    Abstract: An additive composition for fuels comprising at least one constituent (A) and at least one constituent (B), the said constituent (A) comprising at least one multinitrogen-containing compound of general formula (I): ##STR1## where R.sup.1 and R.sup.2, which are the same or different each represent a hydrocarbon group or a group of formula R.sup.5 --(--O--R.sup.6 --).sub.a --(--O--R.sup.7 --).sub.b --, R.sup.3 is a hydrocarbon group or a group of formula R.sup.8 --(--X--R.sup.9 --).sub.c --(--X--R.sup.1 O--).sub.d --(--X--R.sup.1 1--).sub.e -- in which X is selected from the groups --O-- and --NR.sup.1 2--, R.sup.5, R.sup.6, R.sup.7, R.sup.8, R.sup.9, R.sup.1 0 and R.sup.1 1 each represent a hydrocarbon group, a, d and e are each zero or a whole number, b and c are each a whole number, R.sup.4 and R.sup.1 2 each represent a hydrogen atom or a hydrocarbon group and n is a number from 0 to 20 and the said constituent (B) comprises at least one polyglycol which is soluble in the fuel in question. The additive composition may also contain a detergent-dispersant product. These compositions are useful as multipurpose additives for fuels used in internal combustion engines, in particular in spark ignition engines.
