How far can an Acura MDX go on full tank?
The Acura MDX typically covers about 450 to 550 miles per full tank, depending on the model and driving conditions.
The precise range depends on the vehicle’s fuel efficiency (miles per gallon) and its 19.5-gallon fuel tank capacity. Below is a practical breakdown and simple calculations you can use to estimate range for common configurations.
Fuel tank size and its impact on range
The MDX uses a 19.5-gallon (approximately 74 liters) fuel tank on recent generations, which sets the upper bound for how far you can go on a single tank. The miles you can cover per tank are then a product of this capacity and the vehicle’s miles-per-gallon rating.
Estimated range by mpg scenario
Because actual mpg varies by trim, drivetrain, and driving style, here are straightforward calculations using typical combined mpg figures. Multiply the 19.5 gallon tank by the mpg to estimate range.
- 22 mpg combined: about 430 miles per full tank
- 25 mpg combined: about 490 miles per full tank
- 28 mpg combined: about 546 miles per full tank
These examples illustrate how a modest difference in efficiency translates into hundreds of miles of range. Real-world results may vary with traffic, terrain, cargo, and climate.
Notes on different MDX variants
Hybrid and performance variants typically have different mpg figures, which shifts the practical range accordingly. For precise numbers, consult the EPA ratings for your specific model year and configuration or check the vehicle’s fuel economy label in the window sticker.
Because the MDX lineup includes gasoline and hybrid powertrains, the exact range you experience will vary. The 19.5-gallon tank provides a solid baseline for estimating endurance on a long trip.
Tips to maximize range
To stretch a full tank further, consider the following practices that influence mpg and overall range:
- Drive smoothly: steady speed and gentle acceleration improve efficiency.
- Maintain proper tire pressure and perform routine maintenance.
- Use cruise control on highways when appropriate to maintain consistent speed.
- Lighten the load and remove unnecessary roof racks or cargo boxes on long trips.
- Avoid excessive idling and use A/C judiciously in warm weather.
By adopting these habits, you can often improve real-world range beyond what the EPA's official numbers might suggest for mixed driving.
Real-world considerations
In real-world driving, factors like weather, payload, terrain, and traffic can reduce fuel economy. If you rely on a full tank for a long journey, plan fuel stops based on the lower end of the range to avoid running dry.
Summary
The Acura MDX typically delivers roughly 430-550 miles per 19.5-gallon tank, depending on whether you’re driving a gasoline-only model or a hybrid, and on how you drive. Using simple mpg-based calculations helps you estimate range for your specific configuration, and prudent driving habits can squeeze more miles from each tank.

475 miles
How Far Can the Acura MDX Go On a Tank of Gas? Depending on which configuration drivers select, the 2022 MDX has a driving range of more than 475 miles.
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.
How big is the MDX gas tank?
The Acura MDX has a gas tank size of 18.5 gallons for recent model years, including 2022, 2023, 2025, and 2026. This capacity is standard across most trims and has been consistent for several years.
- Tank Size: 18.5 gallons for all recent models.
- Fuel Type: All models recommend premium unleaded 91-octane gasoline.
- Driving Range: The driving range varies based on driving conditions and configuration, but can be more than 475 miles on the highway in some configurations.
How many miles can an Acura MDX go?
An Acura MDX can last 200,000 to 300,000 miles or more with proper maintenance, and many owners report reaching 300,000 miles and beyond. The key to a long lifespan is consistent and timely maintenance, such as regular oil changes, transmission fluid flushes, and following the manufacturer's service schedule for items like the timing belt.
Factors affecting longevity
- Maintenance is crucial: Adhering to the recommended service schedule is the single most important factor for longevity.
- Engine and transmission: The MDX is known for its reliable engine, but consistent transmission fluid changes are especially important, particularly on earlier models where transmissions have been a known issue.
- Specific model years: Some model years have specific known issues. For example, the 2010-2013 models with the 3.7-liter engine can have oil-burning issues, and it is best to avoid those years if possible.
- High-mileage examples: Owners have reported MDXs reaching well over 300,000 miles, with a 2001 model documented as having over 946,000 miles.
How to maximize your MDX's lifespan
- Follow the maintenance schedule: Stay up to date on all manufacturer-recommended service intervals. Consult your owner's manual for the most accurate information.
- Change transmission fluid regularly: This is a crucial maintenance task to prevent transmission issues.
- Don't skip the timing belt: The MDX uses an interference engine with a timing belt that should be replaced around every 100,000-105,000 miles to prevent catastrophic engine failure. The water pump is usually replaced at the same time.
- Address issues promptly: If you notice any strange noises, leaks, or performance issues, get them checked out immediately to prevent them from becoming more serious and expensive problems.
