Diesel engines always maintain a 20-30% fuel mileage advantage.

While towing, a gasoline engine loses fuel mileage much quicker than a diesel.

Diesel engines use the more efficient direct fuel- injection method.

Diesel fuel has a higher energy density than gasoline.

A diesel engine reaches its peak torque and horsepower at lower rpm.

Higher torque and higher horsepower at lower rpm means that diesels are better for towing.

A diesel engine will likely produce at least twice the engine life of a gas engine.

Due to the high compression, diesel engines have to be built stronger and as a result, tend to last longer than gasoline engines.

Diesels have less finicky fuel and air mixture systems.

Diesel engines have less unburned fuel than gasoline engines.

They have less emissions than gasoline engines.

Have diesel particulate filters which are 99% efficient.

The only emission they emit is carbon dioxide and water.
