This results in lower operating temperatures- oil and coolant- for more most driving conditions.
I'm no expert, either.

Yes, with the lower temp thermo it opens at a lower temp... but it keeps getting hotter until it reaches operating temperature. The low temp thermo does not cause the engine to run cooler.

So "This results in lower operating temperatures" is incorrect.

I installed the low temp thermo and my operating temps have remained unchanged.
