Ok, that did not work but here is from an older post:
Front differential oil Oil in use Subaru gear oil Extra S 75W-90 (GL-5)
Oil amount: 1.4 liters
Drain plug is on bottom of CVT (T70 plug labeled 'diff oil'). Fill through charge pipe. Don't believe there is a dipstick. You pull the overflow drain plug (beside the main drain plug) to determine when full.
