I want to change my gearbox and final drive oil but I'm not sure if I am buying the correct oil.  I can find 80W90 in GL-5 but nowhere on the bottle can I find anything referring to it as Hypoid use.  It says it is for high pressure use but I'm confused if it will actually mention Hypoid.  Help?

Had me going there for a minute - 'what I have put in mine?'.

Anyway, you'll probably find this helps:

Very Happy Hi !
Just a week ago I changed my gear- and finaldrive-oil. (K100RT, build 1987.)
Always used Putoline 80W-90 'heavy gear' API GL-5 (and never had any problem shifting; smooth as a baby's bum  Laughing)
Good luck and drive safe !
Jos

I use Mobil 1 and Guard Dog Moly.  It gets changed about once a year.  No troubles at all.

GL-5 is a hypoid oil so you're good to go with that 80W90.
The only other question is whether you use mineral, synthetic or a semi.
