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.

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.
Which is more efficient a petrol engine or a diesel engine?
It will depend upon the conditions. Under normal operating conditions a diesel engine is more efficient than a petrol engine.
What is more efficient diesel or petrol car?
diesel is more efficient
What is more efficient the gasoline engine or diesel engine?
The diesel is more efficient but more expensive to build.
Are diesel pickup trucks 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.
Which engine is more efficient diesel engine or gasoline engine?
Diesel engines are more efficient than gasoline engines.
Is diesel more efficient than regular gas?
Diesel takes longer to burn than gas so, accordingly diesel is more fuel efficient.
Does petrol or diesel cost more?
diesel is usually more expensive but diesel cars usually have more mpg than petrol cars
Which is more efficient otto engine or diesel engine?
diesel cycle
How do diesel cars run differently than other types of cars?
They actually run very similiarly, with the main difference being the process of which injection of the fuel is put into the engine. In this way Diesel fuel tends to be more efficient and works better with less.
Is Freightliner the most fuel efficient brand of semi truck?
There hasn't really been a brand of semi trucks recognized as the most fuel efficient. Since they run on diesel a more efficient fuel, semi trucks already are more fuel efficient than cars in terms of size and power.
What is the advantage of diesel generators over regular gas?
Diesel generators are more energy efficient, they are more durable and require less maintenance, have a longer life span, and while the cost for diesel is generally higher than gas it costs less to operate a diesel generator because of the fuel efficiency. Just like diesel cars versus gas cars, diesel will last longer. Diesel fuel is a cheaper longer lasting alternative to regualr unleaded gasoline.
