Abstract
Carbodiimide for use as an additive in lubricants intended for drive device systems for improved elastomer compatibility The present invention relates to a lubricant composition intended for a drive system, comprising at least one or more base oils, at least one carbodiimide additive and at least one basic organic additive improving TBN; as well as a process for lubricating a drive system using such a lubricating composition. It also relates to the use of at least one carbodiimide additive in a lubricant composition intended for a drive system, to improve its compatibility with elastomers.
