Thermostat normal or no?

[Lib88888]

Hi guys, my temp gauge rarely gets above 1/4, never seen it at half. My heaters work & blow hot air when needed, although on long drives the temp gets to 1/4 and then when I’m slowing down it soon goes back down.

Is this normal?
What effect is this having?

Thank you

No, you are running cold. It will reduce power and fuel economy and potentially slightly increase engine wear.
