Why did the olive oil not work completely in Oil?

Olive oil is not a good choice to use in an oil lamp because it does not burn cleanly and can produce a lot of soot. The wick of an oil lamp needs to be able to absorb the oil and draw it up to the flame, but olive oil is too thick and does not wick well. This can cause the oil to build up on the wick and eventually smother the flame. In addition, olive oil has a high smoke point, which means that it will start to smoke and produce soot before it reaches its burning point. This can make the oil lamp difficult to use and can also be a fire hazard.
