Abstract

The invention relates to a method for validating engine oil (1) connected to: - a ventilation circuit (10) comprising a valve (11) configured to be in an open state and a closed state; - a heat transfer circuit (20) and a pump (22) configured to circulate a heat transfer fluid in the heat transfer circuit (20). The method comprises the following steps: - a step of starting the engine (1) at a predetermined engine speed; - steps of pumping the heat transfer fluid according to predetermined fluid flow rates by the pump (22) when the valve (11) is in the closed or open state; - a step of comparing a measured engine fouling level (1) after pumping the heat transfer fluid with a predetermined engine fouling level (1), so as to validate the engine oil (1).
