The 2020 Buick Encore GX FWD 1.2L achieves 28 MPG combined, making it a reasonably economical choice in the subcompact SUV segment. Buyers accept this level of efficiency because they want a comfortable, stylish, and well-equipped vehicle. It doesn’t break the bank at the pump but still prioritizes features and driving experience over squeezing out every last mile from a gallon of gasoline. This speaks to a buyer who wants something a step above pure econoboxes and is willing to accept slightly lower mileage as a trade-off.

City and highway performance

The EPA estimates of 26 MPG in the city and 30 MPG on the highway accurately reflect the driving experience. The small 1.2L 3-cylinder engine, while surprisingly peppy for its size, works hardest in stop-and-go situations, hence the slightly lower city rating. The continuously variable transmission (CVT), while not always a favorite among driving enthusiasts, does a decent job of keeping the engine in its most efficient rev range on the highway. Don’t expect blistering acceleration, but for relaxed cruising and everyday commuting, the Encore GX delivers adequate performance without excessive fuel consumption. The highway number is perfectly viable for the typical grocery runs people take with their small SUVs.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Buick Encore GX FWD 1.2L at $1,550. This figure is based on driving 15,000 miles per year and using national average fuel prices. If you drive significantly more or less than 15,000 miles, or if fuel prices in your area are substantially higher or lower than the national average, your actual fuel costs will vary accordingly. This figure is a guideline.

Real-world expectations

While EPA estimates provide a standardized benchmark, real-world fuel economy often differs. Factors such as driving style, traffic conditions, and even tire pressure can affect mileage. Owners of the 2020 Buick Encore GX FWD 1.2L generally report figures close to the EPA estimates, though aggressive driving or consistent short trips can lower the overall average. Prioritizing smooth acceleration and maintaining a steady speed on the highway can help achieve or even slightly exceed the EPA’s highway rating. The vehicle’s trip computer provides real-time fuel economy data, allowing drivers to monitor their consumption and adjust their driving habits for optimal efficiency.

How it compares

The 2020 Buick Encore GX’s fuel economy is competitive within its class. The Mazda CX-30, for example, is rated at 25 MPG combined, 22 city, and 30 highway. The Hyundai Kona achieves similar MPG numbers to the Encore GX, hovering in the 27-29 MPG range depending on trim and drivetrain. The slightly smaller Nissan Kicks stands out with with its 31 MPG combined rating, but it sacrifices some of the Encore GX’s refinement and available features, and the more powerful ENCORE MPG across all years may actually generate better real-world MPG. The Chevy Trailblazer, which shares a platform with the Encore GX, delivers effectively identical MPG ratings. Competitors offer very similar numbers, underscoring the reality that this vehicle’s mission is not to be the MPG leader, but to offer a good balance.

Tips to maximize efficiency

The Encore GX’s small engine benefits greatly from smooth and gentle acceleration. Avoid sudden bursts of speed, as this forces the engine to work harder and consume more fuel. Gradually increase your speed to maintain momentum and improve efficiency.

Proper tire inflation is important for both fuel economy and safety. Check your tire pressure regularly and inflate them to the recommended level, which can be found on a sticker inside the driver’s side doorjamb. Underinflated tires increase rolling resistance, leading to lower MPG.

Minimize idling time whenever possible. If you’re stopped for more than a minute, turn off the engine. Modern engines are designed to restart quickly and efficiently, and eliminating unnecessary idling can save a noticeable amount of fuel, especially during city driving.

Consider using cruise control on the highway. Maintaining a consistent speed helps optimize fuel efficiency and reduces the need for continual acceleration and deceleration. Be mindful of traffic conditions and adjust your speed accordingly to avoid sudden braking.

Regular maintenance, including oil changes and air filter replacements, ensures that your Encore GX is running at its peak efficiency. A well-maintained engine is a more efficient engine, and following the manufacturer’s recommended maintenance schedule can help maximize fuel economy and prolong the life of your vehicle.
