Compare the Mobil 1R VOA to the Mobil 1 SS 0-30 VOA and you do see a difference in TBN, SUS and Flash as well as big differences in the add pack, especially with regards to zinc (good bye API for M1R), calcium and boron. Perhaps the base oil is mighty similar on the PDSs because of an error on Mobil's web page?quote:

The only thing I've seen in M1R via VOA is a different additive package![]()
The "typical properties" listed on it's PDS Racing 0w-30 would suggest it has exactly the same base oil composition as the standard 0w-30.
Please enlighten me!![]()
