- the mixture After conditioning, the mixture is allowed to cool for one hour at room temperature. Then 500 ml of diesel fuel (test oil 1) is added and mixed well. After two hours of standing, the mixture is visually assessed for possible excretions, turbidity, insoluble components, etc., which give indications of oxidative changes (visual assessment). Then it is filtered through a 0.8 ⁇ m filter at a pressure difference of 800 mbar. The total amount must be filterable within 2 minutes, otherwise the volume filtered after 2 minutes is noted.
