Out of curioisty as until I started paying attention to your posts a few months back I didn't realise there was a difference between gear oils and manual transmission oils, I thought GL-4 was for MT's and GL-5's were for transfer boxes and differentials. Why would Fuchs Sintofluid 75w80, a manual transmission fluid carry GL-5? I always assumed you needed the EP additives in order to have the GL-5 specification? I have considered using this oil as a one-size-fits-all in MT's, transfer boxes and differentials.

Agree and thanks for the clarification. I presume having an additional healthy dose of PAO makes it potentially the "la crème de la crème" :-)

You could ask Fuch's but I suspect their level and type of Anti-Wear additives qualifies it for GL-5 in testing. This raises a question as to what industry standards they tested this fluid to quality it as a GL-5. If you do contact Fuch's, ask them about this statement in their advertising:

Prevents reliably from wear, sludge formation,agglomeration and corrosion.
