Can I read Viscosity of 20W-50 Motor Oils on EtoBox?

Viscosity of 20W-50 Motor Oils by Mark Newman is a document available to read on EtoBox.

What is Viscosity of 20W-50 Motor Oils about?

The document summarizes an experiment to determine the viscosity of three motor oils (Castrol GTX, Esso Racing, and Shell Helix) at room temperature using the falling sphere method. The viscosities measured were 0.0309 kgm-1s-1 for Castrol GTX, 0.0277 kgm-1s-1 for Esso Racing, and 0.0268 kgm-1s-1 for Shell Helix. The document discusses the importance of knowing oil viscosity at different temperatures for engine design and performance. Sources of error and ways to improve the experiment are also outlined.
