What is the common interval in changing the oil in the gearbox?
Mine is making a 'singing' noise only in really hot weather just at the point between accellerating and decellerating. Has anyone had the same experience? And did an oil change solve the noise?
I presume it is time to change the oil, it has been 250.000 km when oil got in (at the factory).
I'm thinking of replacing it with Castrol Syntrax 75W90, a full syntetic. Any good?
