I still have a small collection of can spouts - I'm not sure why I keep them.

I used the bagged gear oil to service the axles in my pickup this spring. I thought it was weird when I bought it, but it's easier to use than the bottles. I didn't even need the pump to to fill the front diff.

Regarding the additives separating - I seem to remember that being an issue with Kendall or Pennzoil back in the day. I think that was also the reason for GM backing away from 10w-40. I'm not aware that it's an issue with any of the modern, major synthetic engine oils.

I have seem reports that fluid separation is cause of the problems with the GM 8 speed truck transmission - supposedly a reformulated fluid fixes it. I think it was Ford that stopped supplying a transmission fluid in bulk because of separation - they were only supplying ATF to dealers in cases of quart bottles.

So lube separation is / has been a real issue. I'm just not aware that it's a current problem with motor oil. my practice is to let my bottles drain completely what I do a fill, so I can't say I'm going to worry about it.
