How big is a 2004 Acura TL gas tank?
The 2004 Acura TL is equipped with an 18.0-gallon (about 68-liter) fuel tank. This is the official total capacity; the amount you can use between fill-ups is slightly less due to reserve and gauge calibration.
What the spec means for drivers
Tank size directly influences how far you can travel between refuels, in combination with fuel economy. For the 2004 TL, real-world ranges typically fall in the neighborhood of a few hundred miles per tank—roughly 360 to 420 miles—depending on driving conditions, transmission, and trim.
Official capacity and practical use
Automakers publish the full tank capacity as the maximum volume the tank can hold when full. In daily use, usable fuel is slightly less than the stated capacity due to the reserve and gauge design. Understanding the full capacity helps with planning long trips and budgeting fuel stops.
Fuel economy context
EPA estimates for the 2004 TL place the combined fuel economy in the low- to mid-20s miles per gallon, with actual range varying by driving style and conditions. Steady highway driving yields the best range, while city commuter driving reduces it. Using the full 18 gallons at a roughly 22 mpg average provides an approximate range near 396 miles, give or take based on conditions.
Summary
The 2004 Acura TL’s gas tank holds 18.0 gallons (about 68 liters), offering a practical driving range of around 360–420 miles depending on driving habits and conditions. This capacity informs trip planning and refueling strategies for long drives.
