Yes, I agree that oil should be changed at 3K miles. And running a cooler engine keeps the oil fresher during that period. IE the viscosity will not break down as quickly in a 180 temp engine as in a 195 temp engine.
But conversely, be aware of running too cool. IE 160 thermostat may not let the engine get hot enough to flash off water buildup in the oil. This is a common problem in engines where the thermostat was removed. That is a really bad idea.
