Picking wrong can sap power- forcing the engine to use too much effort to move the oil, and even destroy the engine- too thick will not allow oil to move correctly in the engine. Lubrication is more about maintaining the right thickness of fluid between the parts (which is pressure AND flow) than it is to just have static fluid at locations.

I agree! Read your owners manual for viscosity recomendations and only use an oil with a starburst or dexos symbol. These symbols have robust testing behind them that is recomended by the auto compaines.
