Diesel Engines

Diesel engines are used in GMC vehicles to lower fuel costs and increase the fuel efficiency of a vehicle. Diesel engines offer improved fuel economy compared to gasoline engines due to their higher compression ratio. This means that diesel fuel provides greater energy for each gallon of fuel used, which means more miles per gallon.

Additionally, diesel engines are very reliable and seldom require costly repairs, thus saving owners on costly vehicle repairs. Finally, diesel fuels burn more completely and are cleaner than gasoline, releasing fewer emissions into the air, which in turn helps to reduce health risks and keep our environment clean.

Trim Levels and Features

By exploring trim levels and features available with GMC trucks, you can save money on fuel. GMC Truck Miles per Gallon averages are often higher than the national average due to lightweight design and efficient engineering. Higher MPG allows drivers to do more with their vehicles on less fuel.

Features such as an EcoTec3 engine, Duramax turbo-diesel engine, and Active Fuel Management are all designed to ensure optimal fuel efficiency. Additionally, the GMC Sierra 1500 Hybrid is a perfect example of a fuel-efficient vehicle.

GMC regularly adds features such as Auto Stop/Start technology, eAssist technology, and lightweight composites to ensure optimal fuel efficiency, which keeps your money in the bank while you enjoy your GMC truck.


When it comes to saving money on gas in a GMC Truck, aerodynamics is an important consideration. By optimizing the exterior body of a truck to reduce air resistance, the engine can move more efficiently and use less fuel. Quality aerodynamic modifications can increase the GMC truck’s miles per gallon (MPG) rating by 10-20%.

Simple changes such as tape or plastic sheeting on windows, grille blockers, and adding a bed cover can help reduce drags. More extensive changes to the truck can dramatically improve a vehicle’s MPG, such as:

  • wheel covers
  • bug deflectors
  • air dams
  • a complete change in the body style

When coupled with improved mechanical maintenance and driving habits, these modifications can help decrease the amount of fuel used and save money for the owner.
