So, while the tank holds 15.3 gallons, your actual range—the distance you can travel on a full tank—depends on several factors. These include your driving style, road conditions, weather, and even how much cargo or passengers you’re carrying. But on average, you can expect to travel between 380 and 475 miles before needing to stop for gas. That’s enough to get you from Los Angeles to San Francisco, or from Chicago to Detroit, without a single refuel.

In this guide, we’ll dive deep into everything you need to know about the Mazda CX-5’s fuel capacity, efficiency, and real-world performance. Whether you’re a new owner or thinking about upgrading, this article will help you get the most out of every gallon.

Understanding the Mazda CX-5 Fuel Tank Capacity

Let’s start with the basics: the Mazda CX-5’s fuel tank holds **15.3 gallons** of gasoline. This number isn’t arbitrary—it’s carefully chosen to balance range, weight, and vehicle design. A larger tank would increase range but add weight and take up valuable space, while a smaller tank might require more frequent fill-ups, which can be inconvenient on long drives.

Mazda has kept this 15.3-gallon capacity consistent across nearly all CX-5 models since its debut in 2013. Whether you’re driving a 2015 CX-5 Sport or a 2024 CX-5 Carbon Edition, the tank size remains unchanged. This consistency makes it easier for owners to plan fuel stops and compare performance across different model years.

But why 15.3 gallons specifically? It’s a sweet spot for compact SUVs. It’s large enough to provide a respectable range without compromising the vehicle’s agility or fuel efficiency. For context, the Honda CR-V has a 14.0-gallon tank, while the Toyota RAV4 holds 14.5 gallons. The CX-5’s slightly larger tank gives it a small edge in potential range, especially on the highway.

It’s also worth noting that the 15.3-gallon capacity applies to both gasoline and flex-fuel (E85) versions, though flex-fuel models may see reduced efficiency when using ethanol blends. Most U.S. drivers use regular unleaded gasoline (87 octane), which is recommended for optimal performance and fuel economy.

Does the Engine Type Affect Tank Size?

One common question is whether the engine type—like the standard 2.5L four-cylinder versus the turbocharged 2.5L—affects the fuel tank size. The answer is no. Both engines use the same 15.3-gallon tank. However, the turbocharged engine (available on higher trims like the CX-5 Turbo and CX-5 Signature) consumes more fuel under heavy acceleration, which can reduce overall range.

For example, the naturally aspirated 2.5L engine gets up to 26 mpg city / 31 mpg highway, while the turbocharged version drops to around 22 mpg city / 27 mpg highway. That means even with the same tank size, the turbo model may need refueling sooner, especially if you enjoy spirited driving.

Fuel Tank Location and Design

The fuel tank in the Mazda CX-5 is located beneath the rear seats and cargo area, protected by the vehicle’s underbody. This placement helps lower the center of gravity, improving handling and stability. It also keeps the tank away from potential road debris and impacts.

Mazda uses a high-density polyethylene (HDPE) tank, which is lightweight, corrosion-resistant, and durable. This material helps reduce overall vehicle weight, contributing to better fuel efficiency. The tank is also designed with baffles to prevent fuel sloshing during sharp turns or sudden stops, ensuring consistent fuel delivery to the engine.

Fuel Efficiency: How Far Can You Go on 15.3 Gallons?

Now that we know the Mazda CX-5 holds 15.3 gallons, let’s talk about what that means in real-world terms. Fuel efficiency is measured in miles per gallon (mpg), and the CX-5 performs impressively in this category.

According to the U.S. Environmental Protection Agency (EPA), the 2024 Mazda CX-5 achieves the following fuel economy ratings:

– **2.5L Four-Cylinder (FWD):** 26 mpg city / 31 mpg highway / 28 mpg combined
– **2.5L Four-Cylinder (AWD):** 25 mpg city / 30 mpg highway / 27 mpg combined
– **2.5L Turbo (AWD):** 22 mpg city / 27 mpg highway / 24 mpg combined

These numbers place the CX-5 among the most fuel-efficient vehicles in the compact SUV segment. For comparison, the Honda CR-V gets 28/34/30 mpg (FWD), and the Toyota RAV4 achieves 27/35/30 mpg (FWD). While the CX-5 isn’t the absolute leader in highway mileage, it offers a great balance of performance, handling, and efficiency.

Calculating Your Real-World Range

To estimate how far you can go on a full tank, multiply the fuel tank capacity (15.3 gallons) by the combined mpg rating. Here’s what that looks like:

– **2.5L FWD:** 15.3 gal × 28 mpg = **428 miles**
– **2.5L AWD:** 15.3 gal × 27 mpg = **413 miles**
– **2.5L Turbo AWD:** 15.3 gal × 24 mpg = **367 miles**

These are theoretical maximums under ideal conditions—steady highway driving, no traffic, light load, and optimal weather. In real life, most drivers will see slightly lower numbers due to stop-and-go traffic, air conditioning use, and varying terrain.

That said, many CX-5 owners report achieving 380–450 miles on a tank, especially on long highway trips. If you’re a conservative driver who avoids rapid acceleration and maintains steady speeds, you might even exceed the EPA estimates.

Factors That Affect Fuel Economy

Several variables can impact how efficiently your CX-5 uses fuel:

– **Driving Style:** Aggressive acceleration and hard braking can reduce fuel economy by 15–30%. Smooth, gradual inputs help maximize efficiency.
– **Speed:** Driving at 70 mph instead of 60 mph can reduce highway mileage by 10–15%. The CX-5 is most efficient between 45 and 60 mph.
– **Load and Cargo:** Extra weight from passengers, luggage, or roof racks increases fuel consumption. Remove unnecessary items to save gas.
– **Weather:** Cold temperatures reduce engine efficiency, while using the heater or defroster increases load on the engine. Summer driving with AC on can also lower mileage.
– **Tire Pressure:** Underinflated tires increase rolling resistance. Check your tire pressure monthly and keep it at the recommended level (usually 32–35 psi).
– **Idling:** Letting the engine run while parked wastes fuel. Turn off the engine if you’re stopped for more than 30 seconds.

Comparing the CX-5 to Other Compact SUVs

When shopping for a compact SUV, fuel economy is often a top consideration. Let’s see how the Mazda CX-5 stacks up against its closest competitors.

| SUV Model | Fuel Tank Size | Combined MPG | Max Range (Est.) |

| Honda CR-V | 14.0 gal | 28–30 mpg | 392–420 miles |
| Toyota RAV4 | 14.5 gal | 27–30 mpg | 392–435 miles |
| Subaru Forester | 15.9 gal | 26–29 mpg | 413–461 miles |
| Hyundai Tucson | 14.0 gal | 25–28 mpg | 350–392 miles |

As you can see, the CX-5 holds slightly more fuel than the CR-V and Tucson but less than the Forester. However, its efficiency is competitive, especially in the naturally aspirated models.

The CX-5’s real advantage lies in its driving dynamics. While some rivals may offer slightly better fuel economy, the CX-5 delivers a more engaging, car-like driving experience. It handles corners better, has a more refined interior, and offers a quieter cabin—all while maintaining strong fuel efficiency.

Why the CX-5 Stands Out

Mazda has long prioritized “Jinba Ittai”—a Japanese philosophy meaning “horse and rider as one.” This focus on driver engagement sets the CX-5 apart from many competitors that prioritize utility over driving pleasure.

Even with its efficient engine, the CX-5 feels responsive and agile. The steering is precise, the suspension is tuned for comfort and control, and the cabin is designed with high-quality materials. You’re not just saving gas—you’re enjoying the drive.

Tips to Maximize Your Mazda CX-5’s Fuel Efficiency

Getting the most out of your 15.3-gallon tank means adopting smart driving and maintenance habits. Here are some practical tips to help you go farther on every fill-up.

1. Drive Smoothly

Avoid rapid acceleration and hard braking. Instead, anticipate traffic flow and ease into the gas and brakes. This not only saves fuel but also reduces wear on your brakes and tires.

Use cruise control on the highway to maintain a steady speed. The CX-5’s adaptive cruise control (available on higher trims) can even help you maintain a safe distance from the car ahead, reducing the need for frequent speed changes.

2. Keep Up with Maintenance

A well-maintained CX-5 runs more efficiently. Follow the recommended service schedule, which includes:

– Oil changes every 7,500–10,000 miles (or as indicated by the maintenance minder)
– Air filter replacement every 15,000–30,000 miles
– Spark plug replacement every 75,000–100,000 miles
– Fuel system cleaning as needed

A dirty air filter or worn spark plugs can reduce fuel economy by up to 10%.

3. Check Tire Pressure Regularly

Underinflated tires increase rolling resistance, which forces the engine to work harder. Check your tire pressure at least once a month and before long trips. The correct pressure is listed on a sticker inside the driver’s door jamb.

4. Reduce Excess Weight

Remove unnecessary items from your cargo area. An extra 100 pounds can reduce fuel economy by up to 2%. If you don’t need it, leave it at home.

5. Use the Right Fuel

Mazda recommends using regular unleaded gasoline (87 octane) for optimal performance and efficiency. Higher-octane fuel isn’t necessary unless you’re driving a turbocharged model under heavy load—and even then, it’s only beneficial in specific conditions.

Avoid “fuel-saving” additives unless recommended by Mazda. Most don’t provide measurable benefits and can even harm your engine.

6. Plan Your Trips

Combine errands into one trip to avoid multiple cold starts. A warm engine is more efficient than a cold one. Use navigation apps to avoid traffic and find the most fuel-efficient routes.
