Measuring the water temperature is one thing, ....measuring the oil is another thing - wouldn't the oil temp give you a better idea of the engine temperature??? Maybe the water stay relatively the same when the oil can spike up more rapidly - and the water is more diffused whereas the oil is not as diffused - I mean there isn't any oil circulating up to your radiator...
