Transmission oil

Good day 2005 model 1.6 hdi I have 307 vehicles at 212000 km. I want to change the gearbox oil. What would be your advice? Vehicle Manual

I would recommend @ akk0212 hocam mobil 75W80 transmission oil.

manual 2005 model 307 1.4hdi manual gearbox oil change of my manual vehicle ... I said why I have not changed so far ... oily 75w 90 ... the oil that comes out is officially oily water ... you can see the filling area after removing the hair under the battery, you can empty the drain without removing the crankcase protection ...

I gave 2 mobile 75w 80 spars, I write the result here when the oil changes

yesterday mobile 75w 2 lt gearbox oil reached my hand, I changed it, the oil was not so old, I guess its former owner has changed before, I put 2 liters under the battery.

If the oil is not as thick as the engine oil, if the teacher is old, then the color tone changes when the trouble occurs in the gearbox. Again, there will be a little relief in the chassis.

Meanwhile, the gears are softened compared to the past

How many km should this oil change?
