[Mgs] Transmission Oil

[PaulHunt73]

In fact the older oils have eventually reduced their ZDDP, even products 
like GTX and Diesel grades, but still have more than modern formulations. 
There are specialist oils with higher levels of 1000 to 1200ppm for 
classics, but as said it's not needed for the gearbox.
