TLDR
In this article, a series of bench tests are conducted to investigate the frictional performance of flat piston ring prototype (PRP) with various pockets and the results show that the pocket area ratio and depth have a major influence on the tribological behavior and significant friction reduction can be achieved by using pockets with appropriate geometric parameters (AR=25, depth=5μm).About:

Fuel consumption and friction benefits of low viscosity engine oils for heavy duty applications
TL;DR: In this paper, a comparative fuel consumption test, where a low-viscosity engine oil (LVEO) performance is evaluated on an urban compressed natural gas buses fleet is portrayed, and friction performance of the same oils are studied on a Cameron-Plint tribometer, on an adapted twin disc tribometer to simulate journal bearing friction and on a Ball-on-disc rig, using real engine parts in the former and the same set of engine oils used during the fleet test.
