# At which temperature is the oil most viscous?

oil is most viscous at the lowest temperature, because as the temperature gets higher, the viscosity gets lower and such the flow rate decreases as well.

e.g- 19 degrees, 22 degrees, and 31 degrees C.

the most viscous is- 19 degrees C.

the least viscous is- 31 degrees C.

If you don't know one way or the other, that would be the way to bet.

However, it's possible to make motor oils of a blend of substances such that they don't substantially change viscosity as a function of temperature (over some specified range), and it's probably possible to make ones which are more viscous when hot.

Viscosity is a measurement to the oils resistance to flow. Therefore the temperature at which oil will still flow but has the greatest resistance is just above freezing temperature.

### What does 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)

### What is the effect of temperature on viscocity?

the colder most liquids get, the more viscous they get.

### What the most viscous liquid?

Some People might consider glass as fluid at room temperature... I believe it's one of the most viscous fluids..

### What is the different between 5w20 engine oil and 5w30 engine oil?

30 is a little more viscous (thicker) at operating temperature than 20.

### 5w20 oil vs 5w30 oil What is the difference?

Both behave the same when cold but the 5W30 is slightly more viscous at high (engine operating) temperature.

### Can viscous oil freeze?

Freezing oil will be extremely viscous. Oil does not freeze easily. The freezing point of oil is very low like -30oC.

### What is an example of viscous Friction?

oil in a car's engine reduces viscous friction and wear

### Discuss how effective a car suspension damper would be if the oil in the damper was replaced by oil that was much more viscous?

The effectiveness of a car suspension damper after exchanging the oil in the damper with oil that is much more viscous is increased. The viscous oil gives a smoother and a more powerful effect to the suspension damper.

### What is the definition of viscosity?

Viscosity is a fluid's resistance to flow. Fluids becomes less viscous as the liquid's temperature increases, becoming more viscous as the fluid gets cooler. A viscous fluid is sticky, thick and syrupy to a greater or lesser extent. Examples Treacle is quite viscous, but water is not. Hot engine oil is less viscous ('thinner') and runs more quickly and smoothly than cold engine oil.
