Sorry, for posting this here, but I have searched Google and various other sources to find out what weight gear oil goes in my '80 Corolla.

Any techs able to check alldata or mitchell real quick and tell me? I know it is a heavy-weight gear oil, but not sure exact weight. I do not have a shop manual for it, and the nearest library is over 20 miles away.

Thanks in advance.

 

alldata only goes back to 82 rwd corolla.. and that calls for 75w90 or 80w90 1.8 quarts
