Does oil affect plant growth?

I am doing a project testing dif. types of food that affect the growth of plants and was wondering if ';watering'; plants will oil with affect its growth and if so how much.Does oil affect plant growth?
I believe ';watering'; a plant with oil would eventually kill it. I may be mistaken, but the oil would most likely not feed the plant moisture, but clog up its ability to gain moisture or even the air/carbon dioxide it needs.Does oil affect plant growth?
oil will perfectly kill the plant.in most countries oils with sulpher are used as weedicides.this block the uptake of water and blocks the cell membrane pores.so the plants usualy cannot grow in areas where soil contiminated with oil.
Oil will definitely kill a plant. After all, a lot of herbicides are based on or use oil derivatives.
