While cleaning out my storage room I found some older Mobil One bottles and would like to know if these would be OK ?? I know there are alot of folks that say the new SS formula is good, but how was the Advanced Formula SJ and the TRI-SYN SJ in comparison. I found 3 on-opened cases of each in 10w-30. How do these older formulas rate the the new SS formula ?? Will I still be able to run 5-6K intervals and be OK ?? Any feedback would be greatly appreciated, thanks.
