Hi,
need some gearbox Oil for my MK3 8v AGG.
Exactly what oil do I need to get?? I need someone to point out was viscosity I need etc (makes would be good too)
and I'm wanting to get the good stuff

lol
Also, I thought it had to be filled from the side of the box, but apparently there is a little pull plug on the top and you fill it up through there? Went to get some today and the oil bottles didn't come with a tube so filling on the top looks correct??? I dunno......
help please as always!
