One of the most common questions among Nissan Maxima owners in Canada is whether their vehicle requires premium gasoline or if they can save money by using regular unleaded fuel. The short answer is that premium fuel is recommended but not necessarily required for Nissan Maximas, according to the owner’s manuals.


Nissan’s official guidance states that premium gasoline with an octane rating of 91 or higher is “recommended” for optimal performance and efficiency. However, the manuals also note that regular unleaded gasoline with an octane rating of 87 can be used if premium fuel is not available or if cost savings are desired.


Using regular gasoline in a Nissan Maxima is unlikely to cause any immediate issues or engine damage. However, there may be some potential downsides and trade-offs to consider. With regular fuel, drivers may experience a slight decrease in horsepower and torque output, which could translate to slightly less responsive acceleration and performance.


Additionally, there is a potential for increased engine knock or pinging at high loads or high RPMs when using lower-octane regular gasoline. This knocking can lead to increased wear and tear on the engine over an extended period. To mitigate this risk, it’s recommended to use top-tier gasoline brands when opting for regular fuel.


On the other hand, using premium gasoline in a Nissan Maxima can provide several benefits. Premium fuel is designed to resist pre-ignition and knock, allowing the engine to operate at its peak performance levels. This can result in smoother operation, maximum horsepower and torque output, and potentially better fuel economy in some cases.


While the differences in real-world performance and fuel economy may be relatively small, using premium gasoline can provide peace of mind and help maximize the longevity of the engine, especially for those who frequently drive in demanding conditions or with heavy loads.

Rising Gas Prices in Canada

Canadian drivers have been feeling the pinch at the gas pumps like never before. Fuel costs have skyrocketed across the country, with prices reaching record highs in recent months. The national average price for regular gasoline surpassed an eye-watering $2 per liter in June 2022, a staggering increase from just a year earlier.

This dramatic spike in gas prices can be attributed to a combination of factors, including the ongoing conflict in Ukraine, supply chain disruptions, and a recovering global demand for oil as pandemic restrictions eased. The impact has been felt nationwide, with some regions like Vancouver and the Greater Toronto Area experiencing prices well above $2.20 per liter.

For many Canadians, these soaring fuel costs have become a significant financial burden, prompting them to explore ways to reduce their gasoline expenditures. One option that has gained traction is the consideration of using regular unleaded gasoline instead of premium, even in vehicles that recommend or were previously filled with higher-octane fuel.

While premium gasoline has traditionally been seen as a necessity for certain vehicles to maintain optimal performance, the potential savings from opting for regular unleaded have become increasingly appealing amidst the current price environment. With the cost difference between regular and premium often exceeding 30 cents per liter, the prospect of saving money at the pump has prompted many drivers to reevaluate their fuel choices.

 

What is Premium Gasoline?

Premium gasoline, often labeled as 91 octane or higher at the pump, is a higher-grade fuel that differs from regular unleaded gasoline in its octane rating and formulation. The octane rating is a measure of a fuel’s ability to resist premature ignition or “knocking” within the engine’s combustion chamber.

Regular unleaded gasoline typically has an octane rating of 87, while premium gasoline is formulated with an octane rating of 91 or higher, depending on the region and fuel supplier. The higher octane rating allows premium gasoline to withstand greater compression within the engine before igniting, making it suitable for high-performance or high-compression engines.

In addition to its higher octane rating, premium gasoline often contains additional additives and detergents that can help keep the engine’s fuel system clean and promote efficient combustion. These additives can contribute to improved performance, reduced emissions, and potentially better fuel economy in some vehicles.

 

Engine Design and Octane Requirements

To understand why some vehicles require premium gasoline while others can run on regular, it’s important to look at engine design and compression ratios. The compression ratio refers to how much the air/fuel mixture is compressed before ignition in the engine’s cylinders. Higher compression ratios allow for more efficient combustion and increased power output.

Engines with high compression ratios, often found in performance vehicles, require higher-octane premium gasoline to prevent premature detonation or engine knocking. Lower-octane regular fuel can ignite too early under these higher pressures, leading to potential engine damage over time.

The Nissan Maxima is powered by a 3.5L V6 engine with a relatively high compression ratio around 10.3:1 to 11.0:1 depending on the model year. While not extreme, this compression ratio puts the Maxima into the category of engines that officially recommend or are designed for premium 91 octane gasoline according to most automakers’ specifications.

Using lower octane 87 regular unleaded gas can lead to sporadic engine knock or pinging during acceleration or high loads in the Maxima’s V6. This pre-detonation may not necessarily cause immediate issues, but it increases cylinder temperatures and pressures that can contribute to increased engine wear over tens of thousands of miles.

 

Potential Downsides of Using Regular Gas in a Nissan Maxima

While using regular 87 octane gasoline in a Nissan Maxima is generally acceptable, there are some potential downsides to be aware of. The primary concern is a slight reduction in power output and performance compared to running the recommended premium fuel.

Maximas are equipped with high-compression engines designed to take full advantage of premium gasoline’s higher octane rating. When using a lower octane fuel like regular unleaded, the engine’s computer has to retard ignition timing to prevent pre-ignition or engine knock. This ignition timing adjustment results in a loss of horsepower and torque.

Estimates vary, but most experts suggest a Maxima could experience a 5-10% reduction in peak horsepower and torque when using 87 octane regular gas instead of 91 octane premium. On a vehicle like the 2023 Maxima with 300 horsepower, that could mean a drop to around 270-285 hp. While this reduction may not be dramatic in ordinary driving, you may notice slightly slower acceleration, especially at higher rpm.

Another potential downside of using regular gas is an increased risk of engine knock or pre-ignition under high loads or high temperatures. The lower octane fuel is less resistant to auto-igniting, which can lead to knocking or pinging sounds from the engine. Prolonged driving with significant engine knock could potentially cause accelerated wear and component damage over time.

It’s also worth noting that using regular gas consistently in a vehicle designed for premium may contribute to slightly increased carbon buildup on intake valves and in the combustion chambers. This buildup can negatively impact performance and efficiency if not addressed through proper maintenance and fuel system cleaners.

 

Benefits of Using Premium Gas in a Nissan Maxima

While using regular gasoline in a Nissan Maxima is generally acceptable, there are several key benefits to using the recommended premium fuel. Premium gasoline with a higher octane rating allows the engine to extract maximum performance from the designed compression ratios and ignition timing.

Filling up with premium 91 octane unlocks the full potential of the Maxima’s powerful V6 engine. Horsepower and torque output are maximized, resulting in superior acceleration and responsiveness. The higher octane prevents pre-ignition and engine knock, allowing the engine computer to advance timing for peak power delivery.

Beyond raw performance, using premium gasoline in a Nissan Maxima promotes smoother and more refined operation. The engine runs with less strain and vibration when the correct high-octane fuel is supplied. This results in a more enjoyable driving experience with linear power delivery.

Perhaps most importantly, premium gasoline helps protect the Maxima’s engine over the long term. The higher octane rating prevents detonation and engine knock, especially under high loads and demanding driving conditions. This mitigates excessive heat and stress that can lead to increased wear on pistons, rings, and other internal components.

While Nissan states the Maxima can run on regular fuel, using premium gasoline as recommended provides maximum protection and helps promote longevity. This peace of mind can pay dividends in preserving the engine’s health for higher mileage down the road.

 

Fuel Quality and Top Tier Gasoline

While the octane rating is important, the overall quality of the gasoline can also impact engine performance and longevity. Not all regular 87 octane fuels are created equal. Some budget gas brands may use lower-quality additives or have fewer detergents, which can lead to increased carbon deposits and injector fouling over time.

This is why it’s recommended to use “Top Tier” gasoline, regardless of whether you opt for regular or premium. Top Tier is a designation for gasoline brands that meet stringent standards for engine cleanliness and performance additives. Major companies like Shell, Esso, Petro-Canada, and others are certified as Top Tier.

Using Top Tier gas helps prevent build-up in your engine by providing a higher level of detergents and cleaning agents. This keeps vital components like fuel injectors, intake valves, and combustion chambers free of deposits. In the long run, sticking to Top Tier fuel can improve fuel economy, restore lost power, reduce emissions, and prolong your engine’s life.

So even if you decide that regular 87 octane is suitable for your driving needs, be sure to fill up at reputable Top Tier stations. Avoiding lower-quality bargain gas can prevent many headaches and potential repair costs down the road.

 

Cost Analysis: Premium vs Regular Gas

To determine if using premium gas is worth the extra cost for Nissan Maxima owners in Canada, it’s important to analyze current fuel prices and calculate the potential annual expenses for each grade. As of mid-2023, the average price for regular 87 octane gasoline in major Canadian cities like Toronto and Vancouver hovers around $1.50 per liter. In contrast, premium 91 octane fuel typically costs around $1.80 per liter – a difference of roughly 30 cents.

 

For a Nissan Maxima driver who travels 20,000 km annually with a combined fuel economy of 9 L/100 km, the yearly gasoline costs would be as follows:

 

Regular 87 Octane Gasoline:

20,000 km / 100 = 2,000 L of fuel consumed

2,000 L x $1.50 per liter = $3,000 annually

 

Premium 91 Octane Gasoline:

20,000 km / 100 = 2,000 L of fuel consumed

2,000 L x $1.80 per liter = $3,600 annually

 

The difference in annual fuel costs between using regular and premium gasoline for this example Maxima amounts to $600. This means a driver would pay an extra $50 per month on average by opting for the recommended premium fuel grade. Over the course of several years of ownership, these costs can add up substantially.

 

Nissan’s Official Guidance

When it comes to the official guidance from Nissan on what type of gasoline to use in Maxima models, the automaker’s stance is clear in the owner’s manuals. Across all recent model years, Nissan recommends the use of premium unleaded gasoline with an octane rating of 91 or higher in Maxima vehicles.

The wording used is that premium fuel is “recommended” rather than explicitly “required.” However, Nissan does state that using a lower octane gasoline may reduce performance and could potentially cause engine damage over time.

This premium gasoline recommendation applies to all Maxima models equipped with Nissan’s VQ35DE 3.5L V6 engine, which has been the standard powerplant since the early 2000s. Older Maximas with different engines may have varying fuel requirements listed in their respective owner’s manuals.

It’s worth noting that Nissan’s recommendation for premium fuel does not differentiate between different trim levels or Maxima model years. Whether you drive a base S model or a top-of-the-line Platinum, the official guidance remains the same – use 91 octane or higher gasoline for optimal performance and engine protection.

 

Using Fuel Injector Cleaners

While using regular 87 octane gasoline in a Nissan Maxima is generally acceptable, it can potentially lead to increased carbon buildup over time on the engine’s fuel injectors and intake valves. This buildup occurs because regular gasoline lacks some of the detergent additives found in premium grades that help keep these components clean.

To mitigate this issue, Canadian Maxima owners using regular gas should consider adding a fuel injector cleaner to their vehicle’s gas tank every 5,000-10,000 km or according to the product’s recommended intervals. Fuel injector cleaners contain potent detergents designed to remove stubborn carbon deposits and keep the fuel system operating at peak efficiency.

Some highly rated fuel injector cleaner products for Canadian drivers include Chevron’s Techron Concentrate Plus, Gumout Regane, and Liqui Moly’s Jectron gasoline additive. These are widely available at automotive retailers like Canadian Tire, Walmart, and online. Following the product instructions carefully is crucial to avoid any negative impacts.

In addition to fuel injector cleaners, some Maxima owners opt for an induction service every 50,000-60,000 km at their dealership or local repair shop. This involves removing the intake manifold and using specialized cleaning tools to thoroughly remove built-up carbon deposits that basic fuel additives can’t fully address.

Regularly using a high-quality fuel injector cleaner and considering periodic induction services can go a long way toward ensuring optimal performance and fuel economy when running regular gasoline in a Nissan Maxima. These practices can help offset some of the downsides of forgoing premium fuel.

 

Monitoring for Performance Issues

If you decide to use regular 87 octane gasoline in your Nissan Maxima, it’s important to monitor for any potential performance issues or signs of engine knock. While unlikely to cause immediate problems, the lower octane fuel may lead to minor drivability concerns over time.

One key symptom to watch for is engine knock or pinging during acceleration or under load. This metallic pinging noise is caused by premature ignition of the fuel-air mixture and can indicate the need for higher octane gasoline. Prolonged engine knock can potentially lead to increased wear or even engine damage.

You may also notice slight decreases in power output or acceleration performance when using regular fuel compared to premium. The engine’s computer works to prevent knock by retarding ignition timing, which reduces power. While minor, this difference in responsiveness may be noticeable during highway merging or passing maneuvers.

If you experience persistent engine knock or a noticeable drop in power after switching to regular gas, consider trying a higher quality top-tier gasoline brand or reverting to premium fuel. Diagnosing drivability issues early can prevent escalating problems down the road.

 

Potential Void of Warranty Coverage

One concern for Nissan Maxima owners considering using regular unleaded gasoline is the potential impact on their vehicle’s warranty coverage. While Nissan recommends premium fuel, they do not explicitly state that using regular gas will void the warranty. However, there may be exceptions or limitations to consider.

According to Nissan’s warranty documentation, the use of “gasoline with an octane rating lower than recommended” could potentially void certain warranty coverages related to engine components or performance issues. This is because running a lower octane fuel than specified can lead to increased engine knock, pre-ignition, and accelerated wear over time.

If a Maxima owner experiences an engine failure or related issue that can be directly attributed to using regular gasoline instead of premium, Nissan may deny warranty claims or coverage for repairs. This is particularly true if the vehicle’s maintenance records show a consistent pattern of using lower octane fuel against the manufacturer’s recommendations.

However, it’s important to note that isolated incidents or occasional use of regular gas may not necessarily void warranty coverage entirely. Nissan’s stance is generally that if there is no evidence of engine damage or decreased performance directly caused by the fuel octane, they will likely still honor the warranty terms.

To avoid any potential issues or disputes, Nissan Maxima owners should carefully review their vehicle’s warranty documentation and consult with a certified Nissan dealer or technician if they have specific concerns about using regular unleaded gasoline and its impact on their warranty coverage.

 

Short vs Long-Term Considerations

When deciding whether to use regular or premium gasoline in a Nissan Maxima, it’s essential to weigh both the short-term cost savings and potential long-term implications. While regular fuel may provide an immediate reduction in fuel expenses, it could potentially lead to increased maintenance costs and decreased engine longevity over time.

In the short term, the price difference between regular and premium gasoline can be significant, especially when gas prices are high. For example, if regular gas costs $1.50 per liter and premium costs $1.80 per liter, using regular fuel in a Maxima could save around $10 to $15 per fill-up. Over the course of a year, this could translate to savings of several hundred dollars for the average driver.

However, it’s crucial to consider the potential long-term impacts of using a lower-octane fuel than recommended by the manufacturer. While Nissan states that regular gasoline is an acceptable option for the Maxima, it may lead to increased engine wear, reduced performance, and a higher risk of engine knock or pre-ignition over time.

Engine knock, caused by premature ignition of the fuel-air mixture, can potentially damage engine components like pistons, rings, and bearings if left unchecked. This type of damage can be costly to repair and may even necessitate a complete engine overhaul or replacement in severe cases.

Additionally, using regular gasoline could potentially void certain aspects of the Maxima’s warranty coverage, leaving owners responsible for any repair costs related to fuel-related issues. It’s essential to review the warranty terms and conditions carefully before opting for a lower-octane fuel.

When considering the overall ownership costs of a Nissan Maxima, the potential long-term repair expenses associated with using regular gasoline may outweigh the short-term savings at the pump. It’s crucial to factor in the vehicle’s expected lifespan, anticipated mileage, and the cost of potential repairs or premature engine replacement when making this decision.
