Abstract

This paper summarizes the published information on the relationship between oil viscosity and engine performance that may be of use in developing a new engine oil viscosity classification system. The specific engine performance factors and associated variables considered are wear, oil consumption, fuel economy, hot starting, cold starting, low temperature pumpability, noise, and shear stability.
