I would go for the GL-4 oil as it is possible the GL-5 has some additives which will damage parts in the gearbox.

Dave - per the earlier threads on here, personally I would go for a fully synthetic Castrol Syntrans/Syntrax for the advantages that they offer; they are pricy mind.

EP90 is what is recommended in the manual, though they do say to go to for an 80W if the temps are cold (not likely to be an issue in Aus).

To be honest either of the oils that you have would probably be fine (I don't believe that the Haflinger transmission is affected by the additives in GL5).
