Water temp gauge moving more than a 1mm or two when hot indicates a thermostat stuck in the open position.
When you changed it did you flush out the head, block, heater, hoses and radiator with a hose?
Is the water rusty? Did you use antifreeze?
When you removed the two oil filters, was the filters full of oil?
If not, the pump/bearings are worn and air is entering the system when stopped.
When you remove a filter or drain the sump air enters the system and what the manufacturer's aren't telling you is that you should then disconnect the dizzy or coil and crank the motor 1st to pump out all the air before starting (race teams do this every time they start a cold motor)
The oil light is connected to a pressure switch, what the light was telling you is that you were trying to drive with a system full of air - not good
