GC cause leaks?

[Frank D]

Didn't do a search to see if this was covered before but here goes. Did my first oil change with GC from my stash of 45 qts this past Saturday and noticed that even though all 45 qts were standing upright on the shelf in the garage, there is green oil leaking out of about half of those 45 qts. Are these just bad oil bottles or is this oil eating through the plastic bottles? If so, can this oil eat through engine seals?

i'm pretty sure the caps are defective or loose.

Normally I find the caps on GC not tightened very tight. So you may have some leakage during transport?
I seriously doubt the oil is oozing thru the bottle.
