STP Engine Flush is designed to help neutralise harmful engine acids, un-stick internal engine components and prevent contamination of new oil by removing contaminants left behind by ordinary draining. This in turn helps to maintain the engine's performance.
STP Engine Flush dissolves harmful sludge and deposits left behind after the engine has been running. A build up can lead to a lack of performance from your engine and lead to further problems later on down the line.
