Fuel production efficiency
Does anyone know much oil is used to produce a gallon of gasoline? A gallon of diesel? And how much energy from other sources goes into their production?

Is this what you need.

That's a great site!
So 42 gallons of crude oil produce 19 gallons of gasoline plus 10 gallons of diesel. And since they are different fractions, then the amount of one can't be reduced in order to produce more of the other? Am I right? So why is diesel cheaper than gasoline in most parts of the world? Since there is almost twice as much gasoline "in" a barrel of crude than diesel, plus diesel is used in trucks, ships, etc., in much greater amounts than gasoline is used by cars, so there should be less diesel available than gas so it should cost more (by at least a factor of 2 or 3). Or maybe diesel is so much easier to produce, while gasoline is needed for other things? |

interesting stuff.
another note about diesel and gas, even though diesel claiming to use more... it can sit and vibrate on heavy duty applications with no loss, and HUGE work in comparison. a pinhole in a gas tank drops a car by tens of mpg, and odors everyone around it. It is kinda like the lose weight for efficency, all while not using enough resources to make a perfect boxer engine for the heavier car, for more passengers, and more chores, and comfort and durability by decades over the rest...one big puny mind we are owned by...called marketing. :rolleyes: woops. I started ranting. |
Most gasoline has been cracked from heavier fractions of the crude oil, or nudged into reduced volatility because it is one of the preferred standard products. If you start with tar sand or oil shale, you've put a lot of carbon in the air even before you fill your tank. If you don't care about cost, you can make gasoline from coal and water.

...just like nuclear reactions (bombs), making gasoline depends upon whether you build it UP (fusion) or break it DOWN (fission).
...there are MANY ways of making gasoline, some much less costly than others. |

The actual cost of the litre of gasoline or diesel you pour in your tank has little direct connection with the cost of getting into the pump. Here in Australia we pay around 52c per litre tax on a retail price of $1.25...about half in other words. Motorists world wide are the cash cow for many governments where as if they hit diesel with the same rate of tax they run up against their sponsors and supporters in the form of larger companies and organisations.

Right. Gas is only for small vehicles, so it could be viewed as a luxury, in a way. On the other hand, diesel is is needed for transport, so increasing its cost would cause prices to go up, increasing inflation, etc.
