Is it bad to use the exhaust brake?
The answer is yes – exhaust brake is not harmful to the engine at all. It is even recommended for truckers to have an exhaust brake. Mostly because trucks are heavy and need a lot of stopping power to make a full stop – especially during downhill. via
Does exhaust brake hurt fuel mileage?
When you use an exhaust brake, the exhaust is blocked and builds up in the engine. This slows the vehicle but also cools the glow plugs in a diesel engine. When the plugs cool down, they do not burn fuel as efficiently. This does cause a mild decrease in fuel efficiency. via
What does diesel exhaust brake do?
Diesel exhaust braking works by using the power of the engine itself to slow a heavy vehicle. When the exhaust braking is activated, exhaust is forced back into the engine, which causes the engine to run more slowly, or even reverse itself. via
What is an engine exhaust brake?
An exhaust brake is a means of slowing a diesel engine by closing off the exhaust path from the engine, causing the exhaust gases to be compressed in the exhaust manifold, and in the cylinder. Since the exhaust is being compressed, and there is no fuel being applied, the engine slows down the vehicle. via

Which fuel is better for the environment?
Diesel engines get better fuel economy than gasoline engines. Diesel and diesel engines produce fewer and less toxic emissions than gasoline and gasoline engines. They are safer for the environment. via
Why do diesels need Jake brakes?
"Jake Brake", or "compression release brake", is a component installed on diesel engines that slows the vehicle without the driver having to apply the service (foot) brakes. The Jake Brake releases compressed air from the cylinder, slowing the vehicle by absorbing the engine's power. via
