Oil constantly smoking. What is happening?
I would suggest first heating the pan for the requisite time and the required heat depending on what you want to cook, then add the oil for only a few moments to heat it up. Then add any ingredients to the oil after its been in the pan for no more than 10-15 seconds. If you heat up a cold pan with oil in it, its much more likely for your oil to smoke since it has so much time to absorb heat.

Sometimes of course, you might want it to smoke, in which case, leave the oil in for longer.
