Mine stays at the first quarter, up from cold. I would add more coolant if the gauge is unstably going up and down at different speed.

I think you may have a slow to open or sticky thermostat if you feel nervous as your engine warms up, and the temperature needle climbs and climbs, and starts to smell like roast duck with penzoil au jus...
