If you’ve been wondering, “Are Buicks good on gas?”, what the Buick gas mileage is for each SUV or Buick MPG, or what the Buick Envision gas tank capacity is, this guide will answer all those questions and more.
Buick Encore GX

Both the Buick Encore GX and Envista are Buick’s smaller SUV offerings. However, both are incredibly impressive for their size and more than hold their own versus larger SUVs on the market. The Buick Encore GX is a five-seater that somehow finds a happy medium between family-friendly and weekend getaway with luxury and refinement.
It is powered by a 1.3-liter ECOTEC, 3-cylinder turbocharged engine and a 9-speed automatic transmission. The Buick Encore GX achieves 155 horsepower, 174 pound-feet of torque, and can tow up to 1000 pounds. When it comes to the miles per gallon Buick Encore plans on 29 MPG for city driving, 31 MPG for highway driving, and 30 MPG combined.
Buick Envista

It’s hard to go wrong with the Buick Envista. A winner of the Strategic Vision 2024 Total Quality Award, the Buick Envista comfortably seats five passengers, has 42 cubic feet of maximum storage, an 11-inch digital entertainment system, and an optional head-up display (HUD) and sunroof. These features are perfectly encapsulated within a refined interior.
The engine is a 1.2-liter ECOTEC 3-cylinder turbocharged engine that generates 137 horsepower, 162 pound-feet of torque, and allows for a towing capacity of 1000 pounds. Paired with a 6-speed automatic transmission and front-wheel drive (FWD), the Buick Envista attains an EPA-estimated Buck MPG rating of 28 MPG in the city, 32 MPG on the highway, and 30 MPG combined.
Buick Envision

The Buick Envision represents a sizeable upgrade from both the Buick Encore and Buick Envista. This is perfectly defined by the ultra, cabin-wide 30-inch digital infotainment and navigation system, as well as an increase in overall storage space. However, it’s the introduction of the 2-liter, 4-cylinder ECOTEC turbocharged engine with its 9-speed automatic transmission that Coulter Camelback Buick GMC will surely appreciate.
This powertrain allows the Buick Envision to attain 228 horsepower and 258 pound-feet of torque while being able to tow an extra 500 pounds at 1,500 pounds overall. With its standard all-wheel-drive (AWD) powertrain, the Buick Envision attains 22 MPG for city driving, 28 MPG for highway driving, and an impressive 24 MPG combined.
Buick Enclave

Finally, we have the ultra-luxurious Buick Enclave. The only three-row SUV offered by Buick, the Enclave seats 7 passengers and has the largest interior and overall storage capacity of any of the Buick SUVs. Carrying over the same incredible 30-inch digital infotainment and navigation system, the Buick Enclave ups the ante in terms of overall engine power and performance.
Powered by a 2.5-liter, 4-cylinder turbocharged engine, the Buick Enclave attains an astonishing 329 horsepower and 326 pound-feet of torque for an outstanding 5,000-pound towing capacity. It attains an incredibly fuel-efficient 20 MPG for city driving, 27 MPG for highway driving, for an overall 23 MPG combined.

Simple Tips to Improve Fuel Economy
No matter what Buick SUV you choose, here are some time-tested tips that always help to improve fuel economy.
- First, try to accelerate smoothly. While there may be times you need to quickly accelerate during an emergency maneuver, maintaining a steady acceleration helps the transmission and engine achieve a more reliable and efficient RPM.
- Second, always ensure your tires are properly inflated. Under-inflated or over-inflated tires can both decrease fuel economy, so ensure your tires are inflated to the suggested PSI rating.
- Third, focus on driving at consistent speeds. Use the cruise control feature on the highways. Fourth, limit the amount of weight your Buick SUV has. Too much weight can increase fuel consumption. Finally, limit how often you leave your Buick idling.
