Ralph;
The repair manual recommends any S.A.E. E.P. 90 Lubricant.
I'm sure a synthetic would fine.
The important thing is that you jack up the rear end or park the tractor on a hill so you can get a full 2 pints through the filler hole in the back of the differential.
On level ground this is not possible.

Subject: (ET) Oil
I am doing a frame up restoration of a E20 I just got from my cousin. It has been in a barn for the last 20 years. I was wondering what type oil is used in the transaxle. I was thinking a light weight synthetic oil would be less drain on the motor and batteries. Anybody tried this? Or what is normally used?
