I don't in any way claim to be an expert in oil, but it is my understanding
that there is still a significantly higher sulfer content in eastern oil.
For this reason eastern oil turns acidic faster as it ages, and becomes more
acidic than western oil. I know a few very well respected classic car
builders that won't use eastern oil in cars that don't see regular service
because of this. I would not be surprised if the "dirtier" eastern oils
have some differences during their service lives as well. Again, I have
been told, that there is legislation going on right now to force the eastern
oils to become cleaner, but that is the extent of what I know.
Like I said, this is all second hand, and may be old mechanics' tales but I
don't know.
