Abstract: The invention relates to the use of an effective quantity of borated compounds having the following general formula I: in which X is S or O, and R is a hydrocarbyl group containing at least 3 carbon atoms, in particular between 3 and 50 carbon atoms and preferably between 3 and 17 carbon atoms, as an additive improving the compatibility of a lubricating oil composition, comprising dispersants containing basic nitrogen atoms, with fluorocarbon elastomers. In a preferred fashion, the compound of genral formula I is borated glycerol monooleate and the concentraion of the compound of general formula I is such that the % Boron/% basic N ratio of the lubricating composition varies from 0.25 to 5.
