Discussions and Author Closures from the Symposium Entitled, “The Relationship Between Engine Oil Viscosity and Engine Performance-Part V” [SAE SP-460][ASTM STP 621-S4]

This paper consists of the prepared discussions and author closures from the two SAE/ASTM viscosity related symposia held in 1979 (Part V). The first symposium was held in Detroit, Michigan as part of the February–March SAE Congress and Exposition meeting and the second symposium was held in Dearborn, Michigan during the June SAE Passenger Car Meeting.

The eight papers presented in these two symposia (Part V) were bound into a booklet along with four papers from the February, 1980 SAE/ASTM Viscosity Symposium (Part VI) held during the SAE Congress and Exposition meeting.

These discussions and author closures for Part V only provide a supplement to SAE SP-460 and ASTM STP-621-S4.
