    Changed the oil. Oil was a bit grayish in colour. Drained some 20 litres and filled back 20 litres. Started the engine and the oil level went down remarkably and remained still a bit over the recommended level.

    Gray colour is a sign of some water in the system?

    Its only natural that you will get some condensation in a hot metal tank when the machine cools down, so water contamination is not unusual , but it depends on the system the machine uses. My old Fordson Major tractor hydraulic oil looks like custard

    Custard translates to Finnish as a type of sauce made of milk and eggs.

    There is some air space and when ever the temperature of the surfaces reaches dew point, moisture in the air condensates.
