Some thoughts on oil:
The oil companies don't need to worry about crude supply, they raise prices when it's low - to recover cost and maintain profits. They lower prices when it's abundant and still recover cost and maintain profits due to larger sales volume.
I shifted some retirement investments into energy companies (oil, coal, & ng) and energy services (drilling rigs, drilling ships and platforms, and tankers) to offset the cost of gasoline and diesel. With the recent discoveries off Brazil and in the Gulf of Mexico, the demand for drilling services will be a growth market for a while. Use the market for your own profit - get on board and reinvest the earnings, oil companies pay dividends.
There are around 100 regional blends of gasoline produced to meet the environmental regulatory demands of various state and local governments. What can be sold in one area is outlawed in others. This reduces nationwide supply and requires capital investment to modify refineries to produce the fuel used in a limited area. For example, California required the addition of MTBE and/or ethanol to reduce smog, this required a change to refineries to blend the gasoline adding cost. The requirement for Low Sulfur and Ultra Low Sulfur Diesel Fuel required process changes to the refineries and addition of lubricity and CETANE agents to the fuel - an investment that raised the cost of diesel above gasoline. The ULSDF has less caloric energy than the old #2 diesel and further exacerbates the problem with less mileage per gallon. One or two standard gasoline formulations would greatly decrease the cost of production and distribution - lowering the pump price.
The mandate of E-85 ethanol gasoline blends further increases costs, because ethanol production requires slightly more energy to distill than it produces on the road; E-85 blends also produces less mileage per gallon than regular gasoline (about 10%). Ethanol can not be shipped by pipeline, so its shipped by rail car and tanker truck, and blended just before distribution - adding to the cost. Use of food grains to produce ethanol raises food costs and is detrimental to the overall economy.
There is a growing body of evidence that oil is not a fossil fuel, but is a continually produced product of the earth's mantle. Read Black Gold Stranglehold: "The Myth of Scarcity and the Politics of Oil" by Jerome R. Corsi, Ph.D. and Craig R. Smith. Natural processes with in the earth's crust produce oil and gas due to biological chemical reaction, heat and pressure exclusive of dinosaurs and ancient forests (in other words oil is a natural biofuel being produced continually). Another recent study of Gulf oil deposits show no relationship to fossil sources, adding validity to the theory. Depleted oil wells are slowly refilling - confounding some experts. There are aromatic hydrocarbon clouds in interstellar space - and no dinosaurs ever walked there! Indeed there is a discussion that such hydrocarbon pools were incorporated into the Earth at its formation.
So - long post but I tend to rant.
