Crude oil is the oil from the well. Motor oil has been processed.
The motor oil must have certain properties, such as viscosity and density, and it can not contain any contaminants, such as sulfur.
Crude oil is unrefined oil, and it has a wide range of viscosities and densities, and may contain contaminants.
Gasoline is a refined product derived from crude oil. Crude oil is a natural resource extracted from the ground, while gasoline is a processed fuel used in vehicles. The main difference is that crude oil is the raw material, while gasoline is the end product after refining crude oil.

Oil is a general term that refers to any liquid that is not soluble in water. Crude oil, on the other hand, specifically refers to the unrefined petroleum that is extracted from the ground.
High milage motor oil has extra additives which help prevent oil leaks.
Crude oil is that oil that comes out of an oil well head (before it is refined). However, different oil wells produce different types of crude oil (some is thick and some is very runny)For commercial trading purposes, Brent Crude is a major classification of sweet light crude oil that serves as a major benchmark price for purchases of oil worldwide.
Gear oil is normally a much heavier oil.
Crankcase or motor oil is thicker than transmission oil. That's one difference, there may be more (other than color)
Viscosity and additives.
Heavy crude oil has a higher density and viscosity compared to light crude oil. Heavy crude oil also contains more impurities like sulfur and metals, which makes it more difficult and expensive to refine. Light crude oil is easier to extract, transport, and refine, making it more valuable in the market.
15 is thicker oil and for bigger engines.
Crude oil is obtained from between underground layers of sedimentary rocks.
Motor oil SJ is for cars made between 1996 and 2001. Motor oil SN has been in use for cars since 2011.
