ABSTRACT ADDITIVE CONCENTRATES The invention provides an additive concentrate comprising an inert carrier fluid and from 10 to 80%w, based on the total concentrate, of a compound of the general formula Image (I) in which R1 and R2 each represent a hydrogen atom, or together represent a carbon-carbon single bond; each of R4 and R5 independently represents a hydrogen atom, or a C1-C20 alkyl or phenyl group, each of which may be optionally substituted; R6 represents a hydrogen atom, or a C1-C20 alkyl or phenyl group, each of which may be optionally substituted and R7 represents a group -CH2-NHR8 in which R8 represents an optionally substituted alkyl group, or a group -COX wherein X represents an optionally substituted alkoxy group or -NHR8 where R8 is as defined above; or R6 and R7 together represent a group Image , Image , Image where R8 is as defined above; x is 1 to 6, and each R3 independently represents an optionally substituted alkyl or alkenyl group or a group of formula Image (II), Image (IIIA) or Image (IIIB) wherein m is in the range 0 to 25, n is in the range 1 to 20, each R9 independently represents a hydrogen atom or a methyl or ethyl group, D is derived from a saturated or unsaturated hydrocarbon containing from 20 to 500 carbon atoms, and Y represents a group of formula Image (IV) in which R1, R2, R4, R5 and R6 are as defined above; x' is 0 to 5; R3' is as defined for R3 other than a group of formula II, IIIA or IIIB, R7' represents a group R7 as defined above or a group -CHO or -COOH, or R6 and R7' together represent a group Image , Image , Image or Image where R8 is as defined above, each group R3 containing a total of up to 550 carbon atoms, with the proviso that up to a maximum of 3 R3 groups can each simultaneously contains a total of greater than 40 carbon atoms; lubricating oil and fuel compositions containing the formula I compounds; and the use of the formula I compounds as dispersant additives.
