All, I went to my local TSC, and several auto parts stores and can't find any SAE 90 gear oil. I just purchased an older Ber-Vac 60" snowblower and it says the gear oil needed is SAE 90. Can I use something different?

Usually you have some wiggle room for temperature variations, but your range is pretty narrow in winter.
75w-90; 80w-90 are very common & so long as theres adequate expansion room in the gearbox & mnfctr doesn't shun use, either should be fine if straight 90 is hard to find.

Thank you all for your help. Now for a followup question, how full do you fill the gearbox? I don't see a dip stick or window that shows how full it is. Attached is an image of the gearbox.
