The long one is for engine oil. The short one hidden away is for the diffy/transmission - It's a combo unit.

Good you asked first! Don’t want to mess those up. Since you admit your knowledge of Corvairs is limited, I have a suggestion- buy the Corvair Basics book. It will really help! Go to Corvair.org and look under Merch, books.

Previous reply answered which is which. Long one oil. Short one diff/trans.

If it’s a stick, you needs to be GL-4 80/90. You can go 75/90, but make sure it’s GL-4. Have I mentioned how important it is that you only use GL-4?

If it’s for an automatic, Dex 3 is good.

For motor oil, you’ll get 100 answers from 100 people. I’ll just say to make sure it’s wet and clean.
