Conversely, putting 4 stroke oil into a two-stroke engine would prevent the fuel from combusting entirely.

Viscosity refers to the oil's resistance to flow, and it is usually expressed in a format such as 10W-30 or 15W-50. Detergents keep the engine clean by preventing sludge and varnish from building up on vital components.
