Power and lubricant additive concentrates containing at least one anthrachinone derivative as a marking substance

Abstract

The invention relates to fuel and lubricant additive concentrates which comprise at least one anthraquinone derivative as a marker, to the use of such concentrates for additizing mineral oils and also for mineral oils which comprise such concentrates.
