Is anyone surprised that Redline barely passed this test?

This test method predicts the high
temperature deposit‐forming tendencies of
an engine oil using the thermo‐oxidation
engine oil simulation test (TEOST). This
method can be used to screen oil samples or
as a quality assurance tool.

Motor oils can form deposits when exposed to increased heat, reducing efficiency and contributing to poor
overall performance. According to the ASTM, the TEOST test method “is designed to predict the high temperature
deposit forming tendencies of an engine oil. This test method can be used to screen oil samples or as a
quality assurance tool.”1 Given the number of vehicles now equipped with direct fuel injection, turbochargers
and other performance-enhancing technologies that increase heat, deposit control has taken on increased
importance. To meet the API SN Resource Conserving and ILSAC GF-5 motor oil specifications, a 5W-30
motor oil must limit total deposit formation to 30 mg or less.

Knowng Redline barely passed, would you still consider it in a turbo or DI engine?
