Can You Use Regular Gas in a Volvo XC40?

Can You Use Regular Gas in a Volvo XC40?

Premium gasoline, often referred to as high-octane or super unleaded fuel, is a type of gasoline with a higher octane rating than regular unleaded gasoline. The octane rating measures a fuel’s resistance to premature ignition or “knocking” in the engine’s combustion chamber.

In Canada, regular unleaded gasoline typically has an octane rating of 87, while premium gasoline is rated at 91 octane or higher. Some stations may offer even higher octane levels, such as 93 or 94. The higher the octane rating, the more resistant the fuel is to engine knocking, which can cause damage and reduce performance.

Premium gasoline is designed for use in high-performance engines that have higher compression ratios or forced induction systems like turbochargers or superchargers. These engines require a more stable fuel to prevent knocking and operate at their full potential. Using a higher octane fuel allows the engine to extract more power and efficiency from each combustion cycle.

The 2024 Volvo XC40 is the latest iteration of Volvo’s popular compact luxury SUV, offering a perfect blend of style, comfort, technology, and fuel efficiency. This year’s model boasts several updates and new features that make it an even more compelling choice for Canadian drivers.

Under the hood, the XC40 offers a range of engine options to suit various driving needs and preferences. The base engine is a 2.0L turbocharged 4-cylinder (T5) that delivers a respectable 194 horsepower and 236 lb-ft of torque. For those seeking more power, there’s the 2.0L supercharged and turbocharged 4-cylinder (T6) that generates an impressive 302 horsepower and 295 lb-ft of torque.

Volvo has also introduced mild hybrid variants of the XC40, featuring a combination of a gasoline engine and an electric motor. The B5 and B6 powertrains offer a perfect balance of performance and efficiency, with the B6 producing 295 horsepower and 310 lb-ft of torque while delivering improved fuel economy compared to the traditional gasoline-only engines.

The mild hybrid technology in the XC40 works seamlessly, using the electric motor to assist the gasoline engine during acceleration and cruising, while also enabling regenerative braking to capture energy that would otherwise be lost. This innovative system not only enhances fuel efficiency but also provides a smoother and more responsive driving experience.


Volvo’s Official Fuel Recommendations

Volvo provides clear guidelines on the recommended fuel grades for its vehicles, including the 2024 XC40. The automaker’s fuel recommendations are based on extensive engine testing and engineering to ensure optimal performance, efficiency, and longevity.

For most of its turbocharged and high-performance engines, Volvo recommends using premium unleaded gasoline with an octane rating of 91 or higher. This includes the T5, T6, B5, and B6 powertrains available in the XC40. The higher octane rating helps prevent pre-ignition or engine knock, allowing these engines to achieve their full rated power output.

While premium fuel is the recommended choice, Volvo states that its turbocharged engines can also run on regular 87 octane gasoline without causing any mechanical damage. However, using regular gas may result in slightly reduced performance, fuel economy, and increased emissions compared to premium fuel.

Volvo does note that for optimal efficiency, performance, and to experience the full potential of its advanced turbocharged engines, premium gasoline should be used. This recommendation is especially important for drivers who frequently engage in spirited driving, towing, or operating their vehicle under high loads.


The T5 and T6 Turbocharged Engines

The Volvo XC40 is offered with two potent turbocharged gasoline engine options: the T5 and T6. These are high-performance powerplants designed to deliver thrilling acceleration and drivability.

The T5 is a 2.0L turbocharged four-cylinder producing 248 horsepower and 258 lb-ft of torque. This allows a 0-100 km/h sprint of just 6.4 seconds. The T6 takes things further with both turbocharging and supercharging. Its 2.0L four-cylinder kicks out an impressive 316 hp and 295 lb-ft of torque for breathtaking acceleration.

To extract maximum performance from these advanced forced-induction engines, Volvo mandates the use of premium 91 octane gasoline or higher. The higher octane rating prevents pre-ignition and engine knock, especially under high loads and RPMs.

Using lower-grade 87 octane regular unleaded fuel can reduce power output and efficiency. It may also cause knocking or pinging sounds from the engine on hard acceleration. Over time, this can potentially lead to increased engine wear or even damage.

While the T5 and T6 engines are technically capable of running on regular gas, it comes at the cost of diminished performance. Drivers looking to unlock the full potential of these turbocharged powerhouses should stick with premium 91+ octane fuel as Volvo recommends.


The Mild Hybrid B5 and B6 Powertrains

For the 2024 model year, Volvo has introduced new mild hybrid powertrains for the XC40 compact luxury SUV. These setups pair a turbocharged gasoline engine with a small electric motor and 48V battery pack to provide an efficiency boost.

The B5 powertrain consists of a 2.0L turbocharged four-cylinder engine and a mild hybrid system. This setup produces a combined 247 horsepower and 258 lb-ft of torque. The B6 features the same 2.0L turbo engine but adds a supercharger, resulting in 295 hp and 310 lb-ft.

Like the non-hybrid T5 and T6 engines, Volvo requires premium 91 octane or higher gasoline for the B5 and B6 mild hybrids. Using lower octane fuel can cause pre-ignition and knocking, which reduces power output and efficiency. It could also potentially damage the engine over time.

While the mild hybrid system provides some electric assist and regenerative braking capability, the B5 and B6 are not full hybrids or plug-in hybrids. They still rely primarily on the gasoline engine for propulsion. So premium fuel remains crucial to extract maximum performance from these powertrains.

Volvo states that the higher energy content of premium fuel allows the turbochargers and engine computer calibrations to safely extract more power. This results in better acceleration, passing power, and towing capability when using 91 octane or higher fuel.


Running the T5/T6/B5/B6 on Regular Gas

While Volvo strongly recommends using premium 91 octane or higher fuel in the turbocharged T5, T6, B5 and B6 engines, the XC40 can still operate on regular 87 octane gasoline without causing any immediate damage. However, there are some notable drawbacks to using the cheaper regular fuel in these performance-oriented powertrains.

Firstly, you will experience a noticeable decrease in power output when running on 87 octane gas. The turbochargers and advanced engine tuning are designed to extract maximum performance from higher octane premium fuel. With regular gas, the engine computer has to pull back on timing and boost pressure to prevent pre-ignition and knocking. As a result, horsepower and torque figures drop compared to using 91 octane or better.

Reduced power means slower acceleration, particularly from a stop or when trying to pass at highway speeds. The XC40 may feel sluggish or underpowered, diminishing the sporty driving experience. Towing capability could also be negatively impacted when using regular fuel.

Fuel economy tends to suffer slightly as well when the engine is operating in a lower state of tune on regular gas. The mileage penalty is relatively small, but over thousands of kilometers it can add up in increased fuel costs that may offset some of the per-tank savings.

Long-term use of regular gasoline in these high-compression turbocharged engines could potentially lead to increased carbon buildup on intake valves and in combustion chambers over time. While unlikely to cause catastrophic failure, it may require more frequent servicing to remove deposits.

In summary, Volvo approves the use of 87 octane regular gas as an acceptable minimum for the T5, T6, B5 and B6 engines when premium is not available. However, enthusiastic drivers seeking peak performance and efficiency will want to opt for 91 octane premium whenever possible.


The Previous T4 Base Engine

While the current 2024 XC40 lineup no longer offers the base T4 engine, it’s worth discussing as it was the lone exception to Volvo’s premium fuel recommendation for the previous generation XC40. The 1.5-liter turbocharged and supercharged 3-cylinder T4 was designed to run perfectly fine on regular 87 octane gasoline.

Volvo still recommended premium 91 octane or higher for optimal efficiency with the T4. However, owners could opt for the more affordable regular gas without any issues. The engine’s lower compression ratio and boost levels allowed it to safely operate on 87 octane fuel.

This provided a more budget-friendly option for XC40 buyers who didn’t need the extra power of the T5 or T6 engines. The T4 delivered respectable performance with 187 hp and 221 lb-ft of torque from the compact 3-cylinder. While a step below the higher trims, it offered sufficient acceleration for most daily driving needs.

So if you had an older XC40 with the T4 engine, using regular gas was perfectly acceptable according to Volvo. But with the latest 2024 model, even the base powertrains now incorporate mild hybrid technology and turbocharging that necessitates premium fuel for peak performance.


Premium vs Regular Gas: Performance

Using premium 91 octane or higher gasoline provides noticeable performance advantages in the 2024 Volvo XC40’s turbocharged and mild hybrid engines. With premium fuel, you’ll experience improved power output, quicker acceleration, and better fuel efficiency.

The high compression turbocharged engines like the T5, T6, B5, and B6 are engineered to extract maximum performance from premium gasoline’s higher octane rating. The increased resistance to pre-ignition or engine knocking allows more advanced ignition timing and higher boost pressures from the turbochargers.

In the XC40 T6 AWD with the 2.0L twincharged engine, Volvo’s official figures show a 16 hp and 22 lb-ft increase in power and torque when using 93 octane fuel versus 87 octane. The 0-60 mph time improves by 0.3 seconds as well. You’ll feel the extra punch when accelerating from a stop or for passing maneuvers.

Fuel efficiency also benefits from premium gas. The higher octane and more efficient combustion process results in slightly better real-world MPG numbers in the XC40. Over thousands of miles of driving, the 1-2 MPG improvement can really add up in fuel cost savings.

While regular 87 octane gasoline is an acceptable choice if you want to save money at the pump, the XC40’s turbocharged performance engines simply operate at their best using premium fuel as Volvo recommends. The power, acceleration, and efficiency gains make it worthwhile for drivers who want to maximize their driving enjoyment.


Premium vs Regular Gas: Cost Analysis

One of the primary considerations for XC40 owners is the price difference between premium and regular gasoline. In Canada, premium 91 octane fuel typically costs around 15-20 cents more per liter than regular 87 octane. This may not seem like a huge gap, but it adds up over time.

For example, if you fill up a 54L tank on the XC40 with regular gas at $1.50/L, it costs $81. Using premium at $1.70/L, that same fill-up is $91.80 – a difference of $10.80 per tank. If you refuel every two weeks, that’s over $280 in extra costs annually just for using premium fuel.

However, potential fuel efficiency gains with premium gas can offset some of those costs. Volvo estimates a 2-3% improvement in combined fuel economy when using 91+ octane in the turbocharged engines. On the XC40 T5 AWD rated at 9.1L/100km combined, that’s a saving of around 0.2L/100km or $50-75 per year if driving 20,000km annually.

So while premium fuel provides more power and potentially very slight efficiency gains, the cost savings of using regular 87 octane are significant over the life of the vehicle. Budget-conscious XC40 owners commuting in the city may opt for regular gas to save hundreds annually. Those wanting maximum performance and who don’t mind the extra cost can stick with premium for their luxury SUV.


Volvo’s Recommendations for Canadians

For Canadian drivers of the 2024 Volvo XC40, the automaker provides clear guidance on fuel requirements. Volvo recommends using premium unleaded gasoline with an octane rating of 91 or higher in all Canadian provinces and territories.

This recommendation applies to the T5, T6, B5, and B6 engine variants found in the latest XC40 models. While regular 87 octane fuel can be used, it may result in reduced performance, efficiency, and output from these turbocharged and hybrid powertrains.

Volvo’s fuel advice is consistent across Canada, regardless of factors like altitude or climate differences between regions. From Vancouver to Halifax, XC40 owners should opt for premium 91+ octane gasoline to experience the full potential of their luxury compact SUV.

However, it’s important to note that using regular 87 octane fuel will not cause any immediate damage or long-term issues with the XC40’s engine. It simply may not unlock the vehicle’s maximum horsepower, torque, and fuel economy figures. This flexibility allows Canadian drivers to choose between optimum performance with premium gas or cost savings with regular fuel as needed.


Environmental Impacts of Fuel Grades

While the debate around premium vs regular gasoline for the Volvo XC40 often centers on performance and cost, it’s essential to consider the environmental implications of your fuel choice. The type of gasoline you pump into your luxury SUV can impact emissions and contribute to air pollution levels.

Premium gasoline, with its higher octane rating, tends to burn more completely compared to regular unleaded fuel. This more efficient combustion results in fewer unburnt hydrocarbons and carbon monoxide being released into the atmosphere. However, premium gas also produces slightly higher carbon dioxide (CO2) emissions due to its higher energy density.

On the other hand, regular 87 octane gasoline may leave more unburnt fuel residues in the engine, leading to increased hydrocarbon and carbon monoxide emissions. These pollutants can contribute to smog formation and negatively impact air quality, especially in urban areas.

It’s worth noting that modern vehicles, including the Volvo XC40, are designed with advanced emission control systems that help mitigate the environmental impact of both fuel grades. However, using the recommended premium gasoline can still provide a slight advantage in terms of overall emissions and efficiency.

Ultimately, the environmental impact of your fuel choice is relatively small compared to factors like driving habits, vehicle maintenance, and overall fuel consumption. Nevertheless, for eco-conscious Canadians, using premium gasoline in the Volvo XC40 may be a more environmentally responsible option, albeit with a slightly higher carbon footprint.


Fuel-Saving Tips for the XC40

While using premium gasoline can help maximize the XC40’s efficiency, there are several other easy steps you can take to boost your fuel economy. These tips apply whether you opt for regular or premium fuel:


Keep Tires Properly Inflated: Underinflated tires create more rolling resistance, forcing the engine to work harder and burn more gas. Check your tire pressures monthly and inflate to Volvo’s recommended PSI.

Remove Excess Weight: The more weight in your XC40, the more fuel required to accelerate and maintain speed. Clear out any unnecessary cargo from the trunk or cabin areas.

Avoid Excessive Idling: Idling gets 0 miles per gallon. Shut off your engine if stopped for more than 30 seconds, except in traffic. Many newer vehicles have auto start/stop technology to prevent excessive idling.

Go Easy on Acceleration: Aggressive driving with heavy acceleration and braking can significantly increase fuel consumption. Accelerate gently and coast when possible to boost efficiency.

Use Cruise Control: Maintaining a constant speed on the highway helps maximize fuel economy. The XC40’s cruise control helps eliminate unnecessary acceleration and deceleration.

Check Your Air Filter: A clogged engine air filter causes the engine to work harder and consume more fuel. Replace filters as recommended to allow optimal airflow.

Consider Driving Modes: Many Volvo models offer selectable driving modes like “Eco” that adjust parameters like throttle response and shift points for better efficiency.


No matter which gasoline grade you prefer, adopting eco-conscious habits can stretch every tank further in your Volvo XC40. Combining premium fuel and smart driving yields the best overall efficiency.


Premium Fuel Myths and Misconceptions

There are several common myths and misunderstandings surrounding premium gasoline that are worth addressing. First, premium fuel does not actually cause your engine to run any “cleaner” or produce fewer emissions compared to regular gas. The octane rating has no direct impact on a vehicle’s exhaust output.

Another myth is that premium gas provides more power or acceleration in vehicles not specifically designed for it. Unless the engine has high compression ratios and advanced engine management systems to take advantage of the higher octane, there will be no real-world benefits. Using premium in a regular car essentially just wastes money.

Some drivers believe that premium fuel contains additives or detergents that help “clean” the engine’s fuel system. However, virtually all gasoline sold in Canada (regular and premium) contains mandatory detergent additive packages. The fuel grade itself does not determine whether it can help reduce deposits and buildup.

There is also a misconception that using a higher octane than recommended, such as 94 ultra-premium, can somehow provide even more power or efficiency gains. In reality, using an octane rating higher than the manufacturer’s specs provides no benefits and simply results in overspending at the pump.

Finally, many still think that premium gas “burns cleaner” and lasts longer, requiring less frequent fill-ups. This is simply untrue, as the octane rating has no influence on BTU energy content or fuel economy. With the same driving patterns, premium and regular gasoline will deliver the same mileage per tank or gallon.


Potential Future Fuel Alternatives

As the automotive industry continues to evolve and prioritize sustainability, alternative fuel sources and electrification are becoming increasingly important. Volvo, like many other manufacturers, is actively exploring and implementing these technologies, which could ultimately impact fuel recommendations for vehicles like the XC40.

One area of focus is the development of advanced biofuels, which are derived from renewable sources such as plant materials or waste products. These fuels have the potential to reduce greenhouse gas emissions and dependence on fossil fuels. While they may still require some level of refining, they could potentially be used in existing gasoline engines with minimal modifications.

Another promising avenue is the continued growth of electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs). Volvo has already introduced several electrified models, including the XC40 Recharge, a fully electric variant of the XC40. As the adoption of EVs and PHEVs increases, the need for traditional gasoline may diminish, at least for certain segments of the market.

Hydrogen fuel cell technology is also being explored as a potential alternative to gasoline. While still in its early stages, hydrogen fuel cells could offer a zero-emission solution for powering vehicles, with water being the only byproduct. However, significant infrastructure challenges would need to be addressed before hydrogen fuel cell vehicles could become widely adopted.

It’s important to note that the transition to alternative fuels and electrification is a gradual process, and traditional gasoline-powered vehicles are likely to remain a significant part of the automotive landscape for the foreseeable future. However, as these technologies continue to advance and gain mainstream acceptance, fuel recommendations and requirements may evolve accordingly, reflecting the changing needs and priorities of the industry and consumers.


Making the Choice for Your Driving

For Canadian drivers of the 2024 Volvo XC40, the choice between using premium or regular gasoline comes down to balancing several key factors. While premium fuel is recommended by Volvo for optimal performance, regular 87 octane gas is an acceptable alternative that can save you money at the pump.

Consider your typical driving needs and habits. If you frequently drive in a spirited manner, tow heavy loads, or routinely travel at highway speeds, the power gains from using 91+ octane fuel may be worthwhile. However, if your XC40 is primarily used for city commuting and lighter duty, you likely won’t notice a major difference using regular gas.

Weigh the trade-offs between upfront costs and long-term expenses. Premium gas is more expensive per litre, but using regular can reduce your engine’s efficiency and may lead to higher servicing costs over time. Many XC40 owners opt for a mix of both fuel grades to balance performance and economy.

Don’t overlook the potential environmental impact of your fuel choice. While premium gasoline allows the XC40’s turbocharged engines to operate at peak efficiency, extracting and refining higher octane fuels is more resource-intensive. Using regular gas results in slightly higher CO2 emissions but reduces the overall environmental toll.

Ultimately, there’s no definitively right or wrong answer. By understanding how premium and regular gasoline affect your driving experience and vehicle costs, you can make an informed decision tailored to your specific needs as a Canadian XC40 owner.
