consisting of alkyl-substituted phenols, aromatic carbonates, alkyl-substituted pyrocatechols, polymers of alkyl-substituted 1,2-dihydroquinoline.

Chemical compounds to be used as solid carriers for fuel additives

Dispersing additives for lubricating fluids are disclosed, which contain the oxazoline function and are prepared by reacting amino alcohols with mono or bicarboxylic linear or branched chain aliphatic acids having from 2 to 51 carbon atoms. These additives are characterized by a very high dispersing power which makes them particularly suitable for engines used in stop-and-go service.
