Is the airspace in quart bottles of oil filled with inert gas to prevent oxidation before it get put in your engine?
I'm doubtful for quart bottles, you can crack the top and let air in/out, but for the 5 quarts jugs that I've bought, they had foil sealed tops.
I'm asking because a PP rebate I'm doing requires UPC codes or bottle rings (didn't buy a case, bought 6 individual quart bottles, so I have to do rings). I'm seriously debating whether I should cut the rings off and not crack the bottles open, I'm not using that oil right away, and want to minimize oxidation of the oil.
Thanks!
