I will say that just in case there was some differential oil making its way to the catch can, I had the inlet from the differential inserted into the bottom of the catch can so that fluid could return to the diff once pressure lessened.

It really doesn't do the differential any good if the gear oil is forced into the catch can while driving for long periods of time as the gear oil isn't where it needs to be to properly lubricate the critical areas of the differential. Once you stop the car and what fluid that didn't spew out of the catch can is drained back into the differential what good does that do, the differential is no longer in use. When you start driving the car again the fluid is again forced out of the differential and into the catch can again, plus you have the added issue of the loss of oil that had previously spewed out of the differential from the previous drive or drives. Not all of the people that drive these cars pay attention to what is going on with their cars And may be oblivious as to what is going on with them. From what I was told by the manufacturer of the differential is that it takes very little fluid loss to start damaging the differential, so now you have lost fluid and fluid in a can where it does not belong especially when driving. In short if your differential has a predetermined amount of gear oil that it requires for operation that oil belongs in a place where it does the most good not in a can on the shelf to be put in later.
