The temperatures here in Queensland are classed sub tropical, but on average after ~ 2-3 minutes warmup in the garage, my coolant temp hits its normal running range (80 deg C) after approx 5-6 km of light 80 km/hr (50 mph) running.
So your 20 minutes of run time before the gauge gets to normal seems excessive.....
Obviously oil temps trail this by some margin.
Don't forget that these guages are notoriously innacurate though - the slow reaction could be caused by the 'stat or the guage.
I replaced my 75,000 km thermostat last year with the LN Eng low temp 'stat and noticed the initial temp rise from cold was quicker than the original unit.
