The most common and most likely cause for the engine to not get to operating temperature is commonly cause by the thermostat stuck in the open position or is broken. The thermostat stuck in the open position will cause the heater to not get hot and the engine to run too cold causing loss of fuel mileage and can even lead to carbon build up and running issues in the engine. Have a mechanic like one from YourMechanic test and replace thermostat.
