Diesel costs more then gasoline because it uses more petroleum to make it. Also, diesel costs more then gasoline because it has about 20% more energy then the same amount of gasoline.

Does it cost more to produce diesel fuel than regular gasoline?
I'm going to go with "No" as gasoline requires more refining than diesel does.
Do diesel cars generally cost more than gasoline engine cars?
Diesel cars do tend to cost more in general than gasoline engine cars. The claim on this is that it is more expensive to create and manufacture these vehicles, and due the fact that diesel vehicles are more fuel efficient.
Why diesel pieces are more than gasoline prices?
diesel is now a lot more expensive because there are more and more diesel cars so they can now make even more money just by raising the cost of the diesel
Which engine is more efficient diesel engine or gasoline engine?
Diesel engines are more efficient than gasoline engines.
Is gasoline volatile?
Gasoline is more volatile than diesel.
Why does diesel cost more than gas?
It's a supply and demand issue. Demand for gasoline is much greater than that for Diesel. Therefore, the supply of Diesel is less which drives up the price.
Are diesel cars more efficient than normal cars?
Because of a diesel engines high compression ratio, it will always be more efficient than an equivalent gasoline engine. However, this higher compression ratio requires a heavier, more expensive engine which isn't able to reach as high an RPM as a gasoline engine. It is for these reasons that despite their higher efficiencies, diesel engines are less popular than their lighter, less expensive gasoline equivalents. Diesel cars will provide you with a higher MPG rating compared to a similar gasoline powered engine. The price for diesel fuel is generally higher than the cost of unleaded gasoline.
What has more fuel energy petrol or diesel?
Gasoline has more energy per lb than Diesel.
Does ethanol fuel decrease fuel economy?
Here's the thing: Ethanol has less energy per gallon than gasoline and diesel, so for a given power output an engine will use more ethanol than it would have used diesel or gasoline. Miles per gallon will be poorer. But that's not the whole story. Ethanol - being considered more eco-friendly - is often a lot less expensive than diesel and gasoline. So even if you're using more of it, the cost-per-mile can be lower than for gasoline or diesel.
Why does a diesel engine develop more torque than a gasoline engine of equivalent displacement?
Diesel engine runs at a higher compression ratio than a gasoline engine. A typical diesel engine may also use a longer stroke and smaller bore than a gasoline engine. Diesel fuel has a higher energy density than gasoline.
Which is more powerful petrol or diesel engine?
Normally Diesel engines produce more torque than gasoline engines but less horsepower. Gasoline engines rev up quicker and produce higher horsepower at higher rpms. Diesel engines develop their higher torque at lower rpms which allows a diesel to carry a heavier load.
Are diesel engines more reliable than gasoline engines?
Yes, diesel engine will last much longer than gasoline engines. They are built much stronger but are also more expensive to build.
