Gas vs diesel trucks: Which one gets more MPG?

As a GMC truck dealer in St. Albert, we're often asked which truck offers more MPG (miles per gallon) - gas or diesel? Diesel engines are rated about 25% more fuel-efficient than similar-sized gas engines. However, your fuel economy also depends on what you use your diesel truck for.

Let's take a closer look at why diesel trucks get more MPG and what this means for fuel-efficiency.

Why does a diesel truck get more mileage than gas engines?

Diesel fuel contains roughly 10-15% more energy than gasoline, which means that you would need less diesel to achieve an equal amount of power with a gas engine. Diesel engines are more efficient because diesel is more slow-burning and complete burning compared to gas. Diesel also offers more torque, which allows for better acceleration and less fuel used.

Diesel engines are built with a more robust internal system to handle the higher compassion ratio of diesel fuel. A stronger engine allows diesel trucks to work harder for more extended periods, making them durable and ideal for heavy-duty use.

Are diesel trucks more fuel-efficient?

Diesel trucks are typically an ideal choice for drivers who mostly use their vehicle for highway driving. Diesel engines return a higher MPG when heavily loaded. In city driving, the benefits of a diesel truck decreases.

Simply put, if a heavy-duty pickup truck is needed for extensive daily driving, a diesel engine saves money on fuel. If you're mainly using your vehicle for city driving and hauling small loads, the advantages of a diesel truck over a gas truck are slight.
