Could you tell me why oil cost $73 a barrel two years ago and a litre of gas was $1.06? A year later, the same litre of gas sold for $1.10, but a barrel of oil was $61. The difference was $12, but the price of gas at the pump stayed the same. Why did your profit margin go from 9 cents to 28 cents per litre in the same year?
