What is most viscous olive oil or cooking oil?

Olive oil is more viscous than cooking oil. Viscosity is a measure of a fluid's resistance to flow. The higher the viscosity, the thicker the fluid. Olive oil has a higher viscosity than cooking oil because it contains more fatty acids. Fatty acids are long, chain molecules that can tangle with each other, making the oil thicker. Cooking oil, on the other hand, contains more saturated fats, which are shorter chain molecules that don't tangle with each other as easily. As a result, cooking oil is thinner than olive oil.
