What are the effects of thin engine oil on the engine?

[LaJonathan]

Thinning engine oil can lead to excessively low oil pressure and cause semi-dry or dry friction between various mating components. Below is relevant information about engines: 1. Introduction: An engine is a machine capable of converting non-mechanical energy into mechanical energy. 2. Classification: Includes internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. 3. External combustion engines: These refer to engines where fuel is burned outside the engine. 4. Internal combustion engines: Internal combustion engines, or reciprocating piston engines, differ most from external combustion engines in that fuel is burned inside them. There are many types of internal combustion engines, with common gasoline and diesel engines being typical examples.
