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.
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.
No, it's actually less efficent.
usualy more efficient unless you use them more
Diesel gas gives more mileage (miles per gallon) than regular gasoline. You must, of course, have a vehicle that has a diesel engine because diesel fuel cannot be used in an engine that runs on regular gas! Depending on local government taxation policies, in some countries diesel is cheaper to buy than regular gas whilst in other countries it is more expensive! Diesel fuel is thicker and "stickier" than regular gas so, if a vehicle's fuel system ever needs cleaning - fuel tank, fuel lines, fuel pumps and fuel injectors - it is a more difficult and expensive job to do on a diesel vehicle.
