How many gallons does it take to fill up an Acura MDX?
The standard Acura MDX tank holds about 19.5 gallons when full.
In practice, the exact capacity can vary slightly by model year, drivetrain, and hybrid configuration. For the precise figure on your vehicle, check the owner's manual or the official Acura specifications for your exact trim and year.
What this means for drivers
Tank size is a key factor in planning trips, estimating range, and understanding fuel economy in real‑world driving. While 19.5 gallons is the typical capacity, small variations between generations and configurations can affect how many miles you can cover on a full tank.
Fuel tank capacity by generation
Here is a quick look at typical capacities by major MDX generations. Exact capacity can vary by year and trim; always confirm with official specs for your VIN.
- Second generation MDX (2014–2020): 19.5 gallons (73.8 liters).
- Fourth generation MDX (2022–present): 19.5 gallons (73.8 liters).
The MDX Sport Hybrid variants generally use a similar total tank volume, but packaging and calibration can lead to small differences. Always verify for your specific model.
How to verify the exact capacity for your vehicle
To confirm the precise fuel tank capacity for your specific MDX, use these quick checks:
- Check the fuel filler door label, which often lists the tank capacity.
- Consult the owner's manual or the vehicle’s specifications page on Acura’s site.
- Call your local dealer with your VIN for an exact figure.
With the official capacity in hand, you can estimate your driving range using your actual MPG and typical driving conditions.
Estimating driving range
Range depends on MPG, which varies by year, drivetrain, and conditions. In practice, gasoline MDX models typically deliver in the mid- to high-20s on highway driving and lower in city driving. A 19.5‑gallon tank can offer a practical range well into the 400–500 mile territory under typical mixed driving, but your actual range will vary.
Summary
The Acura MDX commonly features a 19.5‑gallon fuel tank, providing a substantial driving range on a full fill. For a precise figure, refer to your vehicle’s manual or the official Acura specifications for your exact model year and trim.

Regardless, every trim is recommended to use premium unleaded 91-octane fuel and has a fuel tank capacity of 18.5 gallons.
Is an Acura MDX good on gas?
The Acura MDX is reasonably fuel-efficient for a three-row SUV, particularly in its front-wheel-drive configuration, which gets an EPA-estimated 19 mpg city / 26 mpg highway / 22 mpg combined. However, its fuel economy varies by drivetrain and trim; the all-wheel-drive (SH-AWD) models are slightly less efficient at 19 mpg city / 25 mpg highway / 21 mpg combined, and the high-performance Type S trims get an estimated 17 mpg city / 21 mpg highway / 19 mpg combined.
By drivetrain
- Front-Wheel Drive (FWD): Offers the best fuel economy at an estimated 19 mpg city / 26 mpg highway / 22 mpg combined.
- Super Handling All-Wheel Drive (SH-AWD): Slightly less efficient than FWD, with ratings around 19 mpg city / 25 mpg highway / 21 mpg combined.
- Type S SH-AWD: The performance-oriented Type S models have the lowest fuel economy, with an estimated 17 mpg city / 21 mpg highway / 19 mpg combined.
Key considerations
- Premium fuel: The manufacturer recommends premium gas for the MDX, but it is not an absolute requirement as it is for models like the NSX.
- Real-world vs. EPA: Some real-world tests have shown slightly better fuel economy than the EPA estimates, particularly on the highway.
- Competitor comparison: While not the most fuel-efficient SUV in its class, the MDX is comparable to many of its competitors.
