Hot oil massage
Article Abstract:
High temperatures within the engine reduces the viscosity of lubricating oils making them less efficient in areas where they are needed. Multi-grade oils have higher viscosity indices because of additive chemistry. This increases the viscosity of oils and makes them more efficient lubricants.

Article Abstract:
The viscosity of a motorcycle's lubricating oil sweeps it into the crankshaft and enables the bearing to carry a load of several thousands pounds per sq in. Computer modeling of oil shows that the apparent viscosity increases under pressure.

Fighting friction
Article Abstract:
Friction loss in motorcycle engines is largely caused by piston and ring friction. Cylinder materials and types of lubricating oils are discussed in relation to friction reduction.
