Motor oil and transmission oil:
Synthetic oil has a number of additives, and they do not all weigh the same. If the oil has been on the shelf for a long time (say 3 months), do some of the additives settle to the bottom? float to the top? so that the container needs to be shaken before use?
And what about the drums of motor oil at the dealership (and other shops) that sit for long periods - Do the ingredients separate so that you don't get an homogenized mixture of all the additives?
