Diesel takes longer to burn than gas so, accordingly diesel is more fuel efficient.
Yes a diesel pickup truck will be more fuel efficient than those that run on normal fuel. Diesel is designed to run longer than the regular fuel however it comes at a higher cost.
Diesel engines are more efficient than gasoline engines.
Diesel engines are more efficient than gasoline because chambers are different. A diesel engine has better gas mileage.
It will depend upon the conditions. Under normal operating conditions a diesel engine is more efficient than a petrol engine.
Diesel engines are more efficient. They get better mileage, produce more torque, and last much longer than a gasoline engine. They are also more expensive to build.
Diesel engines are more efficient and do use less fuel, but they do not cost less than a petrol engine, they cost more. Diesel fuel also costs more. A diesel engine will however last longer.
yes
I'm going to go with "No" as gasoline requires more refining than diesel does.
No, it's actually less efficent.
In general, yes. The diesel engine cycle utilizes much higher compression than a gas engine. And the higher the compression, the more "efficient" the engine- everything else being equal. Also, diesel has more energy (btu) per gallon that gasoline, so you win on two fronts.
usualy more efficient unless you use them more
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.
