Yes. If the temperature changes enough, the viscosity of oil will change, too. Oil is designed to resist changes in viscosity with temperature changes, at least to a degree. But if the change (either hotter or colder) is extreme, then the viscocity will most certainly change. And, as you'd expect, as it gets hotter, the viscosity of oil decreases (it get thinner), and as it gets colder, the viscosity of oil increases (it gets thicker).

Does water or motor oil flow faster?
Water is faster by it's lower viscosity, though oil viscosity is more temperature dependent than that of water.
What does lube oil viscosity refer to?
The viscosity of a liquid is a measure of of "thick" the liquid is. E.g. Honey is very viscous, while water is not. In terms of motor oil, more viscous oil will thin out less at very high temperatures. Viscosity is represented by the number pair associated with the oil, such as 10/40, where 10 is the low temperature viscosity and 40 is the high temperature viscosity. (scale of 0-60, with 60 being the most viscous)
Hot oil room temperature oil room temperature water below room temperature oil Which is likely to have the lowest viscosity?
hot oil.
Does room temperature oil have a lower viscosity?
It isn't clear what you are comparing it to.
Why viscosity decreases with increase in temperature?
Temperature measures the speed of random thermal motion on the atomic and molecular level. When sub-microscopic particles are moving faster, the liquid as a whole will be more fluid and less viscous.
Motor oil is used to lubricate different parts of an engine The viscosity of oil changes as a motor runs or is turned off What external factor will most frequently change the viscosity of the motor?
decreased temperature
What external factor will most frequently change the viscosity of the motor oil?
decreased temperature
What does viscosity of motor oil?
hi brooklyn, the viscosity of motor oil is how quickly it flows
Does water or motor oil flow faster?
Water is faster by it's lower viscosity, though oil viscosity is more temperature dependent than that of water.
Why low viscosity motor oil used in the winter and high viscosity motor oil used in the summer?
Low viscosity oil flows easier when it is cold but become thinner when it is hot.

What refers to the tendency of oil to resist flowing?
Oil viscosity depends on it's temperature. The higher the oil temperature is, leads to higher viscosity and low flow resistance. Cold oil temperature leads to lower viscosity and higher flow resistance
What do you mean by SAE an motor oil?
SAE stands for Society of Automotive Engineers. Sae ratings pertain to the oils Viscosity. Viscosity is the flowability (resistance to flow) at a particular temperature.
What does a motor mechanic need to know about viscosity?
A mechanic needs to know which oil to select for the various moving parts of a car. The oil you use in the gear box is usually a higher viscosity than the oil used in the engine. The engine uses different viscosity oils depending on the seasonal temperature.
Does motor oil have greater viscosity than olive oil?
olive oil
What is easy to evaporate motor oil or water or petrol?
Petrol or gasoline will evaporate fastest. Water is next and motor oil would be the slowest. Factors include temperature, viscosity and surface tension of the liquid.
