How many gallons does a 2008 Acura MDX hold?
The 2008 Acura MDX uses a 21.0-gallon fuel tank (about 79.5 liters).
Understanding this specification helps drivers gauge range, plan refueling stops, and manage trips more efficiently. The figure represents the official tank capacity and serves as a baseline for real-world driving, where miles-per-gallon can vary with conditions and drivetrain configuration.
Official capacity
ACURA lists the 2008 MDX’s fuel-tank capacity at 21.0 U.S. gallons. This is the maximum volume the tank can hold when filled to capacity. In practice, drivers fill to full at a gas station and rely on the gauge, but usable fuel may be slightly less than the stated capacity due to the fuel pickup and reserve design.
Why this matters for drivers
Knowing the official capacity helps with trip planning, fuel budgeting, and understanding the gauge. It also provides a basis for estimating how far the SUV can travel on a full tank, though real-world range depends on driving conditions and MPG.
Estimating real-world range
Because fuel economy varies with driving style, terrain, traffic, and whether the MDX is front- or all-wheel drive, the practical range on a full tank can differ significantly from the ideal. Use your vehicle’s average MPG (from the trip computer or past fill-ups) multiplied by 21 gallons to estimate the distance you can cover on a full tank.
Practical considerations
When planning longer trips, note that you may not be able to use all 21 gallons due to reserve and gauge calibration. Always refuel before you approach empty if you’re in unfamiliar territory, and carry a safety margin for unexpected detours.
Summary
The 2008 Acura MDX has a 21-gallon fuel tank (approximately 79.5 liters). This capacity informs trip planning and refueling needs, while actual range will vary with driving conditions and drivetrain.
