DIESEL FAQs

Why do diesel vehicles generally have better fuel economy than many gas-powered vehicles?

A diesel engine uses a leaner fuel-to-air mixture, resulting in lower fuel consumption, meaning you’re able to travel longer distances between fill-ups. Diesel engines also operate using compression combustion (versus ignition in a gas engine), yielding better low-speed torque, which can allow them to operate more efficiently – especially during highway driving.

Why is diesel a smart choice for trucks and SUVs?

Because diesel engines provide a lot of torque at a low rpm, especially for their size. Torque is the rotational force an engine produces to help you power up hills and haul boats and campers behind your vehicle. Plus, Duramax engines are known for their reliability and durability.

What about maintenance and reliability?

Maintenance requirements (oil, filter changes) for a diesel engine are about the same as for gas-powered vehicles. Duramax engines are known for their reliability, and come standard with a 5-year/60,000-mile limited warranty on 2.8L Turbo-Diesel engines, or a 5-year/100,000-mile limited warranty on 3.0L and 6.6L Turbo-Diesel engines.  

Diesels make a lot of torque, but they don’t seem to have the horsepower of gas engines. Isn’t that a problem for responsiveness and speed?

An engine with more torque will accelerate more quickly initially because it has greater sustained force. The trick is keeping the rpm within the right range to keep it in the peak power band. Chevrolet does this by pairing the Duramax 3.0L Turbo-Diesel with an advanced, smooth-shifting 10-speed automatic transmission, and the Duramax 6.6L Turbo-Diesel with a legendary Allison® transmission.

Have diesels really changed that much over the years? Are they still loud and exhaust-heavy engines?

Diesel engine technology has changed a lot over the years, erasing the preconceptions that they are loud and rough-riding. And the thoughtful design of the inline 6-cylinder engine offers a smooth, balanced ride.

DIESEL GLOSSARY

DIESEL ENGINE


An internal combustion engine invented by Rudolf Diesel that ignites fuel through mechanical compression rather than the spark ignition found in gasoline-powered engines.

DIESEL FUEL


A combustible liquid fuel offering more energy density than gasoline along with less volatility.

TURBO-DIESEL


A diesel equipped with a turbocharger that uses waste exhaust gas to drive a turbine that forces more air into the intake side of the engine, allowing a smaller engine to produce more power with greater efficiency.

EXHAUST BRAKE


Helps to slow a diesel vehicle by closing off the exhaust path from the engine, causing exhaust gases to be compressed in the exhaust manifold and cylinders.

DIESEL EXHAUST FLUID (DEF)


A solution that is injected into the exhaust system of diesel-powered vehicles.

TORQUE


A measurement of an engine’s rotational force that measures the amount of work an engine can exert.
