Saudi Arabia, ExxonMobil, Warren Buffett: if you are an oil producer, retailer or investor, you have to be pleased with the recent jump in oil prices. It is, as Iago says, money in your pocket. More money for every barrel that you produce, sell and resell (at, of course, an even higher price). But you’re none of the above, you’re you, and each time you have to fill up that oversized tank with low-sulfer diesel, it feels that the noose closes a little more tightly.
