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
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
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
or
―D―Y (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
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
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 contain 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.
