Temperature gauge never moves above 25%

I purchased this 1996 Integra sedan in August of 2017, and almost immediately drove it from Seattle, WA to San Diego, CA and then Black Rock City, NV before driving back to Seattle. The temperature gauge never moved above about 1/4. Like in 110 degrees and driving the car nonstop for 20 hours and it wouldn't even move halfway.

I didn't trust it was accurate but I never had to add coolant or pullover from overheating so I just ignored it. Then I was trying to figure out why I was only getting 20 MPG, and not 30. I was advised to replace my thermostat, and that it was possibly stuck in the open position. I just completed that installation and I'm still only seeing the temperature gauge at 1/4 once the car warms up.

I figure two possibilities. The actual gauge is malfunctioning or the sensor near the thermostat is. Any advice?

Wouldn't bother me if the gauge was steady, functional and registering below mid-point. However, since you are looking for a culprit to why the car is getting less than desired gas mileage you may want to look elsewhere. The coolant temperature sensor that sends a signal to your OEM cluster would have nothing to do with it. There is a separate coolant temperature sensor that sends signal to the ECU. If anything, that would be the sensor that could potentially cause bad gas mileage if it tells the ECU that the car hasn't reached it's normal engine temperature. If it was my car, I'd first start with a tune-up (spark plugs, distributor cap and rotor, air filter etc.).
