Type of oil for the gearbox

Post by so.net@sfr.fr »

Hello everybody
I have to change the oil of my 245 Sport gearbox on my 323i / 1981
Do I buy 75/80 or 75/90 ? Half or fully synthetic?
Is there a specific brand to use ?
What do you think about "miracle products" for the gearboxes (Mecacyl, Mecatech etc...) ?
Thanks everybody.
Olivier.
