What temp range does your car run at? My thermostat opens up at 176F and go up to 215F if I'm staying still. But generally when I'm driving it's under 185F and lower on freeways. I believe I may have a lower temp tstat then what is specified. Spec is 95C/203F mine seems to be 80C/176F. Anyone know anything about this? I'm thinking I should change it to the 95C to improve mileage? And possibly put the car into normal mode as the correct temp range has been reached?
