Gearbox fluid

Even after car sale, I have material for few more posts :-)

Today my friend asked me about gearbox fluid.
You can refer to my old post about gearbox to find some information.

This manual gearbox is filled for life, as manufacture said. But I would change it anyway (if car was with me) at 90K anyway. Because synchronizer rings material wear and polluting oil, aging.

6A from picture above is a transmission oil. Comes in 1 and 2 liters plastic bottles.
VAG code is G 052 512 A2, cost about $20 for 1 liter. Previously was GCN 052 512 Z2 but was dropped at 2010-06-24.

It should be G50 SAE 75 W 90 synthetic oil.
