The left column is mislabeled as Motorcraft when it's actually Supertech Conventional 5w-30. The right column is properly labeled.
The oil was in service for approximately 4.5 months. No oil was added during the OCI.
Comparing the two, it appears the Supertech maintained viscosity much better than Motorcraft.
