As others have said, there are too many variables. Unless you put a thermometer in your oil, you won't know the temperature - and neither would the stove. Any time you fry, you should use a cheap thermometer - same when working with candies. However most oils smoke in the upper 300 range, so if it smokes turn it down a notch and you are likely right around 350°F.
For example: suppose you put your stove on high and have oil in a pot. The oil will reach into the 400°F range. But now do the same thing with the same pot filled with water. The water will boil at ~212°F no matter how high you turn the stove to. So how will your stove know the difference?
