Thanks for the info.
I emailed Valvoine, Pennzoil, Amsoil and Mag1(Supertech). Valvoine said they had nothing compatible, Pennzoil said to call them, didn't hear back from Amsoil and Mag 1 said thier(super tech) gear oil is fine to use.
I had get it working today so I went with SuperTech 85w140 mineral. I found two manuals on line for the same saw from two different manufacturers. One recomended "90wt gear oil" and the other recomended "140wt gear oil" so that is why I just went with the ST85w140. That and they said it was fine and it says on the bottle it is fine copper and bronzed bearings. $4ish a quart is nice as well.
I had Pennzoil 80w90 marine Gl-5 in the sump when I opened it to show friend the gear becasue his gear stripped and thier was quite a bit bronze in the sump considering I just changed it last year. I'm sure it had never been done in the 20 plus years of it's life and I don't recall seeing much metal in the sump after dumping the origional fill. So I didn't bother to call Pennzoil.
I'll check the ST soon to see how it is doing. After about an hour of cutting steel tonight the gear box was not warm to the touch. It never really got that warm the the Pen 80w90 either though. I have it set for about 250rpm IIRCC.
