Ahh, I had to click on "View.. Header and Footer" to see it. My guess is that is a MS Word "header" on all their MSDS documents that were transferred to a new format, and does not necessarily reflect when the contents of the MSDS were changed (although it could reflect a content change).
Like I said, the specs in an MSDS are only related to hazardous chemical reporting requirements and may not be accurate beyond that. For example, the flash point is listed as >200C in the MSDS, and 230C in the Product Data Sheet.
At best, you might say there is a discrepancy between the Product Data Sheet and the MSDS, but we cannot say for certain that the MSDS is the "latest" or most accurate document.
I would send an email or call Mobil if you want to know which one is correct.
