Pressure fluctuations vs Temperature

How do pressure fluctuations in a fluid flowing through a complicated pipe system (such as an engine lubrication system) affect its temperature?

Does the net fluid temperature increase with increase in the magnitude of pressure fluctuations?

Or does it decrease?

Thanks in advance.

Any fluid flow disruption results in a decrease in flow rate with an accompanying increase in fluid temperature due to friction.

That should hold true for any type of flow - laminar or turbulent - correct?
