Buick Encore Fuel Economy Canada: Real-World Guide

When we shop for a small SUV in Canada, fuel economy rarely feels like a minor detail. Gas prices can swing quickly, winter can stretch for months, and many of us divide our driving between crowded city streets, open highways, and snow-covered suburban roads. That makes Buick Encore fuel economy in Canada an important subject for anyone considering a new or used model.

The first thing we need to clarify is the name. The original Buick Encore and the newer Buick Encore GX are related, but they are not the same vehicle. The original Encore was a smaller, rounded subcompact SUV sold through the 2022 model year in Canada. The Encore GX arrived as a roomier, more modern alternative and is now the Encore model Canadians will normally find at Buick dealerships.

Official fuel-consumption numbers give us a useful starting point, but they do not tell the entire story. A rating produced under controlled conditions cannot completely reflect a February morning in Winnipeg, stop-and-go traffic in Toronto, steep roads around Vancouver, or a roof box packed for a trip through the Rockies.

So, how efficient is the Buick Encore in actual Canadian driving? Let’s look at the numbers, the factors that influence them, and the practical steps we can take to spend less time and money at the pump.

Buick Encore Fuel Economy in Canada at a Glance

Fuel consumption varies by model year, engine, transmission, drivetrain, temperature, and driving style. As a broad guide, Canadian Encore and Encore GX models commonly fall within the following ranges:

Buick model and configuration	Approximate city economy	Approximate highway economy	Typical combined range
Original Encore FWD	8.5–9.5 L/100 km	7.0–7.8 L/100 km	7.8–8.7 L/100 km
Original Encore AWD	9.5–10.5 L/100 km	7.5–8.3 L/100 km	8.6–9.5 L/100 km
Encore GX FWD	8.0–8.5 L/100 km	7.5–7.8 L/100 km	7.8–8.2 L/100 km
Encore GX AWD	9.1–9.3 L/100 km	Approximately 8.4 L/100 km	Approximately 8.8–8.9 L/100 km

These are general comparisons rather than universal numbers for every model year. Buyers should always check the EnerGuide label, the specific model-year fuel-consumption guide, or the vehicle’s original specifications.

For reference, Buick Canada lists the 2025 Encore GX FWD at approximately 8.0 L/100 km city and 7.6 L/100 km highway. The 2025 Encore GX AWD is listed at approximately 9.1 city and 8.4 highway. The 2026 Encore GX AWD is listed at approximately 9.2 city and 8.4 highway.

That difference may look small on paper, but over thousands of kilometres it can become noticeable.

Understanding Canadian Fuel-Economy Ratings

In Canada, fuel consumption is normally expressed in litres per 100 kilometres, written as L/100 km.

A lower number is better.

For example:

• 7.5 L/100 km is more efficient than 9.5 L/100 km.
• A vehicle using 8.0 L/100 km consumes eight litres to travel 100 kilometres.
• A vehicle using 10.0 L/100 km consumes ten litres over the same distance.

Natural Resources Canada publishes model-specific fuel-consumption information for vehicles sold in the country. The combined rating is calculated using a mix of approximately 55 percent city driving and 45 percent highway driving.

Why Official Numbers Are a Comparison Tool

Official ratings are created through standardized testing procedures. They allow us to compare one vehicle with another under consistent conditions. Natural Resources Canada explains that manufacturers generate consumption data using controlled laboratory tests and analytical procedures, while the federal government compiles and publishes the information.

That makes the numbers valuable, but they are not promises.

Think of an official rating as a measuring tape rather than a crystal ball. It can show how two vehicles compare, but it cannot perfectly predict what either one will consume during our daily routine.

Original Buick Encore Versus Encore GX

The word “Encore” can create confusion in used-vehicle listings. We may see an original Encore parked beside an Encore GX and assume the GX is simply a trim level. It is actually a distinct model.

The Original Buick Encore

The original Encore is a very compact crossover with a short wheelbase, upright seating position, and turbocharged four-cylinder engine. Its tidy dimensions make it easy to park, especially in dense urban areas.

Canadian versions were commonly offered with front-wheel drive or all-wheel drive. Although the vehicle is small, its older engine and transmission design means it is not always dramatically more efficient than a newer, slightly larger crossover.

The Buick Encore GX

The Encore GX is longer, roomier, and more modern. Recent Canadian versions use a turbocharged three-cylinder engine. Depending on the model year and configuration, buyers may encounter front-wheel drive paired with a continuously variable transmission or all-wheel drive paired with a conventional automatic transmission.

The current Canadian lineup centres on the Encore GX. Buick’s 2026 model page lists a 1.3-litre turbo engine, while AWD versions use a nine-speed automatic transmission.

Why the GX Can Be More Efficient

A newer engine does not need to be larger to deliver useful torque. Turbocharging helps the small engine generate power when required, while modern transmission programming aims to keep engine speed low during light driving.

As a result, an Encore GX FWD may use less fuel than an older original Encore, even though the GX offers more passenger and cargo room.

Buick Encore GX FWD Fuel Economy

For Canadians focused primarily on fuel savings, the front-wheel-drive Encore GX is generally the strongest option.

Buick Canada lists the 2025 Encore GX FWD at roughly:

• 8.0 L/100 km in the city
• 7.6 L/100 km on the highway

Those figures are competitive for a non-hybrid small crossover, although the small gap between city and highway ratings may surprise some shoppers.

Why the Highway Number Is Not Much Lower

Small turbocharged crossovers tend to perform well at moderate speeds, but aerodynamic resistance rises quickly as speed increases. The Encore GX may feel compact while parked, yet it still has the upright body of an SUV.

At 100 km/h, the engine is pushing a neat little box through the air. At 120 km/h, that box starts behaving more like a sail. The faster we travel, the harder the engine must work.

Who Should Choose Front-Wheel Drive?

FWD makes sense when we:

• Live in an area where roads are cleared regularly.
• Spend most of our time in cities or on major highways.
• Use high-quality winter tires.
• Do not regularly climb steep, snow-covered roads.
• Prioritize lower purchase and fuel costs.

Front-wheel drive can work well in many Canadian communities when paired with proper winter tires. AWD provides additional traction in certain conditions, but it does not shorten braking distances on ice.

Buick Encore GX AWD Fuel Economy

All-wheel drive is attractive in Canada. It offers reassuring traction when pulling away on snow, climbing a slippery driveway, or driving along an unplowed road.

The trade-off is higher fuel consumption.

The 2025 Encore GX AWD is rated at approximately 9.1 L/100 km city and 8.4 L/100 km highway, while Buick lists the 2026 AWD version at approximately 9.2 city and 8.4 highway.

Why AWD Uses More Fuel

An AWD vehicle normally carries extra mechanical components. Those components add weight and create additional friction within the drivetrain.

The engine must move:

• A heavier vehicle.
• Additional shafts and gears.
• Larger or heavier wheel-and-tire combinations on some trims.
• A drivetrain with greater mechanical resistance.

The difference may be only around one litre per 100 kilometres, but fuel costs accumulate quietly, like loose change disappearing into a couch.

Is the AWD Penalty Worth It?

That depends on where and how we drive.

AWD may be worth the extra fuel if we regularly face:

• Deep snow.
• Unpaved rural roads.
• Steep hills.
• Cottage access roads.
• Poorly maintained winter routes.
• Frequent trips to ski areas or mountain regions.

For a driver who stays mainly on cleared urban roads, FWD with premium winter tires may provide a better balance of efficiency and winter capability.

Calculating Annual Buick Encore Fuel Costs

Official ratings become easier to understand when we convert them into dollars.

Suppose we drive 20,000 kilometres per year in an Encore GX averaging 8.0 L/100 km.

The calculation is:

20,000 ÷ 100 × 8.0 = 1,600 litres per year

At $1.60 per litre:

1,600 × $1.60 = $2,560 per year

Now imagine an AWD version averaging 9.0 L/100 km:

20,000 ÷ 100 × 9.0 = 1,800 litres

At the same fuel price:

1,800 × $1.60 = $2,880 per year

The difference is approximately $320 annually.

Estimated Annual Fuel-Cost Examples

Annual distance	Average consumption	Fuel used annually	Cost at $1.60/L
12,000 km	8.0 L/100 km	960 L	$1,536
16,000 km	8.0 L/100 km	1,280 L	$2,048
20,000 km	8.0 L/100 km	1,600 L	$2,560
20,000 km	9.0 L/100 km	1,800 L	$2,880
25,000 km	9.0 L/100 km	2,250 L	$3,600

Fuel prices vary by province, city, season, and market conditions, so these examples should be treated as planning estimates.

How Far Can a Buick Encore GX Travel on One Tank?

The 2024 Encore GX specifications list a fuel-tank capacity of approximately 50 litres for both FWD and AWD configurations.

Theoretical range can be estimated with a simple calculation.

At 8.0 L/100 km:

50 ÷ 8.0 × 100 = 625 kilometres

At 9.0 L/100 km:

50 ÷ 9.0 × 100 = 556 kilometres

However, we should not expect to use every litre before refuelling. The low-fuel warning appears while fuel remains in the tank, and running nearly empty is not a sensible routine.

Practical Driving Range

A realistic fill-to-fill range might be:

• Approximately 500–580 km in mixed FWD driving.
• Approximately 450–530 km in mixed AWD driving.
• Less during harsh winter conditions.
• More during gentle, warm-weather highway travel.

The Driver Information Centre can display average fuel economy and estimated fuel range, allowing owners to follow consumption without calculating every trip manually.

Real-World Buick Encore Fuel Economy

Real-world consumption can differ substantially from the official figure. One driver may average 7.7 L/100 km while another sees 10.5 L/100 km in the same model.

Neither result automatically means something is wrong.

Typical Warm-Weather Expectations

During mild weather, we might reasonably see:

• 7.0–8.0 L/100 km on relaxed highways.
• 8.0–9.5 L/100 km in mixed driving.
• 9.0–11.0 L/100 km in dense city traffic.

Typical Winter Expectations

During a Canadian winter, consumption may rise to:

• 9.0–11.0 L/100 km in mixed driving.
• 10.0–13.0 L/100 km during repeated short trips.
• Even higher during extreme cold, heavy snow, or long idling periods.

These are practical ranges rather than official ratings. Actual results depend on temperature, trip length, speed, traffic, maintenance, tires, and driving habits.

Why Canadian Winters Reduce Fuel Economy

Winter does not merely make the cabin colder. It changes nearly everything the vehicle must do.

Cold Engines Use More Fuel

An engine operates most efficiently after reaching normal temperature. During a five-minute winter trip, it may spend most of the journey warming up.

That means short trips can be surprisingly thirsty. The Encore may be small, but it cannot negotiate with physics.

Winter Fuel Blends

Seasonal gasoline formulations can contain less energy per litre than summer blends. The difference is not always obvious at the pump, but it may appear in the trip computer.

Thick Fluids and Increased Resistance

Cold engine oil and transmission fluid are thicker. Bearings, gears, seals, and other moving parts create more resistance until they warm up.

Winter Tires

Winter tires provide valuable cold-weather grip, but their softer compounds and more aggressive tread patterns may increase rolling resistance.

The effect is usually modest, and the safety benefit is far more important than saving a small amount of fuel.

Snow, Slush, and Wind

Driving through snow is like walking through shallow water. The vehicle must continually push material aside. Strong winter winds also make the engine work harder, especially at highway speeds.

Cabin Heating and Defrosting

Traditional cabin heat largely uses warmth from the engine, but the blower fan, heated seats, heated steering wheel, rear defroster, mirrors, and other electrical systems still create demand.

The bigger fuel penalty often comes from prolonged idling while we wait for the cabin to become warm.

City Versus Highway Consumption

The Encore GX is often purchased as an urban crossover, but city driving can be its toughest environment.

Why City Driving Consumes More

Every acceleration requires energy. When we brake, much of that energy becomes heat and disappears.

Urban driving typically includes:

• Frequent stops.
• Traffic lights.
• Congestion.
• Low-speed acceleration.
• Parking manoeuvres.
• Short trips.
• Extended idling.

A conventional gasoline Encore cannot recover braking energy the way a hybrid can. That is one reason a hybrid competitor may have a significant advantage in heavy urban traffic.

Highway Driving Is Not Automatically Efficient

A steady highway speed usually improves fuel economy, but only to a point. Driving at 90 or 100 km/h is often more efficient than travelling at 115 or 120 km/h.

Aggressive speed changes also matter. Repeatedly accelerating to pass and then braking behind traffic can erase much of the highway advantage.

The Sweet Spot

The best results often appear when we:

• Maintain a steady, moderate speed.
• Use cruise control on relatively flat roads.
• Leave enough following distance to avoid unnecessary braking.
• Accelerate gently after slowdowns.
• Remove unused roof accessories.

Does the Encore Require Premium Gas?

Most Buick Encore and Encore GX owners use regular unleaded gasoline, but the correct fuel should always be confirmed in the owner’s manual or on the fuel-filler label for the specific model year.

Using a higher octane than required does not automatically improve fuel economy. Premium gasoline resists engine knock, but it does not contain magic energy that turns a commuter crossover into a fuel-sipping machine.

If regular fuel is recommended, premium may offer little or no financial benefit.

Avoiding Low-Quality Fuel

Where we buy gasoline can matter more than choosing an unnecessarily high octane. Consistent fuel quality and proper maintenance help the engine-management system operate as designed.

How Driving Style Changes Consumption

The driver has more influence than many of us realize. Two identical Encores travelling along the same route can produce very different averages.

Smooth Acceleration

Turbocharged engines respond quickly when we press the accelerator. That punch feels satisfying, but frequent boost consumes more fuel.

We do not need to crawl away from every traffic light. We simply need to accelerate progressively rather than treating each green light like the start of a rally stage.

Look Far Ahead

Watching traffic several vehicles ahead helps us anticipate slowdowns. Instead of accelerating toward a red light and braking sharply, we can lift earlier and coast.

Control Highway Speed

Aerodynamic drag rises rapidly with speed. A small reduction in cruising speed can produce a meaningful improvement during long journeys.

Limit Idling

An idling vehicle achieves exactly zero kilometres per litre. In extreme cold we may need a brief warm-up, but the engine generally warms more effectively once the vehicle is driven gently.

Combine Short Trips

Several cold starts can consume more fuel than one longer trip covering the same total distance. Combining errands allows the engine to remain warm.

Maintenance Tips for Better Fuel Economy

Fuel consumption can gradually worsen without triggering an obvious warning light. Routine maintenance helps preserve efficiency.

Check Tire Pressure Regularly

Cold temperatures reduce tire pressure. Underinflated tires increase rolling resistance and can affect handling and tread life.

Check pressure when the tires are cold and follow the value on the driver’s door-jamb label—not the maximum pressure printed on the tire sidewall.

Use the Correct Engine Oil

Modern turbocharged engines depend on oil of the correct viscosity and specification. The wrong oil can affect lubrication, cold starts, turbocharger protection, and efficiency.

Replace a Dirty Air Filter When Needed

Modern engine controls can compensate for moderate filter restriction, but a badly neglected filter may still affect performance. More importantly, inspection provides an opportunity to identify dirt, leaves, or damage within the intake system.

Watch for Alignment Problems

A vehicle that pulls to one side or wears tires unevenly may have an alignment issue. Misalignment creates resistance, forcing the engine to work harder.

Address Warning Lights

An illuminated check-engine light may indicate a problem affecting fuel delivery, ignition, emissions controls, or sensor readings. Delaying diagnosis can increase both fuel consumption and repair costs.

Tires and Wheels Matter More Than We Think

Large wheels often look sharper, especially on upper trims, but they can carry an efficiency penalty.

Larger wheel-and-tire packages may be:

• Heavier.
• Wider.
• More expensive to replace.
• More resistant to rolling.
• Less forgiving over rough pavement.

A stylish 19-inch wheel can dress up the Encore GX like a tailored pair of shoes, but a smaller wheel with an efficient tire may be the more sensible running shoe.

Choosing Replacement Tires

When replacing tires, consider:

• The original size and load rating.
• Rolling-resistance characteristics.
• Wet braking performance.
• Snow and ice capability.
• Noise levels.
• Expected tread life.

Fuel economy should never come at the expense of safe braking and dependable winter grip.

Roof Racks and Cargo Affect Fuel Use

Extra weight matters most during acceleration, while aerodynamic accessories matter most at highway speed.

An empty roof basket, cargo box, or crossbar setup may reduce efficiency even when it carries nothing. Once installed, it sits in the airflow like a hand held outside a moving window.

Remove roof accessories when they are not needed. Inside the vehicle, avoid carrying heavy items for weeks without a reason.

A few reusable bags will not transform fuel consumption. A trunk full of tools, sports equipment, or renovation materials might.

Fuel Economy for Different Canadian Drivers

There is no single “normal” Encore fuel-consumption result because Canadian driving patterns vary enormously.

Toronto or Montréal Commuter

Heavy traffic, short trips, and repeated stops may produce consumption around 9–11 L/100 km, particularly during winter.

Prairie Highway Driver

Long, flat routes may support excellent warm-weather results. Strong winds, extreme cold, and high speeds can quickly raise consumption.

Vancouver Driver

Mild temperatures may help, but hills, congestion, and wet conditions can offset some of the advantage.

Atlantic Canada Driver

Rolling roads, coastal winds, winter storms, and mixed rural driving can create highly variable numbers.

Northern or Rural Driver

Long distances may favour steady-speed economy, but deep cold, snow, gravel roads, remote idling, and AWD use can increase fuel demand.

Buick Encore Versus Hybrid Competitors

The Encore GX is reasonably economical for a gasoline-powered small crossover, but it is not a hybrid.

A hybrid may use noticeably less fuel in city traffic because it can:

• Recover energy while slowing.
• Move at low speeds using electric assistance.
• Shut the gasoline engine off more frequently.
• Reduce fuel wasted during idling.

However, hybrids may cost more to purchase. The financial decision depends on annual distance, city-driving percentage, fuel prices, financing, insurance, resale value, and how long we plan to keep the vehicle.

When the Encore Still Makes Sense

The Encore GX may remain appealing when we value:

• A quiet, comfortable cabin.
• Compact dimensions.
• Easy entry and exit.
• A traditional gasoline drivetrain.
• Available AWD.
• A lower used purchase price than some hybrids.
• Buick’s relaxed driving character.

Fuel economy is one chapter in the ownership story, not the entire book.

Is the Buick Encore Good on Gas?

By conventional small-SUV standards, the Encore GX is reasonably efficient, especially in FWD form. A rating near 8.0 L/100 km is respectable for a non-hybrid crossover with an elevated seating position and useful cargo flexibility.

The AWD model is less impressive from a pure fuel-saving perspective. A combined result near 9.0 L/100 km is not excessive, but shoppers prioritizing efficiency should compare it carefully with FWD crossovers and hybrid alternatives.

The original Encore can also deliver acceptable economy, although its age, condition, maintenance history, tires, and drivetrain will influence the result. A neglected FWD Encore may consume more than a well-maintained AWD one.

How to Measure Your Encore’s True Fuel Economy

The dashboard average is convenient, but a manual calculation can provide a more reliable long-term picture.

Follow these steps:

1. Fill the tank until the pump automatically stops.
2. Reset the trip odometer.
3. Drive normally.
4. Refill at the next convenient opportunity.
5. Record litres added and kilometres travelled.
6. Divide litres by kilometres.
7. Multiply the result by 100.

For example:

42 litres ÷ 510 km × 100 = 8.24 L/100 km

Repeat the calculation across several tanks. One fill can be distorted by pump angle, temperature, traffic, weather, or an unusual trip.

Track Consumption by Season

We can learn more by keeping separate averages for:

• Summer.
• Winter.
• City commuting.
• Highway trips.
• Towing or heavily loaded travel.
• Winter tires versus all-season tires.

This makes it easier to recognize a genuine mechanical problem rather than blaming a normal seasonal change.

Warning Signs of Abnormally High Fuel Consumption

A sudden increase deserves attention, particularly when driving conditions have not changed.

Possible warning signs include:

• Fuel economy worsening by 15–20 percent or more.
• Rough idle.
• Hesitation during acceleration.
• Reduced power.
• Strong fuel smell.
• Check-engine light.
• Black exhaust smoke.
• Engine taking unusually long to warm up.
• Brakes that feel hot or seem to drag.
• Tires losing pressure repeatedly.

Potential causes range from low tire pressure to a faulty sensor, sticking brake, ignition problem, thermostat issue, fuel-system fault, or excessive carbon buildup.

A proper diagnosis is more effective than replacing parts at random.

Best Encore Configuration for Fuel-Conscious Canadians

For maximum efficiency, the ideal setup is generally:

• Encore GX with front-wheel drive.
• Smaller factory wheel option.
• Correctly inflated tires.
• No permanent roof box.
• Regular maintenance.
• Moderate highway speed.
• Limited idling.
• High-quality winter tires during cold months.

AWD may still be the better choice where traction needs outweigh the annual fuel difference. The key is choosing it because we genuinely need it—not because every Canadian driveway is automatically an Arctic expedition.

Buying a Used Buick Encore: Fuel-Economy Checklist

A used vehicle’s condition matters as much as its original rating.

Before buying, check:

• Service records.
• Tire size and pressure.
• Uneven tire wear.
• Check-engine or warning lights.
• Cold-start behaviour.
• Idle quality.
• Evidence of oil or coolant leaks.
• Brake condition.
• Alignment.
• Whether the installed wheels match the factory size.
• Current average consumption on the trip computer.

Take a long test drive that includes city and highway sections. Resetting the average before the drive can provide a rough indication, although a short test is not enough to establish true consumption.

A pre-purchase inspection is strongly recommended. Saving a few hundred dollars by skipping one can be like refusing an umbrella because the first raindrop missed us.

Final Verdict on Buick Encore Fuel Economy in Canada

The Buick Encore fuel economy in Canada is best described as reasonable rather than revolutionary.

A front-wheel-drive Encore GX can achieve fuel consumption around 8.0 L/100 km under official testing, making it a sensible choice for drivers who want a comfortable, compact crossover without moving to a hybrid. AWD versions generally consume closer to 9.0 L/100 km combined, with higher figures likely during short winter trips.

The original Encore remains capable of acceptable results, but its real efficiency depends heavily on model year, drivetrain, maintenance, and condition.

Canadian climate has a major influence. Cold starts, winter tires, snow, wind, idling, and short journeys can add litres to the average. That does not necessarily indicate a fault. The best approach is to track consumption over multiple tanks and compare similar seasons.

Ultimately, the Encore rewards smooth driving. Keep the tires properly inflated, reduce unnecessary weight, moderate highway speed, and avoid excessive idling. Small habits may seem insignificant alone, but together they can turn fuel savings from a trickle into a steady stream.

Frequently Asked Questions

1. What is the Buick Encore GX fuel economy in Canada?

The 2025 Encore GX FWD is listed at approximately 8.0 L/100 km city and 7.6 L/100 km highway. The AWD version is rated at roughly 9.1 city and 8.4 highway. Figures vary by model year and configuration.

2. Is the Buick Encore fuel-efficient in winter?

Winter consumption is usually higher. Cold starts, winter gasoline, snow, low tire pressure, thick fluids, cabin heating, and idling can raise fuel use substantially. Short winter trips may exceed 10 L/100 km even when the vehicle has no mechanical fault.

3. Does AWD significantly reduce Encore fuel economy?

AWD may add approximately one litre per 100 kilometres compared with an efficient FWD configuration, although the exact difference varies. The penalty comes from additional weight and drivetrain resistance.

4. How far can an Encore GX travel on a tank?

With a fuel tank of approximately 50 litres, theoretical range may fall around 550–625 kilometres depending on consumption. Practical range is normally lower because drivers refill before using the entire tank.

5. How can we improve Buick Encore fuel economy?

Maintain correct tire pressure, accelerate smoothly, reduce idling, combine short trips, remove unused roof accessories, use the correct engine oil, keep highway speeds moderate, and address warning lights promptly.
