I'm still on "viscoelasticity" of multi-grade oils and bearing deform. Would that be all multi-grade engine oils, or just the VII'd ones?
Bearing deform: Can automotive type plain bearings deform and return to their original shape for millions of cycles?
Skip the increased particle generation of mixed and boundary lubrication, and go to bearing fatigue and seizure:
With low viscosity engine oil, would an engine design that dissipated heat away from bearings be better than a design that insulated the bearings?
Dissipating heat away from a bearing would decrease oil temperature, and while doing so, increase friction. Especially during warm up.
The trend for smaller slower rpm engines and longer oil drain intervals:
Would matching the engine power output to the total swept bearing area be a solution instead of going in every direction all at once?
