Mazda CX-5 Fuel Tank Capacity Explained

The new Mazda CX-5 comes with a fuel tank capacity of approximately 15.3 gallons. This figure holds true across most trims and model years of the current generation. Mazda engineered this tank size to strike a balance between range and vehicle weight. A tank that is too large adds unnecessary pounds, while one that is too small forces frequent stops.

Now, you might wonder if all CX-5 trims share the same number. The answer is mostly yes. Whether you drive the base Sport trim or the premium Signature edition, the gas tank size remains consistent at 15.3 gallons. This standardization makes it easy to compare figures across trims without getting confused by different specifications.

It is worth noting that the CX-5 shares its platform with other Mazda models. The Mazda3 sedan and hatchback, for instance, carry a slightly smaller tank.

Why Tank Size Matters

Tank size directly impacts your driving experience in several ways. A larger tank means fewer gas station visits. It also gives you more flexibility when planning road trips through areas with sparse fuel stations. On the other hand, a smaller tank keeps the vehicle lighter, which can improve handling and fuel economy slightly.

The 15.3-gallon tank in the CX-5 hits a sweet spot. It is large enough to give you meaningful range without weighing down the vehicle. Most drivers will find this capacity more than adequate for daily commuting and weekend getaways alike.

How Far Can You Drive on a Full Tank?

Understanding driving range is one of the most practical reasons to know your fuel tank capacity. The Mazda CX-5 offers a respectable range that makes it suitable for both city driving and highway cruising.

Estimated Range by Engine Type

The CX-5 comes in two main engine configurations. The standard 2.5-liter naturally aspirated four-cylinder engine produces 187 horsepower. The turbocharged 2.5-liter variant bumps that up to 256 horsepower in the CX-5 Turbo. Both engines use the same 15.3-gallon tank, but their fuel consumption differs.

With the standard engine, you can expect an average of 25 to 30 miles per gallon combined. That translates to roughly 380 to 460 miles of total range on a full tank. The turbocharged version tends to sip a bit more fuel, bringing the range down to around 350 to 430 miles depending on driving conditions.

City vs Highway Driving

Your driving environment plays a big role in determining actual range. City driving with lots of stops and starts typically delivers lower MPG. Highway cruising at steady speeds tends to be more efficient. Here is a quick breakdown:

• City Driving: Expect around 22 to 25 MPG, giving you roughly 340 to 380 miles of range.
• Highway Driving: Expect around 28 to 32 MPG, giving you roughly 430 to 490 miles of range.
• Combined Driving: Most real-world drivers fall somewhere in between, averaging 25 to 28 MPG.

These numbers give you a solid baseline. Actual results will vary based on driving habits, road conditions, and vehicle maintenance. To learn more about how fuel efficiency changes over time, check out our piece on does MPG go down with age.

Fuel Economy and MPG Ratings

The Mazda CX-5 has always been praised for its competitive fuel economy. Mazda engineers have worked hard to keep the gas mileage numbers strong without sacrificing performance. The result is a compact SUV that does not punish you at the pump.

EPA Ratings for the New CX-5

The Environmental Protection Agency provides official MPG ratings for every new vehicle sold in the United States. For the 2024 Mazda CX-5 with the standard 2.5L engine, the EPA estimates the following:

• Front-Wheel Drive: 25 city / 31 highway / 28 combined MPG
• All-Wheel Drive: 24 city / 30 highway / 27 combined MPG

The turbocharged CX-5 Turbo with all-wheel drive comes in at around 22 city / 28 highway / 25 combined MPG. These are very competitive numbers for a segment that includes the Honda CR-V, Toyota RAV4, and Nissan Rogue.

What Affects Your MPG?

Several factors influence your real-world fuel economy. Understanding these can help you manage your expectations and improve your numbers over time:

• Driving Style: Aggressive acceleration and hard braking waste fuel. Smooth, steady driving saves gas.
• Vehicle Weight: Adding roof racks, cargo carriers, or heavy cargo increases fuel consumption.
• Tire Pressure: Underinflated tires create more rolling resistance, which reduces MPG.
• Air Conditioning: Running the AC, especially at full blast, increases fuel use.
• Engine Maintenance: Fresh oil, clean air filters, and properly functioning sensors all contribute to better fuel economy.

What Type of Gas Does the Mazda CX-5 Use?

One of the best things about the Mazda CX-5 is that it runs perfectly well on regular unleaded gasoline. You do not need premium fuel. This saves you money every time you visit the pump, and over thousands of miles, those savings add up significantly.

Mazda recommends 87 octane regular gas for all CX-5 models. Using a higher octane fuel will not damage your engine, but it also will not provide any meaningful performance or efficiency benefits. Stick with regular and save your dollars for other things.

Tips for Saving Money on Gas

Fuel costs are one of the biggest ongoing expenses of car ownership. Here are some practical ways to keep your gas spending low in the Mazda CX-5:

1. Fill Up During Cool Hours: Gas is denser in cooler temperatures, so you get slightly more fuel per gallon in the morning or evening.
2. Use Cruise Control on Highways: Maintaining a steady speed improves fuel economy significantly.
3. Avoid Idling: Turn off your engine if you are parked for more than a minute.
4. Keep Your Tires Properly Inflated: Check tire pressure monthly and inflate to the manufacturer recommended levels.
5. Remove Unnecessary Weight: Clean out your trunk and back seat regularly to reduce vehicle load.
6. Plan Your Routes: Combine errands and choose routes with fewer stops and less traffic when possible.
